Polaris: WLAN problems?

Hi all,
I recently bought my HTC Polaris. It's the first wireless device I have, so I also bought a WiFi router to test it. I do not have any previous experience with WiFi on WinMobile, so the problems I am having could just be due to my newbie-ness...
I initially set my WLan router to WPA-PSK. I was able to get my Polaris connected, but at random times and repeatedly the device would stop receiving data (using IE, Google Maps...) with no apparent reasons. The wlan was still shown as connected in . At other times, it was unbearably slow. Sometimes it was difficult to reconnect after that.
Now I set my router to unprotected WLan, just for the sake of test. The connection with my Polaris seems more stable. I will keep testing.
In both situations there is something that puzzles me. In Settings-Connections-Wireless Lan, Main tab, it shows:
Tx speed = 54 Mbps
Rx speed = 1 Mbps
Also in the Advanced tab, the status is always shown as "Associated to the network" ("Associato alla rete"). I never saw "Connected to the network" ("Connesso alla rete") here.
Is this right? Did anyone else experience problems with the Polaris WLan? Is it possible that it works ok with no encryption, and doesn't with WPA? Please help!
*update*: while I was typing I was looking closely at the Rx speed. It seems to jump anywhere from 1 to 54 Mbps (but mostly stays at 1). I did not move the Polaris during this test. The signal strenght is good. The WLan adapter of my PC (where I'm typing looking at my Polaris screen) shows it as "excellent" and the connection pc-router is absolutely fast and stable.
I have no clue of what it can be.

WLAN Problems
This may not be related but I am managing to use a Netgear Router with WEP, however I do experience a lot of drop outs but more importantly I can't get any connections with the phone unless the battery saver setting is set for max performance. The phone also gets quite warm after 15 minutes operation on this setting.

as enterpryse has suggested you could go to settings>connections> wireless Lan> Power mode and move the cursor to best performance.
let me know if anything changes.

I'd say this is the best bet too.
But if you still having trouble try to reconfig your router allowing basically anyone regardless of topology to connect with it. And try using your pc simultaneously to see if it’s the router.
It could also be certain pages that you browse or maybe you router is updating too frequently I had that problem the other day because but kept updating my router for me.
And how long does you device take before it get quite hot? would i be out of line if i said maybe its because you're insulating the device with your hand? (I know the device needs to be held lol but that might be the only answer to your problem unless it’s an excessive heat problem then I would consider contacting HTC / the battery manufacturer / processor manufacturer)

Well, I'll be...
I kept trying to duplicate the problem. I set my WiFi router back to WPA as it was before when I was getting problems. Same PSK.
But after the first bad experiences (and my previous post), no more problems. The Rx speed is usually 42 to 48 Mbps now. It looks like this was the indicator that something was wrong in my first attempts, when I always got Rx=1. At 42 or more, everyting goes fast: Opera, Fast GPS, Google Maps... And I did not experience any more connection drops, data flow hangs, or slowness in connecting to the WLan.
The WLan router was already working fine, since I was already connected to it with my pc. I cannot explain why it didn't almost work and it's working fine now. The only thing I changed was the WLan channel. Could this be an explanation?

Of course, are there any other wlans around you? If they are on the same channel your router goes down with the speed till a stable connection is established.
Even if you have other wireless device e.x mouse, headset, keyboard. They often transmit on the 2,4GHz band an interfere with wlans.

Can't even load wireless mode!
I've just received my Touch Cruise and have started setting things up. I'm a previous owner of the Hermes so I know my way around the device. Or so I thought...
Using Comm Manager to start up wireless lan, when I click on the button, it thinks for a while but doesn't load up WLAN. The button stays in the "off" setting. Tried pressing a few times, no luck.
Tried switching off all other connection types and just switching on WLAN - still doesn't work. Tried using the hotlink via "Wireless LAN" icon through settings/connections to turn WLAN on. Still no luck. Resetting makes no difference.
Phone is otherwise working brilliantly. Looks like a driver issue, as I had a similar problem from time to time on the Hermes with Black ROM. Any ideas on what else I could try?

le_paulo
"Resetting makes no difference."
Did u do a soft or hard reset?

