Hello everyone
I have a Galaxy 2, everything worked great, and one minute for no reason WIFI stopped working, I mean when I turn on the WIFI device starts scanning the network, the scan takes about 20 seconds (of course, no network is) and then the WIFI is turning off by himself.
Besides, everything works, BT,GPS ,also I can get and receive calls correctly.
I Changed for several versions of the modem, dozens of times ,I tried HARD RESET RECOVERY way -- nothing works.
my current state as a pic below
I'd like to accept any idea and help
Thanks all
PLEASE
Please, someone must help urgently
By the way, can it be a hardware problem with only WIFI not working ??

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.

Hello guy's,
I took my phone to the carrier and after lab check they told me that wifi module is move physically on the board -- they say that reason is bad flashing of rom or modem... Does it make sense to someone?? Because i flash just one time in day when i by the phone - and it was work perfect 3 weeks....
wifi module moved physically??
im having the same issue here, will be sending it back to the seller soon
tried almost everything possible solution, nothing works..

Yes, you believe that crap? Their answer was not credible, there is no chance to move physically

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.
SOLVED
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...
lumia 800, 8773.12220 oficial firmware. at home, I connect to internet through my 4GB contract from my mobile supplier. when I turn the internet sharing on, I can connect to internet from my win7 64 bit OS computer via this AP.
I couldnt especially find out when this happens, but the wireless icon in my wireless icon in my notifications (windows task bar) area gets a exclamation mark on it from time to time and after this, my computer cannot go through my mobile to internet. (which is normal from Win7 point of view)
if I turn the internet sharing off and on, I can reconnect to internet until this happens again.
instead, I tried (settings/mobile network) switching to edge and back to 3G, didnt help.
turned the (settings/mobile network) data connection off and on, didnt help.
Is this a know bug, and is there a fix about this?
thanks for replies in advance.
This is a 'feature' of Internet Sharing. It automatically turns off if it is idle for a few minutes (I think it is about 5 minutes). I don't know of any way to change this.

I know that feature. but the problem I tried to explain is not about "auto turn-off if idle for 5 min" issue. this happens while I am connected to the AP and using internet on my computer.
thanks for the reply though.

High power consumption is not a problem since I am using the internet sharing at home, so it will be connected to wall charger. thanks for the solution.
it had same problem with my lumia 710..
try resetting ur device..
it would solve the issue temporarily..
if u are in warranty period please take ur phone to a nokia care..
this is a bug in the software..they would replace the phone for u or get it right

resetting the device works for me as well, at least for a while. device is under warranty, but if its a SW problem as you said, there is no point leaving the device to nokia care for weeks for them to finalise and close the claim. I can wait for the next SW update. on the other hand, even if they give me another device, it will cause me the same problem anyway with the same SW.

does this program increase the amount of data transmitted?
No, it depends on device connected. Of course normal desktop PC would spend more data than other phone
nope... wont help for good. but it helps a little bit, it takes longer to stop sharing with this application. any other suggestions?
Hiya all,
I recently (yesterday) updated my S3 to Jelly Bean via Kies. I'm in UK so we kinda got it late.
Since then however, the Wifi is being a right *****. It keeps dropping and then few seconds go by, reconnects, then a minute goes, then repeats the cycle of hell! I've made sure the power saving mode for Wifi is off by dialling #*0011*.
WTF do I do?
Thanks.
Backup data and factory reset .
jje
Factory reset does not help here. I wipe as a matter of updating the OS (old Windows tech habits) and in-fact it has gotten worse recently. I'd not noticed any problem in the first week but now I see it reconnecting frequently while in use. Often pick it up from the desk to see it wasting my cell data.
It seems to be a known issue, that helps, but not a lot of info so I'll bump this with a reply. Anyone know any more yet? Totally stock system here.
Hi Folks

I also have this problem after upgrading to Jelly Bean. It completely drops for no apparent reason even though it's still says connected and signal is good. I then need to turn the WiFi off then back on to get it working again. I need help getting this problem fixed as soon as possible or I will end up downgrading back to ICS.

Back to the topic, I have the same prob, works after diconnecting/reconnecting, annoying but u get use to it & not that big of a deal IMO, but granted that considering the device's price one shouldn't have to fiddle with it to get that kind of basic option to fully function.

