Anyone else experiencing problems with the Wlan? Everyday I have to shut down Wifi, and start Wifi again to reconnect to my router. This mostly happens after the phone has been unused for a few minutes.
When I start using the phone again, it still says i´m connected, I still have the IP, and the signalbar. But when trying to use the internet there is no connection.
My X10, asus lamborghini, hp laptop and desktop pc works flawlessly, so there cant be anything wrong with the router.
Would like to confirm that this is a general problem, and not just my phone...
I didn't have this problem until I played with the WiFi sleep policy. I switched it from 'Never' to 'Sleep when screen is off' and I then got the problem you described. I have since switched my phone back to 'Never' and the problem has gone away.

Yeah, I have mine set to never also. Still have the same problem.
Just added a videon on youtube to show how it keeps disconnecting itself, and how I restore connection.

I've got the same problem with my phone, its really annoying
There are three threads and one poll dedicated to Wi-Fi. There was no definitive answer in those threads so I doubt there will be one in this thread. Do a search.
Same problem here, not sure if it's down to running a customer rom, anyone having this problem on stock rom?
Yes I've had this problem and tried to send my phone back over it.
It appears to be a problem with WPA1 - the wifi driver hangs and the phone kills it (from adb logcat).
It happened on my home wifi - I switched it to WPA2 and it went away; however, my employer uses 802.1X and I have to use HSPDA at work as wifi keeps crashing.
Please god, not another ten pages of the same questions, theories, and debates. Here's the original Wi-Fi thread, continue your musings here:

Finally solved the WLAN problem! It seems the Belkin N+ router is not fully compatible with the Galaxy S2. Bought the Asus RT-N56U router a few days ago, and the Wlan - Wifi connection to the phone has worked flawlessly since then!
So now you know!

Yup noobs shouldn't be able to make threads...only replies on posts for a at least a year. Saves a lot of junk. Plus we get a variety of useful threads page after page.

Get off your high horses. I found a solution in this 'noob' thread that I did not find in the pages of waffle on the main thread.
It may have cost me £100 but it is a solution which is what some of us pragmatic types want. The rest of the high and mighty around here can cast around for an understanding of the underlying issue but some just want to get things to work and get on with our lives. Both attitudes are valid and one camp should not set themselves as more 'worthy' than the other.
A sense of superiority is seldom founded on anything useful.

Hello
I got my update a week ago. Never tried to connect for a week. Now I am back at work and my wifi does not work. Worked perfectly before the update.
its a wpa eap enterprise network.
First phase ttls
Second phase pap
It just seems to timeout during authentication. No other errors in logcat.
The GUI seems to have problems too. Even when configured with pap it shows phase 2 as none.
Anybody experience the same problems?
Or does know a solution?
Its the only way to get internet

Same issue here, exact steps. worked flawless before update and now its broken. Wondering if anyone of you found solution on this?
Did anyone tried Acer's wifi patch for this?
Thanks

Just tried steps from following link and seems to be working fine. Only issue is it cant automatically connect to network but once I switch Wifi Off and On again, it connects. Hopefully should work for others too.

I think there is more information on this problem here:
http://forum.xda-developers.com/showthread.php?t=1185885
It seems that WiFi Advanced Configuration Editor in the Market might help. I haven't had time to try yet.
exact same problem. it was working fine before this last update. i am right now on 10.38 com gen1.
The only thing I found is to set the IP setings to static in the wifi network options. It seems to work for now but am expecting a fix from acer.
I had this same issue(PEAP). I was able to connect via Add WiFi network. That was last week. Now when I boot my device in the office. It automatically connects.

The fix on the acertabletforum link did the trick, this has been driving me crazy for a few days. I already had an RMA from Acer and was ready to ship it back, but it's good now....
Just finished a chat session with Acer, told me it was the responsibility of my router's manufacturer, not theirs. They take no responsibility for the problem. Don't expect a patch from them. It looks like I will return the tab, pay extra for sound customer service
On the other hand, just spoke to dlink, downloaded updated firmware, works perfectlyfor two days. While acer was correct their communication to me lacked clarity. I still believe they carry some respnsibility to make their software compatable with a variety of routers. But for me the problem is solved.

Just do a full rom update to Acer_A500_4.010.42_COM_GEN1
http://forum.xda-developers.com/showthread.php?t=1113878
I had the exact same problem at work and started the XDA thread posted ealier in this thread but I was able to find an easy solution. Use WiFi Advanced Connection Editor from the market, load it up, choose the SSID of the WAP and then go to Enterprise Security and re-enter your password. Should work fine from there on out. I'm guessing it's an error with the way the WPA_SUPPLICANT file is storing the data for the WAP.
These instructions are from memory but should be close enough to find your way.

