I just upgraded my router to a wireless one. Firstly, it's connected via ethernet to a PC and it is happily getting internet access.
On my i5500 I get a strong wifi signal. Wifi Analyser shows the signal at max constantly. I can also connect with Gmote and it works just fine.
The problem is that I can't actually access the net at all from the phone.
So basically I know that my phone is talking to the router with no problem. It's just getting out onto the internet.
Does anyone know of a solution?
try logging into your router and change the broadcast channel to something else and test it again. it should be something like a/b/g mode... define a single channel and see if it works.
I had originally thought that was working. It did for the first few minute where I had connection but then it just dropped.
I have noticed that I have some very small bursts where I can connect.
Do you think that trying the different channels may be the solution?
I have the same problem. Have you found a solution?
Still no solution. I went through every channel and every encryption method.
So far I've found that having the channel set on 'Auto' and then disabling encryption seems to give me internet connection through WIFI for at least the initial period but it eventually drops. But that's also not always.
I've also Googled it to death and found nothing. If you do find the solution please post it here and I'll do the same.
Maybe we can help each other.
make sure you entered the right password of wlan.
use a pc to connect the router and in the wlan you'll find the password.
Ok, just to clarify. My phone connects to the Router via WLAN. In fact I can use Gmote to control my PC. So the WLAN connection is great.
The problem is accessing the internet when using that connection.
I had similar problems with a router last year. I resolved the issues by flashing DD-WRT firmware. The manufacturer's firmware was junk.

I had that idea but they don't have firmware for my router yet. I have asked them if they intend to make one.
Any chance the firewall on your phone is blocking your browser from using the Wifi?
Sent from my DInc via XDA App
I have no firewall on my phone.
Ok I've tried some new stuff and they I've had the longest connectivity so far (which is about half an hour).
First I made sure my Wifi wasn't set to turn off when the screen goes to sleep. Second, according to a forum I read, Netgear recommends channel 7. If that channels doesn't work try 1,3,6,9,11,13.
I then disabled encryption.
Fortunately no one near me uses Wifi at all and I've got the kind of walls that stop the signal from getting outside.
Anyway. It's working so far but I'll monitor and report.
[edit] And I forgot. The router was checking for firmware but it wasn't actually finding so I downloaded it myself. Seems that also made a difference.
Ok. I can confirm after 2 and a half hours my internet connection is stable. I even left half way through and when I came back it connected perfectly.
So as a summary here's what I did:
1) Get latest firmware
2) Change channel to 7
3) Disable encryption
I will change encryption and see if it still works

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.
My wifi is very spotty at best. It always seems to say it connects just fine but it won't let me actually use it. I just went and stood right above my router and had full wifi strength and couldn't browse the internet. Are there any solutions to wifi issues or do I probably just have a bad wifi chip?
There could be a ton of different reasons why you can't connect. There might be a compatibility issue (some devices just don't get along), there might be an issue with security (you aren't using WPA2/AES on your router), there might be a channel issue that can be fixed by trying another channel on the router, the list goes on and on.
What kind of troubleshooting have you done so far? What router do you have?
Running a netgear WNR3500L with WPA2 encryption. All I've done so far is a simple restart of the router.
EDIT: downloaded and used wifi analyzer to see which channels were open and they looked to all be about the same. I switched it to 6 for tests without any improvement. My router auto detects the best channel to be on. Any other advice?
I have searched this forum and can't seem to find any good responses relating to my question. I am mostly wondering if anyone else is having problems with the data transfer speeds using a router with WPA personal key?
Here is my issue: I have WPA personal set up and I can connect fine to the router. But the wifi bars always stay white and data transfer is so incredibly slow that it pretty much isn't connected. It's really strange. Because I can use websharing app to download and upload files to my device on the computer, but the phone can't use anything else besides that. It never connects to google servers and the browsers don't work, or any app that requires data. So my problem is that data slows to a crawl for whatever reason. My phone has been like this since I have bought it. I have tried many many multiples factory wipes and different roms, nothing helps. The strange thing is that every great once in a while it actually works, just out of the blue.
I read a thread on here related to nexus s wifi issues and one guy found that the nexus doesnt seem to like wireless n with WPA personal. So I experimented and made my wifi open and the phone works fine! As soon as I add a passkey, it doesn't work. I have tried WPA personal 2, and that doesn't work either.
Does anyone else have this problem or know how to fix it?
The network at my house has a WPA encryption, my NS has always worked fine with it. Some networks seem to just be more troublesome than others. I'm sure there's a technical reason, I just don't know enough about the technology to speculate.
It's a very annoying problem. My brother's nexus one works fine, so this has me confused. I can't figure it out.

no N
I had the same issue... changing the routers 802.11 mode from B,G,N to just B,G worked for me...
I don't have issue with WPA, but I don't use N ...
Probably this is related to N only?
I use WPA2 and N. No issues. I'm on Apple branded access points (Airport Extremes).
In order to get N speeds you need to use WPA2 security. I was having the same problems with WPA and my NS losing connection most of the time even being next to the router. Once I changed the security to WPA-2 I now get N speeds and it always stayed connected.
i'm on WPA2 and it has no problem connecting to my WiFi N

check your password, check your bandwidth, check your settings, check your authentication method, check your DHCP, check your filter, check if blocking is enabled, check the signal strength, check for wave pollution, check for... everything

WPA2 + Wireless N = Good
WPA + Wireless b/g = Good
WPA + Wireless b/g/n = Bad
Make sure you do not have wireless N in any form (N alone, b/g/n or g/n) enabled with WPA security. Wireless N must use WPA2.
Thanks for the replies guys. I will try what you're saying.
Well I had WPA2 working last night. I had the phone turned off and charging when I went to sleep. Woke up this morning and same problem. What the hell is wrong with my phone?! Turning off wireless security on the router instantly solves the connection issue. Dammit.