@Jackster - both soft and hard reset tried. No difference. But after the hard reset I re-installed Goodlink which threw up an error message "Communication port WIFI is locked down". Which suggests to me that WLAN is visible but access has been restricted somehow.
The question is why (??) and how to undo it...
Nothing a cooked firmware can't fix
Meantime, if anyone knows registry settings I should check to do some basic diagnostics, I'd appreciate it.

I got the same problem. I changed the connection settings of ActiveSync to
allow wireless connections when connected to a desktop computer.
Maybe this will fix your problem.

Same problem here. Tx = 54mbit Rx = 1 mbit. Sometimes it works ok (with Rx 24-54mbit) but most of time there are huge drops so i cant use wlan at all.
My Nokia N95 works excellent at the same settings with same router.
My polaris wlan battery is set to "Max Performance".
Any clue?

weird
This is the second XDA Orbit 2 (Polaris) I've had in a week. I returned the first one because of WLAN problems. Exactly the same with this one.
I have a Netgear DG834GT, WPA-PSK encryption set to 'auto 108mbps' on channel 6. As other posters here, tried no encryption, changing channels, g only, g & b, as well as all the other suggestions on here. All I got was Rx=1, screen icon showing connected and no web access etc.
Then I noticed that my Orbit 2 mac address appeared on the Wireless Station Access list in my router wireless settings. I clicked on the Add button to add my XDA to the Trusted Wireless Station list (but Access Control was NOT switched on) and EUREKA, it started working, but not very reliably. Surely this shouldn't be necessary. I have had an XDA Orbit for a year with absolutely no problems, so I know my around the new one. There must be a problem with the Orbit 2 - surely we can't all be wrong?

Resolved: HTC Fuze lost wifi

My fuze's wifi worked fine with a Zyxel router and a Belkin router configured as a dd-wrt repeater, for 6 months. Last week, verizon came to install FIOS and upgraded their old non-wireless router with a new one. Since then my Fuze can't see internet through wifi anymore. And it doesn't see the router's home page at 192.168.1.1 either.
However it is able to join the wireless network (WEP, SPA2, etc password portected) and get an ip address through DHCP or static. If it is static IP, then the router can see it as a static IP. My other wireless devices can all connect to the new router, including an iphone and the dd-wrt router configured as a client.
Initially I thought it was some silly settings between the new router and the phone. But after I exhausted things to try, I put the old Zyxel back on, and it still doesn't work. I also checked Fuze with our public library's open wifi, no luck either.
I just did a hard reset, reloaded the at&t rom, still same problem.
I did search the forum, and found a related thread, with no solutions in it--http://forum.xda-developers.com/showthread.php?t=441889
Any help is greatly appreciated!
ETA: A number of people mentioned the power setting of wifi needs to be set to max performance. While I have always had my set at max battery, and wifi worked find perfectly until the change described above, now I set it to max performance it is working. And set it to middle or any other place it doesn't work. I think it is some response time setting on the router.

Not sure if you've tried this, but figure I'd mention it anyway in case you forgot. I'm not too sure what this does myself, but isn't there a setting to tell the Fuze to connect through the "Internet" instead of "Media Net" or something like that? Maybe you forgot to change that setting, but it doesn't really make sense why getting a new router would be the cause of loss of wifi, unless the wifi chip went bad at the same time you got the router, which I don't think is likely?

Under wi-fi settings there is a choice between connecting to "The Internet" or "Work". But my phone has always been set to internet.
MediaNet is about the cellular signal's data service. I am using it it for the GPRS and 3G setting.

resolve: power setting did it
A number of people mentioned the power setting of wifi needs to be set to max performance. While I have always had my wifi set at max battery which is the default setting, and wifi worked find perfectly until the change described above, now I set it to max performance it is working. And set it to middle or any other place it doesn't work.
I think it is some response time setting on the router that is affecting it. My old router must be more forgiving.

Thanks
Changing the wifi battery setting from Best to performance worked. Thanks, I was getting frustrated.

Hi any one knows why does the Fuze has to be set to best performance for wifi to work. do we have any solution to come over this issue.