We have 3 SGS2 at home and a Billion 7800N modem
There is a recurring problem on my wifes phone where there is no dataflow. I cant even reach the modem. It will just start working all the sudden for a short period then stop again.
Things I have tried.
1. Using it right next to the router
2. have tried using different channel
3. have reset modem
4. made sure sleep policy is on never
5. Update firmware and hard reset phone - no new apps installed - worked at first but now having problems again.
It never loses wifi connectivity....internet just does not work. Turn 3g on...works fine.
What could be the problem?
Only things I can think of
1. Faulty phone
2. Virus? That phone is sometimes used to check out Chinese websites...and I know some of them can be dodgy. I forgot to ask her not to go to any of those sites after the hard reset as trial and error.
3. Not certain but this problem may only started when we updated to 2.3.4.
If need be Ill hard reset AGAIN when XXKG6 is out - I dont want to flash back to 2.3.3 to try

I have the impression, that the Broadcom WiFi drivers of Android are still buggy, because my Asus Transformer's WiFi also isn't very good.
When using a static IP address and setting Google's free DNS 8.8.8.8 as a secondary DNS server (the router as primary), my SGS2's WiFi works best.
Maybe give it a try.
I have the exact setup and tried all the things you mentioned to no avail. It works sporadically after I reset the phone wifi on and off but it won't maintain data connection for long. Although the signal indicator says it is still connected. the billion 7800 works on my wifes sgs and connects without problem to my work htc legend.

If you google for "galaxy s2 wifi no internet", you'll find out, that several SGS2 owners have exactly the same problem.
I all cases it seems to be the router's firmware, that causes this problem. I found two users reporting, that the only solution was to download a new firmware from ...
http://dd-wrt.com
But maybe it helps to drop the speed from 802.11 N to G?
I have the exact same problem and my firmwire on my router is the latest. What I do to fix this problem is just unplug my router and plug it back in. I find that fixes it for me. Post back if that doesn't work

That's why two guys reported, that they had to download a new FW from DD-WRT, which solved the problem for them.
Sorry, that I don't post links ... it were german forums.
I have the exact same problem. You say that the other two S2's work perfectly? If that's the case then it must be a hardware fault. I'm gonna take mine to be fixed or replaced.

Likely ... maybe different firmware?
Yes....my SGS2 and my brothers work fine. When I update....I update all 3 so we are all using the same firmware.
Thats why I believe its a problem specific to 1 phone....not the router (although I did update my router to latest firmware just in case.....same problem)
As a side note - my brother has a microphone echo problem when using a specific gel case. When my wife and I use the exact same case - no problem. I dont know how Samsung build their phones - but its not very consistent.

That's why we have a thread about the "Made in ..."
But that's not only a Samsung problem ... I know that from the Asus Transformer forum.
Ill see where our phones are made if I have time. If anything though, my brother should be the odd 1 out as his was bought in Australia whereas I got the other 2 from UK.
Ill get to the bottom of this....even if I have to keep doing hard reset and trial and error tests. Not being able to use wifi is a huge deal.
Just to confirm, the problem's not only apparent in 2.3.4. My phone has the same problem with 2.3.3. I've sent my phone in for repair now so i'll post my findings here in a week or so. Have you got any further with it?
I sure hope they do fix it somehow....It's becoming increasingly annoying having to flick wifi on and off, downloading apps is the worst. This never happened on mine or my girlfriends htc's.
Anyone able to find a solution for this problem? Just picked up my Galaxy S2 and have the exact same issue Wifi connects, surf the net for about 10 sec, then nothing.. still connected to Wifi and everything.
At work at the moment so can't really play around with the router settings but will try once I get home. Have been looking forward to getting this phone for a while now and to have Wifi issues right off the bat is quite disappointing..
wifi connected no data flow
i had the same problem
i tried different ways no sucess
i tried Set DNS Pro from market
tried different settings
applied different dns
shift from open , custom to google ang keep checking the internet in browser
after few try it works everytime
its to do with assigning ip address in android
thanks
I posted a solution a few weeks back....but i think most people overlooked it....so the solution is
Go to settings>>>>wireless and networks>>>>>wifi settings>>>>hit menu and go to advanced>>>>regulatory domain>>>>change the channel to 14.....thts it....it worked for me on vibrant,nexus one and even on sgs2..hope this helps

Channel 14 is not allowed in most countries ... my german router e.g. doesn't have channel 14, only 1-13.
I had similar issues with my Asus Transformer and found out, that a static IP works best, BUT only if a secondary DNS is assigned too. I used Google's 8.8.8.8
Give it a try. The Broadcom drivers seem to have a bug, when no secondary DNS is assigned.
The "regulatory domain" setting isn't there on my galaxy s2 ;/ Will give the static IP solution a try.

thx mate ..... this worked for me
I have the same problem currently on 2.3.4 (KH3) and I also had it on 2.3.3 (KF3).
I currently can't find the Regulatory Domain setting.
After an hour on the device it simply forgets it's connected. Even if I'm watching a movie it will stop aND say no connection. I've returned it once so I think it is software vs hardware. Anyone else?