This is a carrier issue that you are experiencing. It can be corrected relatively easy.
If you do not have root access, then root with CF-Root and perform the said modifications and then Un-Root your phone. Simple
Just randomly my phone decided that i no longer wants to work over Wifi. Nothing at all will connect through it but slow mobile data will. The phone hasn't been tampered with other than a new keyboard installed. No root no custom recovery no flashed roms. I would prefer to not factory reset or anything because of apps and personal data on it.
Any ideas will be tested ASAP as well as any questions, answered ASAP
Thanks Weave
Unfortunately the very first step in deciding if your problem is software or hardware is to factory reset and reflash the latest firmware. On an unrooted phone you will lose all your apps and settings, without the ability to back them up or restore them.

Quite a longshot, but- check if your advanced wifi settings is any different from attached

I am coming around to that fact sadly. I have noticed 1 other strange thing. It happened after the router went spastic for a day but its sorted now (roughly a week ago) but the other 2 GS3 I9300's and various computers and other internet capable devices still work fine but when i try connect mine to the Wifi connection it almost seems to kill it, at least for my laptop but i'm not sure of anything else's connection. I don't think it affect them but I cannot confirm that right now. It's cutting connection off to a speed a bit like dial up. Once i turn it off on my phone everything it fine again. Phone software issue I'm going to guess?

I checked and everything matched yours, although i lacked the same number of options. On this phone there is a "Check for internet service" check box but that does not affect it on the other 2 working GS3's.
I am currently experiencing horribly low wifi reception. Sitting right next to the router the signal jumps from full to low randomly and it doesn't catch any wifi in spots where my other devices do. What do I do? Same happened in 4.3 and 4.4.2.
I already did factory reset, switched from Auto to 2.4GHz and 5GHz bands, same happens (Well, no wifi with 5GHz band.). My router is okay, other devices catch the signal two floors down, while this can't keep it stable right next to it.
Screenshot of me sitting right next to the router.

I'm seeing the same problem. As much as I love the design, both the Wi-Fi and Cell reception are the worst I've ever had on a phone. HORRIBLE.
could be any number of issues. each persons environment is different.
i have a linksys wrt 1900 AC router and I use all 5ghz devices and the one max works wonderfully on the 5ghz spectrum.
could be an issue with your radio in the phone itself. im stock non rooted latest update.
The cell reply is great, I have nothing to say about it. However, I took it to the dealer and they'll change the wifi chip, we'll see how it'll go.

Do you have any (good) news from your dealer ? I have the same problem as snapz54. WiFi speed is about 10x slower than my 10 cm distant laptop when I'm not really close to my AP and EDGE/3G/HSDPA/4G data works well only 1 min if I'm in luck when i reset my connection (airplane mode on/off). The rest of the time, well... See joigned screenshot...
I tried stock 4.3, 4.4.2 Sense 5.5 & 6/CM/PAC/NuSense ROMs with stock/FlyKernel/built-in kernels and 4T.21.3218.31_10.16.1718.01L (3.15.1540.1) / ?Don't remember? (3.14.707.3) radios with no luck.
Now I'm running out of ideas...

There is no widespread WiFi problem. Its a very small percentage. Each unit may be different as with any electronic device.

Got my HTC back. They fixed it, but flashed a different, Asian region (default language was chinese, many weird apps installed by default),ROM. Now I want to flash a stock ROM with no weird apps pre-installed and no weird languages. Is there a way to do this? The only thing I could think of is flash Cyanogenmod, then back to stock. Just where can I find stock HTC roms? There's nothing like Sammobile for HTC :l

Its a way to go back to stock. Check the ruu for your carrier in the android dev section. Or perhaps original dev section can't remember which one.

Right, now I am in trouble. Flashed ROM, forgot to wipe data (maybe it does have to do somehing with the problem.), booted, got decryption password because of "unable to mount /data". Went back to recovery and restored my old stock ROM. However, decryption screen still persists, leaving me able to use lockscreen only. The problem is that this rom has USB debugging off and Fast Boot on and I can't change that because of the password requirement, so I can't use ADB or boot into recovery using keys. What do I do to get into recovery?

Hold volume down while phone is booting. Should do the trick. That will get you into fastboot which allows you to get into recovery.
Holding Vol Up + Vol Down + Power while phone was on did the trick, as it restarted and while it was resarting I did Vol Down + Power and voila, problem solved.