Home WiFi connection problems

Hey world,
I'm having trouble with my Roger's branded Samsung Captivate SGH i-896's wifi. The phone is completely stock. When I connect to my wireless AP at home it doesn't seem to always work on the captivate... I had a htc magic before running all sorts of different roms and never had a problem like this before.
What happens is that I would connect to wifi at home and it would work, but if I leave wifi on the phone for an extended period of time and go back to the phone, wifi stops working.
It would show that i've successfully connected to my AP but no data would pass through my phone.
Disconnecting and reconnecting to the AP doesn't seem to work, the only way to fix it is to restart the phone. I'm not experiencing this problem with any of my laptops, netbooks or cellphones at home.
Security type is WPA2.
Is anyone else experiencing this problem? Anyone have an idea what could be causing this problem?

I have had this problem intermittently, So has my wife on her Captivate. No idea what causes it though. It's a pain because if WiFi is on, but not working, 3G doesn't kick in so apps just don't work.

my wife's captivate has this issue as well (but I don't on my captivate). It will work for a short period and then stop. We have a fios wifi router, not sure if that matters at all.
restarting the router and/or phone usually fixes the problem

mine is a linksys... hrnnn

I'm having the same problem on my new Captivate. Tried it on several different networks with the same results (shows connected but no data will transmit) before I took it back to ATT. They scratched their collective heads and rebooted (powered down and removed battery), which is a temporary fix, but its been working for two days now and I turn off WiFi unless I know I'm in range of a working hot spot.

I was having this same problem until I set my wifi policy to never sleep, dont know if it is a fix for everyone but it definitely fixed my problem.

Glad to hear I'm not alone!
I've been fighting with this issue for over a week now, it suddenly started occurring. I wonder if it was an app we all loaded that suddenly made this condition occur? If you look the phone is requesting an IP and if the IP given back by the router is the same one it already has the phone doesn't acknowledge that command. If the router is rebooted then a new IP is given, or what is considers new. This is a HUGE problem and I've put in some time looking at it, but one of the problems is that is comes and goes. What your router log and you'll the phone request an IP over and over again, all the while the router saying "here, take the same one you already have back".
If you use the app "Network Info II" you'll see the problem when it displays a "Device IP" at the top of 192.168.1.254 and WiFi IP address will be the correct one, in my case 192.168.1.108. When we have these two IP numbers showing differently the device is hosed. Rebooting will put them back in sync, but that is not the proper solution, we need to get to the bottom of this! I understand the WiFi IP address showing at the bottom but the "Device IP" I do not, why the difference? How can we affect the "Device IP", where does the device get that IP address?

Try the app called WiFi Fixer. That did the trick for me. There seems to be a bug of some sort that causes the phone to not release the IP address. Or you could use static IP but that worked only for a while.
Cheers.

The phone gets the device IP from either the service provider (when using edge/3g), or from the router (when using wifi). If an IP address is not provided, it uses a default IP address, which is always outside of the standard private IP block.
There are two ways to assign an IP address: dynamically and via static IP address. Dynamic = assigned by the router, static = pre-programmed by you. I don't know if you can set a static IP address on a phone, as I've never tried it.

I had a zyxel wireless n router in my house and could never get the wifi to work on my captivate. If it did work it lasted 5 seconds... I was really pissed.
I was thrilled to see that buffalo is now back in the market and with dd-wrt firmwares... So I picked up the most expensive one they had for $89.99.
it has a dlna client built in as well as bit torrent, also lets you use a spare usb hard drive as a nas... things i don't know....
However loaded up the wireless settings in 2 minutes and voila... perfectly working on my captivate... I have also found that this router works flawlessly with G+N devices and it is gigabit. I was able to stream 1080p video from my synology 411+ to my ps3, download on the captivate and be on two other laptops at the same time without any issues... I am very very impressed with the buffalo.
Here is the product info.
buffalo nfiniti wireless n high power router and access point. WZR-HP-G300NH
ohh and my laptops are connected fully at 300 mbps with this router wirelessly...
very very happy with it.... Oh and forgot to mention... once this started working with the buffalo i noticed my batter was much better running on wifi all the time. Also wifi file explorer pro works flawlessly.. I was able to upload a 700 meg movie to my captivate wirelessly in about 2 minutes.