No it does not. It seems it doesn't like password protected wifi at my house. I need to try a friends house or something. But my wireless settings are very basic and the phone works on it sometimes which makes no sense.

Okay, a little about my setup. I have tested on Slim ICS 2.7, 2.9; Codename Android 1.4, 1.5.5; as well as AOKP (I dont know exact builds, but am on the latest now - build 28). I have a Cradlepoint MBR 1000 which is a b/g/n 4g router (though I only have cable hooked up - was bought originally to allow me to broadcast my Clear 4g service, but Clear doesnt work where I live now).
EVO 3D, iPhone 4s, All my laptops, HeroC, Kyocera Echo, Roku...I mean everything connects to my Wi-Fi EXCEPT my NS4G...WTH?
Does anyone else have this issue?...could it be some settings with the N router?...I cant believe everything but this phone works.
Please help. It is so frustrating to be limited to 3g that works intermittently while I am at home. I have all my apps from the Google Play backed up to my sdcard so I dont have to connect to install them...it is a huge pain. Thanks in advance
Need some more description. What settings do you have on the router, how have you tried to connect, does it connect then drop out, can you see the network at all, etc?
Either your phones wifi hardware is gone or your house.
So here's what you can do to narrow down on the problem.
Tell me if you can connect to any other wifi hotspots outside your house. If it does connect then problem is router if it doesn't than problem is with the phone.
Good luck.

Not necessarily. Setup of each router can change in numerous ways so as to stop certain devices from working, as can certain phone settings not allow connecting to certain routers. It is not quite so black and white, and we already know the router works.

Sounds like a channel setting problem. Easiest way is to open up your router config and change the channel between 1 and 12 and this shouldn't happen again. Alternatively you could mess around with your build.prop.
Harbb is right, you might want to test several things within your router:
Change channels (use 1, 6 or 11-12)
Set it to only use on b/g connections (don't use n)
Different authentication methods (WPA2 with AES, etc)
And make sure you don't have a limit on your DHCP settings (just to make sure you don't have a ton of devices connected so it's not handing more IPs) or MAC filter.
Okay, sorry for not replying sooner. I posted this, then went to bed.
@Harbb:
It does see the network, lets me connect, put in the password, and says it is connected. It always says the connection is poor when I know it should be a good connection. The phone then shows the wifi icon and up and down arrows inside of the icon...I never see a portion of blue. When I try to download from the market, it will act like it is working, then the icon will disappear/reappear numerous times before it tell me there is not a connection.
As for my router setup. I do not know what information will help in this but here is some info: I do not have MAC filtering on, WISH is active (dont use it), WPA2 Only Personal AES (this is what I use), Channel 6 (I have tried channel 11 because I read somewhere the Wii needed 1 or 11 or one of my devices needed it), Transmission rate is Best, Channel is Auto 20/40 MHz, Mixed b/g/n (to utilize N and G, it has to be on this setting, there isn't an option for Mixed n/g), it is set on 192.168.0.x, NetBIOS mode type is Mixed (Broadcast then Point to Point).
@shockem I have not tested it with any other hotspot to see if it is just a problem with that router and this phone. I will try if I can find an open hotspot and let you know.
@Billchen0014 It does detect the network and connects, but drops it constantly...I cant even download a <1MB file from the market.
@Harbb (2) Going by your advice to daviki...it looks like I need to check another router. I go by a Starbucks, so I will try their hotspot...unless it isn't free, then Ill look around.
Thanks everyone who is helping me with this.
@Oogway, I will try G only and see what happens...if I use Mixed it has to be g/b or b/g/n. As for DHCP there is only 2 maybe 3 devices connected and No MAC filtering
Could it be the Wifi country code issue?
Is that something on the phone? Also, I tested different channels (1, 6, 11) as well as b/g and g only. Still no go.

Thanks for the info. Test another hotspot (preferably one with a wpa2 password too if possible) and let us know. I'll reply later with some things to try as I gotta get going.
Okay, I did test one more thing. I sat right next to the router and it had full bars. Stayed full and my speed tests were great. Moved to where I sit on the couch about 30 walking steps away and no connection. I know the signal reaches because it is where I use laptops and other devices. The PS3 and Wii are further away and have no issue. It is not a clear path, but there aren't any doors between the router and the couch.
Just some more info...leading me to believe it is an issue with the phone. I get horrible service with Sprint also, so it may be connected. I don't know.
Any ideas? Is it just because of how far away I am?
Again, thanks everyone for the help. It has been so frustrating ever since I got the phone.

Wifi Analyzer can give you a dB reading on the signal strength if you'd like to try that from a distance too. Wifi at uni likes to show low bars quite often, however alot of the time i have great signal and it shows through wifi analyzer. May not be related since uni is a peap connection, but worth a shot anywho. Might give another hint on whether you should seek out warranty or router settings.
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.