Yeah mine does that also, not my fave, but I just turn the wifi off and then back on again. Sometimes it only stays on the wifi for 10 minutes! Hope there is a fix at some point.

Seems like a Samsung issue....
Looks like all along the Galaxy lineup there are wifi issues.
I tried everything, preventing wifi from sleeping, using wifi fixer, nothing seems to work.
Sometimes my wifi will stay connected, the upload will work, but I get no download.
Rebooting wifi on quick toggle seems to only do the trick.
Have you all updated the software?

Yep, seems to do it more often with a 5Ghz connection than 2.4 though.
None of my other 5Ghz devices (3 iPhones and an iPad) drop wifi.
Signal is on clearest channel available.
Pretty much isolated everything outside of this tablet.
I'm pretty techy with my home networking, so I'm at a loss with this one.
Yes, it has been updated and yes it has occurred on my home wifi, my work wifi, my doctor's office wifi, and unfortunately the hospital's wifi. All with the same outcome! My S5 doesn't do it nor did my S4 running Kit Kat.
So, still no fixes for this! As a previous poster now it is getting where if I'm playing a game it will drop after 10 minutes! I have power save off everything. While hitting the WIFI on off button works it is highly annoying! I want my WIFI all the time not when my tablet thinks I should!

Think I have a solution http://tinyurl.com/nfbgxds
Hope 5th is will help out so far so good for me!
I just got this tab 4 7 inch last week and I am having the same problem with connections showing connected but not having any data transfer. The steps in the above link did not help for me.
I have updated to the latest firmware posted on sammobile, both the Canada version and the nook (BNN) version. Neither have made a difference.
I have found another thread in thisnforrum for this same problem, and there wasn't any solution there either.
I did find wha I think might be solution but haven't proofed it yet. in the build prop there was two "ro.carrier" lines. I think there is only supposed to be one, so I commented out one.
Original Example:
ro.carrier=wifi only
ro.carrier=unknown
Changed example:
ro.carrier=wifi only
#ro.carrier=unknown
If anybody can confirm this makes a difference or not please post results
EDIT::
After two weeks without problem anymore it appears the fix was the static IP address not the build prop change.
I found threads going back to at least 2007 about Samsung devices having trouble with dhcp and all the solutions being manually assign a static IP to the device.
Same issue here. Sometimes I have to cycle the WiFi every webpage!
Both of the above solutions didn't work for me, unfortunately.
Edit: Okay, I may have found the issue, at least for me. Turns out, the tablet was auto-assigning the same IP as my RasPi. After setting a static IP, everything looks okay from here. Hope this helps!
Changing to static IP did nothing, I was having to reset wifi on the tab every time I turned on the screen.
I even had wifi fixer constantly running.
Finally updated to NJ3 and everything is working properly.
Looks like it's a FW issue.

It should be one line:
ro.carrier=wifi-only
Script can be added however by attacting to the rom on the correct line parameters and scripting for digital on board configuration (no smart card) QMAL gsm, gprs, 3g, 4g, even lte or 5g, or 6g, no sim card required researve slot for world phone, or dual networking. The problem is each phone has to be separately programmed so cell companiesnhave walked away from needing higher qualified employees by switching to smart cards. Cost way less and employes way less people and note, your phone didnt cost you a penny less. I been doing cell phone tweaking since the motorolla brick was cool. Currently I used Samsung Galaxy Note 8010 64-bit 32 gig converted to XAC (its the industry's mobile payment recieveing device you see at bars, its made from the model previous mentioned)[to-wit-it says on their site not to tell anyone about]-or else- build then added Debian, Jessie. Then switched the imei to XAC, installed the telephony.manager.is_network_roaming=true along with the prpper scripting for the support and am hooked up to Sask-Tell. Once I got it connected and registered so it had a sign in address with the system i swutched the imei to all 000000000000's now they dont even send me a bill. But it works. The guy at the phone company couldnt even tell me where i was calling him from and he said my phone was disconnected while I was on the phone with him from the disconnected number. lmfao have a good day.
Just wanted to share my personal experience in hope it will help someone else out there as well.
Problems with wi-fi appeared on my rooted N9005 out of the blue.
"Your wi-fi connection is unstable" message followed by complete halt of wi-fi. I read the forums, tried this and that, different firmwares - nothing. Annoying as it was, I gave up on the matter as it was impossible for me to solve at the time. The only band-aid was resetting my router and restarting my Note 3. Then it would work only for a limited time, until when it just wouldn't work anymore.
As a desperate move I tried disabling my AdBlock Plus app. And then a truly wtf moment - everything started working flawlessly. My wi-fi connection is rock solid. :silly:
Well, it didn't seem obvious to me, but then again I AM a newbie. Perhaps you android veterans already had this app on your radar. But listing through forums I never once encountered this as a possible fix, hence I'm sharing this here.
Hopefully it will do the trick for some of you.
Best of luck.