WiFi fixer did not fix my problem as well. After turning WiFi on the device IP remains 192.168.1.254 while the WiFi IP is correctly set at 192.168.1.108. When these two IPs are different WiFi does not work and WiFi Fixer doesn't appear to see any problems here.
The router here is an Asus RT-N16 running Tomato and I'm fairly confident that isn't the problem. This is more like an internal routing issue inside the phone.

I don't think it's brand of router that matters... maybe a setting on our routers can fix this...?

I've searched the internet to find a sol'n but it looks like this wifi problem is a widespread problem for almost all galaxy S devices... ppl have made temporary workarounds (ie. setting a static ip) but ultimately, there is no fix for this problem.... gg...

I dont know why nobody even notice that answer !!!!
had same problem on my milestone .. it is not a bug , wifi goes to sleep , its the way your phone is set up ... as its quoted here set it to never sleep and make sure your not using soem kind of app that will overwrite that setting ( like battery manager that for example could turn off wifi to save battery)
very easy to double check once your wifi is not working , go in wifi settings scan and check the wifi access points you normally use you ll see its set to disabled ..
the bug is it doesnt resume like it should. or gets re-enabled however you wanna call it . just re-enable it voila ! no reboot needed .

I got it working!!
This may be my first post here, so be kind...
Running Cognition v2.3b3 and Linksys WRT54G router. WIFI was working fine until I flashed to Cog 2.2 Then I could only use WIFI tethering, no other WIFI connection would work.
I tried setting up static IP and setting sleep to never. Didn't work. Changed router security from WEP to WPA Personal and got it working.
Phone settings: Go to Wi-Fi Settings, click menu, and goto advanced. I don't know if all the settings here are necessary, but I'll post what I have.
Port = 80
Use statis IP = checked
IP address = 192.168.1.103 (check your router assignments for an open address)
Gateway = 192.168.1.1
Netmask = 255.255.255.0
DNS 1 = (check your router config. For my router it's located under the Status, then router tabs.)
Router settings: (Under the Wireless, Wireless Security tab)
Security Mode = WPA Personal
WPA Algorithms = TKIP
WPA Shared Key = (your access key used when you attempt to athenticate from your phone)
Group Key Renewal = 3600 seconds
Write the access key down so you can use it to reconfigure the other wireless devices on your home network.
Good luck,
Glen

changing my router fixed the issue.
I have wifi running on my captivate for 8 hours at a time at work now and at home. Not one hiccup or disconnect, works 100%.
99% of wireless routers are crap. I work in IT and have dealt with most major brands and had been running linksys wireless routers with dd-wrt on them...
if you got a spare 90 bucks.. go to your microcenter or place where they sell buffalo routers and pick one up. If it doesn't work.. you can return it.

This worked for me

Going to a static IP worked for a few hours and then it stopped working as before. WiFi is set to not sleep.
When I ran the router without security I did not have this problem and since adding WPA2 w/AES+TKIP the problem has developed. The iPod Touch doesn't have a problem with it, nor my laptop or wireless ipTV set-top box, only the Android. I'm leaning towards setting up another router without security, on a different channel, and see if the problem disappears again. Here in 2010 we shouldn't be having this issue, but look on other forums and you'll find similar complaints with other brands of Android phones, it's not a Samsung thing.

WiFi Connection Issues

Hello all!
Not sure if this has been posted but I figured I would put up a new post. I am showing that I am connected to my home WiFi but I am not able to actually use it. For instance, I cannot open links or watch YouTube videos. I believe it is the router because I just had a Droid RAZR and my connections to the Internet were not dependable. Currently, I am using AT&T's 2Wire 2701HG-B Gateway router.
Are there any settings that should be adjusted within the router? Encryption type is WPA-PSK. Wireless mode is 802.11g/b.
I just got my S3 yesterday and so far WiFi works in other places. Also, I tried the #*0011# thing and that did not work for me. I've rebooted and factory reset my device. Nothing helps. Anything I can change?
Thanks in advance!

Does your router Administration panel (perhaps accessed via a web browser?) show your phone as connected with an assigned IP address?

