I suddenly had a wifi problem. It happened around two weeks ago. I suddenly was not able to connect to my home wifi when I was more than 2 or 3 meter away from my router.
I've had my S3 for a little over two years now. I upgraded to 4.3 early this year. All updates were done OTA here in the Philippines. But this just suddenly happened last week. There were no updates and I can't remember ever downloading a new app that may have caused this.
I have tried absolutely everything:
1. Tried flashing new modems and kernels.
2. Tried flashing CM11 then wifi fix patch - didn't work. I flashed boeffla kernel - it just made it worse, I could connect when I was near the router but couldn't use the internet - it just showed wifi was connected but with slow or no internet.
3. I tried flashing back to stock rom and even updating with kies but still the same problem.
4. I flashed Android Revolution HD v52. Tried different modems on it. Flashed wifi fix. This still didn't work so I tried boeffla again. No luck.
5. I tried the murata fix through terminal emulator and still didn't fix it.
Right now I'm running on Android Rev HD v52. I'm still hoping someone has a way to fix this.
I don't know what to do anymore.
Can anyone help me, please??

If you really tried so much things, maybe your hardware is damaged, the wlan adapter in your smartphone or something
I had a similar thing yesterday, on stock 4.3. It started with the unstable internet messages for a week or so. Then yesterday, it would connect to wifi, but apps saw no internet. Cleaning cache did nothing, forgetting and reacquiring wifi did nothing. Factory reset did nothing. Flashing a different 4.3 did noting. Rolled back to 4.2.2, which used to work fine, and still had the problem. I had given up at this point, figuring it was a hardware problem. Flashed 4.3 again, and miraculously it started working again.
I am really getting pretty fed up with Samsung at this point.

Hi there porusski!
The best thing to do is to take your phone to your seller, Galaxy S2 has a two year warranty. They should fix it or replace your phone, it shouldn't take more than 10 days.

Do you have a Netgear router by any chance, cos they suck balls, and as a general rule, will not connect properly to an Android device.

I was previously using a Huawei router. It kept disconnecting from the internet, so I changed it over to a Netgear DGN3500. I've had nothing but problems connecting the Galaxy S2 to the router over wifi. Keeps going between one bar and no bars, and disconnecting, even I'm not that far away from the router. In order to get 3 bars and a good signal I have to be directly next to the router.
Same issue here
Hi all,
I have the exact same issue, also tried wiping everything and switching rom/kernel/modem, also tried restoring to a nandroid when everything worked perfectly and still wifi doesn't work. I noticed that the wifi services are not running also.
It stopped working gradually after working great for a long time, sometimes I was able to connect sometimes don't, until it stopped working at all.
Do you have any updates on your situation?
Interesting. I seem to be having the same issue. I can connect to the router fine but it wont let me browse or download anything. 3G is working fine.
I will try and swap ROM (again) to see if it solves.

Turns out it was a hardware issue - 2 resistors needed to be replaced

where did you get done?? Im also having the same problem and im frustrated.. pls give me some suggestions...
Hi,
Sometime today I lost my phone signal on my SG2. I'm not sure exactly at what moment as I first noticed that I had a couple of bars but no 3G when I tried to browse the web. So I restarted the phone but to no avail. Since then I've lost all bars and can't make any calls either.
The only thing I have done today "out of the ordinary" was to connect to the phone using Wifi File Explorer to transfer a file, which I tried to connect to without being on a wifi network by first trying the "Wifi Direct settings" in Settings, which didn't work, and then by tethering by Wifi which worked. Maybe some setting got stuck in the process, but I'm not sure since never checked if it worked right before and after.
If anyone has any idea what could be wrong please let me know, as I am literally without a phone!
I recommend downloading http://www.androidzoom.com/android_applications/communication/no-signal-alert-pro_fyyo.html this will definitely be of benefit to you if your suffering from signal problems, it has been of good use to me.
Check your IMEI is the correct one for your phone .If not restore your backed up EFS folder .
Or try backup data and factory reset as a first step.
jje
Thanks for the quick replies!
The IMEI does not correspond to the one I have written down, though I'm not 100% I what have on my note is the latest IMEI; but how could that change though by itself, if my note is correct??
Also, I just saw something very strange: I turned on my phone and had full bars (no 3G though), and right in front of my eyes all bars dropped, one by one, during the course of 5-6 seconds. Something is VERY off...
Regarding factory reset: my phone is rooted (thanks to XDA!) and I have Tit.backup: can I will my phone still be rooted if I do a factory reset?
Something went probably wrong when rooting it (not neccesarily any errors) and effed up tge EFS folder.
Try to flash back to stock ROM, it might work to restore your.folder.

