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...

It appears to go beyond Samsung Galaxy, I've seen the same issue with Nexus and Motorola Droids. VERY frustrating!

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.

[Q] Wifi Connection Problems - Vegan-Tab

Need a little help. My G-tab is running current VEGAn-TAB rom. I am having problems getting the wifi to actually connect. My icon shows a good signal, and inside the wireless settings I am showing connected to my wireless network. I also went to advance settings and made sure wifi never sleeps. All apps that need internet connection (market, browser, etc.) show no data connection.
Used yesterday with no problems. My laptop is running on same network and working fine.
Any ideas?

have you restarted? Sometimes happens to me too but it's nothing a simple restart can't fix.

Yes. Restarted several times. Didn't work.
Oddly enough I have a Airave from Sprint to boost my cell phone signal, and it may have been the problem. When I unplugged it and returned to my G-Tab later the Wifi was working. Not sure why.

Could be competition on the 2.4 GHz frequencies. Some wireless phones and even microwave ovens can trash a wifi connection.

Moved to general

Anyone else having WiFi problems with Vegan? Since installing this mod, I can only connect to a WEP signal and not a WPA-secured network.

I can't connect either. Trying to connect to a wep wifi and it stays on "obtaining ip address from ..." but never completes the connection. Any help?

No problems with home WEP, office WPA2-PSK and several wide open public ones. I just wish the damn thing would auto-connect to the ones I have been to before.

My only guess is, if its a 5Ghz N Router you should check to see if it allows
2.4Ghz signals and not just 5Ghz. The GTAB doesn't seem to support connections at 5Ghz.

I just changed over from TNT Lite(latest version) and was able to connect fine but I didn't like the interface and some of the features. I've loaded Vegan tab 7.0.0 and I was able to connect at work (802.1 EAP) network but I can't connect to a wep wifi at home (were several other pc's are connected and working fine) and it stays on "obtaining ip address from ..." but never completes the connection. Any help?
I have a Linksys wrt300n router and have confirmed that it configured to accept 2.4Ghz & 5Ghz signal and have rebooted several times with no luck.

I don't have a lot to add to help you troubleshoot, but I can say that I am running VEGAn Gingerbread RC1 with pershoot's latest kernel. I am able to connect at home on a WAP2-PSK (Linksys Linux based G/N) at home, WAP2-PSK at the cabin (Linksys's cheapest G/N), and at work on a 802.1 EAP network (Cisco).
I has some unexplained issue mounting the internal storage on a computer. After a little head scratching, I started to wonder if it had something to do with the custom kernel I was running. I flashed Pershoot's latest kernel and my problems went away.
I mention all that to suggest that you might try flashing a different kernel and see if you get different results.

I have an issue with vegan where when i reboot the device (or turn off and turn on) wifi is off even if left on when turning off, i have to manually turn on wifi after every boot.

Have you checked to see if you're using MAC address filtering, and if so, that your gTab's MAC address has been added to the whitelist on the router? I get the feeling that that may be the issue. You have the WEP key on your device, but your router's still blocking it. I'm running the same ROM you are, and have had absolutely no troubles connecting to my work network with 802.1 PEAP, WPA/WPA2-TKIP and AES at home, and multiple makes/models of access points/routers.
Hmmm. Just reread your original. Now I'm wondering if you have enough DHCP leases available on your router. If you're out, you'll have to wait until a lease expires or add some more to your scope of addresses.
Hope some of that helped in some way...

WiFi authentication problems

I have been having issues with all my android devices and connecting to me WiFi. They accept the password but will continue to "obtain IP address" or "Authenticate". I have been able to get all my devices to connect by unplugging the router and plugging it back in, but I don't want to do that every time. I take my tablet to class with me, so it loses the home signal and then i have to unplug the router upon returning home. Thinking logically, it i either my internet speed or my router.
Any thoughts on a solution that doesn't involve unplugging my router every time my tablet leaves the house?
-Router problem?
-Network problem?
-android problem?
-security Problem?
I have
-Gnex(vzw)
-Nexus 7
-Belkin N150
-500 kilobit network
-WPA/WPA2-Personal (PSK)
-Known working password
Thanks for the help

It's a well known Android problem past 4.0 ICS, and does not happen with all WLAN routers but with some. Sad to hear it affects current Nexus 7 devices aswell.
Maybe you can try out your Nexus 7 on a friends router and see if the problem persists, if not, getting a new & cheap WLAN router might be the least worrysome solution.
Patch it directly into your old router (typical RJ-45 patch cable) and disable the new routers DHCP server. Voila, done.
The only other possible reason I can think of is if your current router is not broadcasting it's ssid. Hiding the name of your WLAN in it's broadcasts is something that gave me troubles past-ICS too. I resolved it by simply broadcasting my routers ssid, even though it lets my neighbors see my network (naming it random letters and numbers).

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.

Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris

It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.

You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.

I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.

I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4

No option for static IP in connectify

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.

Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.

I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.

Same issue here on OnePlus 3 even after factory reset.

I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

Wifi Connection Issues since Oreo

Is anyone else experiencing connection difficulties with wifi since Oreo? Both at work & home with good, strong wifi signals my phone struggles holding onto wifi. Continually drops & struggles to reconnect like I'm on the edge of a signal (but I'm not, mere feet from a router). THen once connected it'll sit with an x through the icon.
Never had this before the update. On bone stock, locked Oreo OPR6.170623.011. Already tried resetting network settings to no avail.
Edit: Been running in safe mode for awhile and it seems to have alleviated the issue. So now it's time to figure out what app isn't playing nice.

I had that. Turned off such to mobile data automatically

I had the exact same issue. I factory reset my phone twice and did not restore any apps and had the same problem. Phone was under warranty so received a replacement which I am keeping on 7.1.2 for now. No issues yet.

I have a Unifi AP lite setup. Maybe I never noticed it before, but I was using a Rasberry Pi as my manager, but now I'm using an actual cloud key.
I've tried messing with all manner of settings and channels and band steering and AP names with no luck. My Pixel XL 8.0.0 will connect stay on for a bit and drop then reconnect. It never misses a beat, to be honest, I don't notice drops in connection. I am also noticing it in my Nexus 7 2013. My laptop seems stable, my girlfriend hasn't said anything about her iPhone or laptop. My Xbox one is stable, as is my switch.
I've reset network settings and tried the safe mode thing with no luck. I may do a factory reset this weekend if I can find the time.
In the mean time, I'm happy to have unlimited data at the moment.

I think I've narrowed it down to using a custom DNS. I was using a RasPi with Pi-Hole and my phone could not stay connected to wifi. I turned off the router pointing to my pi and boom, strong signal.
I tried manually assigning my IP / DNS etc in android 8.0.0 and it would not connect or hold a connection. I tried to connect it to 8.8.8.8 with no luck either. Back to stock DHCP assigned and I have a strong stable connection.

same issue not too sure what to do...is there a way to downgrade wifi driver?

So I have a stupid network, I'll try to upload a diagram of it here. My apartment internet only comes in in the kitchen and cannot go anywhere else unless I get a different provider, even then I'm not sure.
I moved the Pi to the router/switch that connects to the AP instead of on the other side of my network bridge and I have had 0 problems since. The attached diagram is my old setup as I was trying to explain it to people. Sorry it's not very pro.