Now that I'm looking, no it doesn't have it listed there. My phone says its connoted though. I forgot the connection, rebooted the phone and did the #*0011# and reconnected the network. Still the same result. Any ideas?

I've seen some routers being a bit buggy about showing all wireless-connected devices (my dual-band Netgear comes to mind), so I can only think of a few things to check:
This assumes your router is configured for DHCP and that you have addresses available in its configured range, etc.
1. Does anything else use this router successfully to access the Internet?
2. On your phone, Settings -> Wi-Fi->(click on the wireless network you are "Connected" to)->View, does it show an expected speed and a valid IP address from your router?
3. If (2.) revealed a valid IP address on the phone, can you ping that address from another system attached to the same router?
4. Did you connect the phone using a typed-in passphrase on both router and phone or by using the Wi-Fi Protected Setup (WPS) push-button method on the router? I found that, no matter how carefully I typed the passphrase, it often would not connect to my desired network because something was somehow amiss. However, this phone is compatible with using WPS, so I used the router's push-button method and it connected easily + worked fine.
Just some things to check and ensure nothing critical is amiss.

1. Yes, my iPad and two laptops.
2. There is a link speed and an IP address but the third number of the IP address on my phone is different than the third number of the IP addresses of the devices listed that connect to the router. I hope I made some type of sense saying that lol! There are about 6 devices listed that connect to the router and the first, second and third numbers are the same. My phone only have the first & second numbers in common.
3. didn't try that because I'm assuming something isn't right from the previous answer.
4. I typed in the pass phrase from my phone. I do not know of any other way to connect the device. I am not familiar with doing it from the admin panel especially since I'm not even seeing the device there.
Thanks again!

Yeah, not getting the proper address range would be indicative of a problem authenticating with the router, I'd suspect. If you are using the default router configuration, it should have an IP address of 192.168.1.x, where x = {some number}
You might try temporarily setting the router to "WEP-Open" and no passphrase on the phone (i.e., connect to the open network) to determine if the phone can obtain a valid IP address from this router before doing more debugging. This might weed out the possibility that this new phone has an inherent problem connecting with your specific router - even though other devices don't have such issues, maybe the Galaxy S III is sensitive in this regard.
Consider ensuring that the "Power setting" in your wireless configuration is at its maximum value (10?).
Aside, I don't know if the latest firmware enables WPA2-PSK, but that utilizes AES and is often more efficient than WPA-PSK, from my understanding. If using WEP-Open works for your new phone in the above test, then consider setting the router to "WPA-PSK and WPA2-PSK" (if it has that value) and try reconnecting using the passphrase (either 10 or 26 letters/numbers) - that setting should be compatible with your other devices and not require them to be reconfigured, I believe.
This topic seems to indicate people have problems with your model of router in making and keeping wireless connections at times, sometimes needing to hardcode the router down to only use "b" protocol (i.e., slower) for maintaining stable connections. I don't think that's the case here, though.
This User Guide (.pdf) for your router model does not seem to show that it offers WPS as an alternative for establishing device connectivity. From my recollection, my phone would only connect reliably to the router using encryption when I used the WPS button on the router. That's why I asked you to set your router to be Open for a test.

I had the same issue as you. I would be connected to my router and nothing at all. I am using a att modem/router along with my netgear wndr3800. But wifi was dropping a lot of the time. I never had this problem before when I had my Rezound. 3 days before I got my S3 I upgraded the firmware on my netgear router. I am guessing my S3 didn't like the firmware update or something. I tried everything in the router settings to doing a factory reset on both the att modem and my netgear router. Nothing... So I honestly thought it was my phone. Called Verizon and asked them to ship me a refurbished. So, I thought I would try one more thing. Revert back to my old firmware on the netgear router. Well it worked. Since Friday night I haven't had the issue you are having. Connected to my home wifi with no drops at all. It could be the firmware. Wonder if you could revert back. On a att modem/router I am not sure.