I should have been more clear on that, but I rooted the phone about a month ago and it has worked flawlessly since then, so it couldn't be that.
Anyway, I looked around a little and found this post:
http://androidforums.com/samsung-ga...connectivity-but-no-idea-why.html#post2722784
He seemed to have had the exact same problem that happened to me, so I decided to wait, and sure enough the connection reestablished itself about an hour ago and while I was watching for it, with the signal slowly creeping back up during a couple of minutes, and several hours after I lost it. Very odd.
This surely has to be an Android bug but that only shows up under certain and rare conditions.
To be sure I made a speed test and got 4.84 Mbps/up, 1.19 down, which I guess is fine; I never did one prior to this so I have nothing to compare to.
Again, appreciate the advice!
EDIT: For posterity, I should add that during these hours, even when I briefly apparently had a (non-3G) signal, I had a notification during all this time saying that I could only make emergency call.
I'm having the same issue. No Bars at all most of the time and when I have some, it never connects to 3G, G at most, and can't load any thing at all.
Very frustrating. I have been using Lite'ning rom 6.1 for a few months and had no problems at all until about a week ago.
I flashed back to a stock rom and still having the same issue.
I've also seen the bars drop down one by one in a 5 second window, bizarre!
Anyone find a fix for this? Or could the phone be faulty?

I was on Lite'ning about 3 weeks ago and actually completely lost signal several times. Reboots and hard resets solved the problem temporarily. I then flashed Batista FH 2.4 with ICS and things were great. I'm now on GingerMod. No issues.
I don't know how it could be kernel related though, especially if you are 100% stock again.
Hi,
I have bought Galaxy S2 just two months back. My wifi was working fine until one day it stopped working. When I switch on my wifi, it just scan for the network and then gets off. My other devices are working fine with the router. The same problem exists even after doing a factory setting for the phone and reseting the wifi router at my home.
There are few things worth noticing about the problem:
1) My PC is detecting so many wireless networks around here but my phone wifi detects none because it seems to me that the wifi is not even getting started in my phone ... no wifi notification symbol.
2) On starting other wifi related setting like "wifi direct", my phone hangs and it shows a dialogue to force close it.
Please suggest some solution for the problem.
Thanks.

I recommend to flash the latest stock ROM for your region.
You can find many official firmwares in Intratech's thread => http://forum.xda-developers.com/showthread.php?t=1075278.
Please read the first post carefully.
After flashing the ROM, you should do a hard rest (by dialing *2767*3855# in your phone).
Hope this will help!

Mine have the same issue. Started to force close when in wifi settings and wifi direct. Phone started to hang-up. I tried hard reset few times then it started showing "error" under "turn on wifi". Seems to be a hardware issue. Phone was working fine until yesterday. Going to the service center today. Will get back to you guys. Mine runs 2.3.6 (INU).
Does your phone lights go out when you switch off your phone? If so it is a hardware issue. I had the same problem and had to replace the mainboard. If you reset phone you will see "error" under "Turn on Wifi" option.

Can you please elaborate what you mean about the lights switching off?
I am using Galaxy i9100
android version: 2.3.4
baseband version: I9100XXKG5
When i switch off my phone, it shows the animation, then the screen turns off. but all this while the capacitive buttons (the back key and the menu key) remain lit up and continues to be lit up for 2-3 seconds after the animation is over and then turns off. So do you think my mainboard is gone? I'v had my SGSII since last summer and had wifi problem since 2 days now.
Went to the service center ... Its apparently a mother board problem and they are charging me 9,000 INR to replace it.. Heck, i would buy a new phone with that amount.. Bye bye samsung
There's this thing called warranty....
Sent from the little guy
I got my phone back on Wednesday from the repair people that my insurers use after dropping it last month and shattering the screen inside (fortunately the phone itself still worked properly)
At the time the phone had been dropped, I was having problems with it in that the phone couldn't get a phone signal at all and I was going to fix the problem myself. The repair people knew that it had been jailbroken and I explained that I would fix the problem with the lack of signal myself.
Now, I have a new problem in that every time I get a WiFi signal, it keeps getting disconnected within seconds and I've noticed that the repair people seem to have reactivated the infamous "Flight Mode" problem which seems to have somehow affected the inbuilt WiFi system in that every time the phone manages to detect a signal, whether it's at home or elsewhere, such as university, it loses the signal.
In any case, does anyone have any suggestions on how to fix the problem (I installed the latest VillainROM yesterday which is 3.0) including what modem to use and how to install it?
I would try some different modems and see if you find one that solves your problem. In the first few posts of the VillainRom thread is a link to the thread attachments. Included in there should be a few modems in zip format which you can flash through CWM. Also some of the posters (I think one is geko95gek??) have them in their signatures.
Hope this helps

