I'm not exactly sure when the wifi stopped connecting to any external devices (since I don't really use it) but I was just curious if anyone else has had the same problem.
Basically it will pickup routers/whatever, notify, ask for pass key (if needed) and then try to connect for about 3-4 seconds, then just say unavailable.
I can get multiple connections popping up for wifi nets in different physical areas to connect to etc, but they all do the same thing. It's been about a year I believe since I could connect to anything. Wouldn't mind using this at school.
If this has been answered, oooooops. I'm sorry guys but there were just too many noob posts to look through while searching for this.. Sorry folks, peace!
btw i've went through dozens of roms over the time period all same outcome, problem internally somehow perhaps?
I believe I saw you post that you are now on XPlore 2.0. If you still don't have WiFi then you have hardware issues.
i think some roms have a problem with either wpa or wep security
sweet
yes I havent been around much anymore, nor updated my stuff. It's all good, no biggy, I gotta let the wizard go in a couple months was just curious. Thanks all!
I just want to know has anyone had any problems with the wifi? and wep/wpa? ive heard some complaints about this and i jus want to see how common it is
I use mine on a wep and wpa network everyday with no problems at all.
I use wep at home and wpa at work, no problems.
no problems so far...

mines also good too.
Wifi on mine is 100% broken. Trying to turn it on makes the phone freeze and then reboot.
Phone arrived yesterday. Wifi never worked a single time, out of the box. Details / video below:

Buyer beware.
Ok thanks guys, it seems only a few are broken, fingers crossed I guess.
Paul has another, much larger post about this up here somewhere that you can probably pitch into.
I read that rebooting 4-5 times worked for someone. :shrug:

To be fair, I've searched and searched and searched on here, Google's support forums, Google itself, etc, and have not yet found a single other person with broken wifi like on mine.
So I guess I'm 1 in 20,000, sigh.
Either way, I would caution against purchasing the device until the 3G/Edge switching problems have been fixed. I didn't care about those issues, because I thought I'd always be on wifi. Heh, boy was I wrong...
Thanks paul, I do suggest sending it back by the way
No Wifi problems here either WEP or WPA (no 3G/Edge issues either)
WPA works fine here, but doesn't always re-connect automatically after an incoming phone call. Sometimes need to force a re-scan when I'm at the far edges of the range.
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:
http://forum.xda-developers.com/showthread.php?t=1067473
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!

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.

At least give us thread link then close this thread . I am not finding the particular NOOB thread
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.
Hi All,
Since I got my DEFY I have WiFi problems. This issue only exists when WiFI has WPA/WPA2 PSK authorisation.
It is going like this: I connect over the wifi. Then connection works fine, I am able to browse www, check the emails etc, and after few seconds, minutes the connection stops working but still exist. I try to reconnect several times. Defy shows that is connected but nothing works fine. Internet apps or Market gives a message like the time is up, connection lost. I have to forget the conection in settings or reset device to get it working properly, but not for long.
And the thing is that there is only ONE ROM that works fine with WiFi on my DEFY. This is Cyanogenmod-7.1.0-RC1. Other ROMs have same issues. Doesn't mater if it is Cyanogen mod 7.1 stable or any MIUI or MS2Ginger. I tried almost all roms but nothing helped. So I had to go back to CM7.1.0-RC1.
Do you know what should I do to make WiFi working fine on other roms?
greetings,
Gregory
p.s.
Please, just don't tell me that I should change authorisation on WiFi router. This is not a solution for me, because I use WiFi in a lot different places.
Same problem
Hi,
I have the same problem with my Defy since a few months, no solutions!
I have the *EXACT* same issue. Was about to roll back to stock and send it in for repair, glad I found your post! I'll install the ROM you suggested and keep hoping this gets fixed
just fixed my wifi issue for the second time. If there are to many remembered networks no more wifi. You can turn it on but it cant find any. delete all remembered networks and back on line. that is the only conectivity problem I have ever had after months of cm7

I think that's a different problem than we're having. It is finding the network just fine (and connecting) in our case. It's just that internet connectivity refuses to work after a few minutes, forcing us to disconnect-reconnect to get it working again
@OP: Thanks a lot! The ROM you mentioned does indeed not have this problem. It's not as stable as some of the more recent roms though, think I'll still be forced to revert to stock
i had exactly that problem with my first defy, no solution man, i send it to warranty and they give me other
maybe changing the regulatory domain channels from 11 to 14 could help. this option is hidden by default, you have to enable it: change the value of 'ro.debuggable' from 0 to 1 in /system/bootmenu/config/default.prop, save and reboot. after that, the regulatory domain setting will be shown in settings/wireless/wifi/advanced. simply change it to 14 channels.

Thank you for the suggestion! Just tried this, didn't resolve the issue sadly
I'm looking into rolling back to a stock Froyo rom but the information is scattered all over the place, I'm having a hard time figuring out if it's possible, and if so, how ;/
Anyone have any more ideas? ;/

OK, maybe I just passed the signpost but... do you still have the problem if you set your "select network" setting to 3G only?
I ask because (and it may be different on my phone as I am USA, stock ROM with wifi calling) if you go into the INFO menu > phone information > set preferred network type, mine toggles between three radio preferences: "GSM only" (when wifi is active), "GSM auto (prl)" and -- if I set for 3G Only, "WCDMA only".
I have noticed that when "select network" setting is at automatic (or 2G only) it often has trouble transitioning from cell to wifi. And, when wifi is an issue, I find that "GSM auto (prl)" has been selected (which on my USA phone prevents wifi connection). However, it seems to have no issue whatsoever transitioning from "WCDMA only" (3G only) to "GSM only", which on my phone then allows wifi connection. Again, this is a wifi calling phone so may be different.
Yep, same here BUT ! I get root browser, found my build.prop and change wifi chanells first time for 14 and it didnt help so i try other and my wifi works in 100% with 13 chanells. Try it
This is a widely know problem, many people are affected more or less. I'm also having nerve-blowing times with wifi sucking all over... Stock Froyo (and now Cyanogen 7.2) seems to be a bit more stable, sometimes everything is fine for a few hours, all downloads go lightning fast - and then suddenly things are screwed up. I tried a lot of MIUI releases as I like it most. MIUI seemed the most problematic so far. I don't know what is the cause, new stock Motorola Gingerbread ROM versions also have this issue (except one I think - look it up in the forum).
Agree, bothering with the router is not a solution. My Nokia E51, my EeePC, my girlfriend's Omnia and Lifebook - all work perfectly with all the four routers we use frequently. Not a single glitch - everything is stable and nice, except Defy.
I don't think is a hardware problem with certain devices, it seems more to do with the way Defy handles wireless connections.
Anyway, it's frustrating but CM7.2 and CEE Froyo gives a bit better experience than others.

Which Froyo version do you use? A few times this wifi-bug occured also under Froyo. I'm thinking about going back myself, as Froyo is the only acceptable release to record hiccups-free videos