If using WEP-Open works for your new phone in the above test, then consider setting the router to "WPA-PSK and WPA2-PSK" (if it has that value) and try reconnecting using the passphrase (either 10 or 26 letters/numbers) - that setting should be compatible with your other devices and not require them to be reconfigured, I believe.
This topic seems to indicate people have problems with your model of router in making and keeping wireless connections at times, sometimes needing to hardcode the router down to only use "b" protocol (i.e., slower) for maintaining stable connections. I don't think that's the case here, though.
This User Guide (.pdf) for your router model does not seem to show that it offers WPS as an alternative for establishing device connectivity. From my recollection, my phone would only connect reliably to the router using encryption when I used the WPS button on the router. That's why I asked you to set your router to be Open for a test.

I tried WEEP-Open and that did not allow me to connect either. I did set up WPA2 but I still was not able to connect. The power setting was set to 10. Not sure how to manually add the device which I was going to try. I've forgot it several times and added it again but it does not work. I did connect at a different location. Not sure what else to try. Even tried changing the channel.

If it's not connecting to your router with WEP-Open, then something different is going on. I looked in the manual for MAC Address access lists, but that doesn't appear to be a feature of this router (unless it was added in a firmware update which came after the manual was published - if this was the case, your laptops and iDevice would have had their MAC addresses added to the router as another layer of access control to the WiFi network).
Sorry, I'm out of ideas on this one. You seemed to say that the Samsung connects to other WiFi points, so perhaps there is an inherent incompatibility between this router model and your phone which can be reported to Samsung and/or Verizon Tech Support - for all we know, this is a known issue.

I had the same issue as you. I would be connected to my router and nothing at all. I am using a att modem/router along with my netgear wndr3800. But wifi was dropping a lot of the time. I never had this problem before when I had my Rezound. 3 days before I got my S3 I upgraded the firmware on my netgear router. I am guessing my S3 didn't like the firmware update or something. I tried everything in the router settings to doing a factory reset on both the att modem and my netgear router. Nothing... So I honestly thought it was my phone. Called Verizon and asked them to ship me a refurbished. So, I thought I would try one more thing. Revert back to my old firmware on the netgear router. Well it worked. Since Friday night I haven't had the issue you are having. Connected to my home wifi with no drops at all. It could be the firmware. Wonder if you could revert back. On a att modem/router I am not sure.

I've tried every way possible to find a way to revert back but it does not work. No success. I've noticed that this S3, my old razr, & another android phone does not actually connect. The comet (3rd phone) actually appears on the the panel but the ip address on the phone is different than what is showing on the admin page for my router. The phone does show whereas the razr and s3 never even appear in the list though they say they are connected.
I'm at a dead end

To be honest. It's not your phone. I think you said you already did a factory reset on the modem/router correct? If not, do it and revert back to factory settings. If that doesn't work I would call att and tell them to send you another att modem/router. Tell them your wifi is down. Hopefully you'll get everything back to where it was. Good luck.

This is what finally worked after two weeks of researching! Found this here for the toshiba thrive but it worked for mr! http://www.thriveforums.org/forum/t...1-thrive-will-not-connect-t-2wire-router.html
I tried this part but all of my settings were already set to match this....including it because it was part of the process.