Hey there, not sure whether this is an ongoing issue, but the problem seems to be related to the embedded kernel from VR 3.0 (Nimphetamine 2.0.5) I was facing exactly the same problem. The only way to fix it was to flash a different kernel (siyah 2.2 in my case) .
I tried all available radios but nothing fixed it, maybe pulser has to take care of it in the next release, so flash another kernel and the problem will be solved, good luck!
Yep, as in above post. WiFi drivers are found in the kernel. Try Siyah, Speedmod etc.

Ive searched the forums, googled, factory reset, messed about with *#0011# power save, rebooted/forgot router and I'm STILL having issues with the wifi dropping and reconnecting periodically (maybe once every 10/20 mins?) . Im on BLG8 which is as far as i can tell the latest firmware (im not rooted) for the UK.
Has anyone got a solution to this? The main reason is I use Skype a lot and the call will just drop (obviously) with the wifi drop outs.
No other device has issues with my wifi router.
Any help would be much appreciated
Cheers
Does it make any difference how far you are from the router? Does it always connect fine initially?
I'm having the same issue and i've tried every fix that has been suggested. I dont understand after spending the amount of money i did on this phone that i have to run through the dialer to get it to work properly sometimes. Then other times it still drops out and wont come back on for 5 to 10 minutes. I've changed roms, kernels, and wiped completely i dont know how many times and went back to stock. Still works sometimes and hangs up others. There doesn't seem to be a permanent fix for people lucky enough to have this issue still. My 30 day return is way up and gone so i cant send it back. Samsung cant seem to give me an answer. I'm at a loss for words.

My 30 days was up, it's still been replaced under warranty. I took it to CPW who sent it away, it came back 'fixed' so I asked them to log into their WiFi... of course, they couldn't and the guy said he would order me a new phone but it would need to come from Samsung. My new one has blazing fast WiFi!
i have the same problem. i was hoping a new rom would fix it, but FWIR its busted. i get 2 bars MAX no matter how far i am from teh router. its fast enough, but it drops out constantly.
also my screen is sometimes slow to turn on from sleep.
im on vodaphone if that makes any difference.
Guys... I had a very similar problem with my phone.
First of all WiFi became very unreliable.. like yours. I changed ROM and it still persisted. I even went completely back to stock.. and it still persisted. Dropping out.. no reliable connection etc etc.
Then it started being really weird.. the touchscreen started responding intermittently. Sometimes I couldn't get it to unlock. And this was all on stock.. no root etc.
I was ready to send it back to be repaired.. and I came to the conclusion that there must be something staying the same.. even after a wipe / reflash. Maybe one of the other partitions was corrupt???
Now I'm not clever enough to investigate.. but I did come to the conclusion that a repartition may wipe everything and make it a real fresh install next time.
So I found an appropriate .pit file and stock ROM and used Odin to flash the ROM and partition the phone.
And it is now all fully functioning again.. no WiFi issues at all.

It seems to have improved with the latest JB leak, still every now and then but certainly better - i did a full factory reset + cache wipe in stock recovery (im unrooted etc). Still, would a modified kernel/modem fix this very common issue?
This problem is everywhere it seems.
OK so really weird update: my screen unlock is still a bit slow, but my wifi hasnt dropped for a few hours. i went through all the vodafone crap and updated/ran/configured it all, and now it seems fine. seemed vodafone wanted to verify my phone+sim details but couldnt over the wifi so kept trying to do it over the 3g, but couldnt do it quickly enough so the wifi cut it back out again. I have a headphone amplifier that is very sensitive to mobile phone signals. it beeps 4 seconds before i get a message or phonecall, and "ticked" at me whenever my wifi dropped out. its not ticked in hours.
TL;DR anyone on vodafone, run your "my vodafone" application and configure it all. might fix it.
Mine drops wireless a lot when connected to wireless A networks. It seems stable on wireless N networks. Anyone else notice A networks to be worse?