When we put in the password for the connection it saying it is 'scanning' and 'connecting' then disconnects and starts going into a scanning loop saying is scanning then stopping then starting again.
I found a similar topic about this but the thread did not answer my question. I followed all of the steps of given solutions to no avail. And the constant suggestion to set the beacon or preamble differently is highly frustrating because the model router I have does not have such settings (I have gone through all the menus about ten times, literally).
I have also heard that the connection security could be a factor but I am not willing to downgrade my WPA 2 (TKIP & AES) to a WPA 1 or WEP, unless its absolutely necessary. I've been googling for hours so I need a solution or unfortunately we will have to return it for a more compatible device, which would suck because we got this for a good price (new).
Our router is a 2WIRE 3800 hgv-b (we have AT&T Uverse, idk if I should specify anything else)
Any help would be greatly appreciated.
Hi shakefry - Nice to meet you. You are 100 percent right you should not lower your security - WPA2 is the strongest and it does work fine with Thrive. That is what I use.
For some reason the ATT 2-wire routers are the most frustrating, but that is not a problem. We just might have to try a few different things, instead of getting it to connect the first time, so stay with me, OK? big brothers always have to help their little sisters...
----
1. You do not have MAC Filtering enabled,do you? If you do add the Thrive's MAC to the Router's list of permitted devices. Then try connecting.....
2. Not using MAC Filtering, or you added the thrive and still can not connect ......
OK, First ... Lets get the info your Windows Laptop has about your router when it connects
successfully to the 3800HG-B Router via wifi:
On your (Win7?) PC that is successfully connected by wifi to the same network, lets get some wifi settings. Vista - pretty much the same screens, XP a little different looking.
Click on the wifi signal lower right taskbar, open network and sharing center.
click on right side in blue, your network name
Pop up window - click on Details
the detail window opens ...
IPv4 Subnet Mask should be 255.255.255.0, if not we need to change it in the router settings.
This would prevent you from getting to the internet, but with all devices not just thrive.
Copy down IPv4 Default Gateway, and both IPv4 Servers
(Most routers will not need the actual IPv4 addresses in the devices DNS1 and DNS2, but yours might)
Now (no picture) close the DETAILS window and click on WIRELESS PROPERTIES. click on SECURITY tab, then click on SHOW PASSWORD. DO NOT CHANGE THIS FIELD, YOUR PC WILL DISCONNECT. WHAT YOU SEE IN THIS FIELD IS THE CORRECT PASSWORD TO YOUR NETWORK.
(I just want to be 100 percent sure - this is the password you need to log the thrive on. You are pretty sharp with all this stuff, so you know it is case sensitive, don't mistake a "zero" for the cap letter O, etc.
We will try using these when we set Thrive's wifi settings for your network.
(Go to link to find the screenshot)
Now please check the following router summary page by logging on to your router.
Make sure, on the right side it, shows enough DHCP Available, and on that the router
address is still 192.168.1.254
And on the left, the page is exactly the same as below, none of the blank fields are filled in, right?
And the top button is still selected ..... 192.168.1.0/255.255.255.0 (default)
--------------------------------------------------------------------------------------------------------------------------------------------------------------
THIS IS WHERE THE ACTUAL FIX CAME IN
Originally Posted by shakefry

No filtering wont "pull in" the devices, through the front door of the router. Filtering will just turn them around and kick them out again if they are not on the "invited to the party" List.
"edit: I just found a similar page, the design is slightly different. The router/gateway address is one number above my DHCP range and it says I have 178 available and there are 12 allocated (weird because we only have 10 devices connected to this thing that I know of)
OK so you have plenty of available IP addresses (DHCP). It is normal to see a couple more than the number of devices you have."
So now you have the info you need to connect the thrive (maybe):
1-Hold the Thrive in portrait mode so the keyboard does not hide the settings
...
2- Go to Settings >> Wireless and Networks >> Wi-Fi settings >> tap your network name, Tap FORGET
Now when your network name shows up again under wifi settings ....
select WPA2
Enter password, it is case sensitive.
3- tap the triangle where it says DHCP, select "static"
enter 192.168.1.173. (a nice odd numbered unused ip, away from the auto assigned ones).
(You are making it an odd number (173) because if you buy, in the future, something like a network drive, or AppleTV, it will probably come with a nice "multiple of five" static number like 150 or 155 or 35
the "CONNECT" is greyed out .... right?
4- enter routers gateway 192.168.1.254
enter prefix 24
enter dns1 192.168.1.254
5- the"CONNECT" brightened up again? Tap CONNECT.
....... OR ..........
CONNECT is still greyed out? Enter DNS2 192.168.1.254, tap CONNECT
ARE YOU CONNECTED???
If NO
1- update the router's firmware - try connecting again
2- We will give up on the 3800 and add your second router, with different sets of DHCP ranges, and broadcasting on a non-conflicting channels to the 3800's channel ( channels 1, 6, and 11 do not conflict with each other - assign one router to channel one and the other to channel 11, and keep them a couple of feet away from each other.
shakefry, Please Let us know how it goes, which solution worked ... so other forum readers can help their little sisters too ....
we are standing by (actually in my comfy recliner waiting ..)
Thanks, bobj

Glad to hear you got it going. I actually fixed mine about 3 days ago. I read somewhere changing your ssid inside the router helps. Well, I did and it actually worked. I haven't had a problem with my wifi signal yet. On mine what was happening also was whenever my phone would go into sleep for say 5min and I went to use the Internet immediately. It would take the wifi about 20-30secs for the wifi to wake up. So far, since changing my ssid I haven't had that problem at all.

Thanks for posting a followup.
Did you delete and re-add the WiFi network on your phone, configuring it for a static route and IP address that was in the range on the router, essentially?

Sony Xperia XZ Premium WiFi issue

Is anyone here also experiencing the same problem with me?
I found that from time to time, my XZ Premium losses WiFi connection and can't find any hotspot until I turn on then turn off airplane mode, or just restart.
Here are the screenshots form my S7 edge (SM-G935F) and XZ Premium, they were next to each other and very close to the router.
Please help me, thank you.

Screenshot from XZ Premium.

are you using 5G? if you are, you need to update the wifi channel and band through your router settings. that's what i did with mine and now i don't have that intermittent wifi connection anymore.

Sure, thanks, I will give a try, and can you please tell me which channel and band should I use?

Anyone found a solution for this?
Wifi was spotty before the Android 8 update but now it's almost unusable. Every now and again it will just stop showing wifi connections, toggling wifi on and off might show a connection or 2 but it will either disappear or just say "Disabled" when trying to connect to it. Reboot solves it for a little while.
Usually use 2.4Ghz wifi with a variety of router brands.

Happens here on Android 8 as well, quite annoying to be honest. Sometimes drops the connection for no reason, and then when I click on WiFi settings, it doesn't show any connections till I turn WiFi on and off and even then it'll only show 1 SSID, turning it off for a while longer and then turning it back on brings back the rest of them and then it'll connect, but it's stupid how I have to keep doing this every few hours.

I set my 2.4 and 5 GHz bands to different names and join only the 5 GHz, and I don't get drops. On Oreo rooted.

i have xperia xz premium with Oreo 8.0 I encounter the same problems when I'm connected to my wifi, suddenly the data connection is blocked, and when this happens I have to turn off and on the wifi symbol to restore the connection. I do not understand why this happens. My phone is updated to the 47.1.A.5.51 system with November google patches. My modem is Billion Bipac 7800N

So it seems to be a common issue, anyone know if Sony is aware of it?
Where can we complain? It's their damn top of the range phone and it's most basic function isn't working right.

Knock yourself out. I've had more than one device with the Snapdragon 835 behave in this way, so I think it's a chipset issue.

Do a Google search for WiFi and Oreo and you will see that this is affecting multiple cell phones.
Do they all have the 835 chip in them???
I think it is an Oreo issue.
I have no such problems and I have Oreo and the 835.

Try disabling IPv6 on your router.
This is still OS/firmware issue but this temporally fix the issue

I found the solution:
My network works with two devices:
1 ZTE Router (2.4GHz)
1 D-LINK Repeater (2.4GHz)
In the router my XZ Premium works nicely, in the repeater happen exactly what you said, Connect apperars "no internet" after 1 second and wifi on Smartphone is automatically disabled or wifi stay enabled, but says "disabled" on network.
So.. I checked the wlan settings of the two devices in my network exhaustively item by item and I changed the devices settings about 20 times, I and I found that none of the settings matters (wpa or wep, 5Ghz or 2.4Ghz, Bandwidth 20Mhz or 40Mhz, type of network b / g / n, nor channel 1 to 13) just ignore this.
What REALLY MATTERS is a option in the advanced wlan settings, called "Fragment Threshold" this value was at 500, I changed it to the maximum (2346) and my XZ Premium started the connection instantly. Explaining: increasing this value defined that the packet can be up to 2346 bytes before being fragmented, so we deactivate packet fragmentation, reducing overhead and ensuring the best transmission rate possible, so this option determines the size of the frame.
Put simply: Go to advanced Wlan settings, locate "Fragment Threshold" and change to the highest possible value. That worked for me =)

worked for me
1- turn off wifi in being wifi settings ie where you view your wifi networks
2- select "scanning settings". it will show once you have turned your wifi off
3- turn off wifi and bluetooth scanning
4- go back turn wifi back on and enjoy
