[Q] Wifi not working - Galaxy S II Q&A, Help & Troubleshooting

Hi all thanks for your help,
Australian user here on virgin.
Basically when I first got the handset I flashed and used villain rom... everything worked fine for a week or two.
Then the wifi just stopped working.. it wouldn't turn on. I would enable it.. it would scan.. scan wouldn't work and the icon would turn off.
and I can't wifi hotspot my 3g connection it just says error.
The problem seemingly went away at random :S:S:S and now has arisen again.
I've tried using batista rom and that didn't help.
Tried searching couldn't find any solutions ((

ok i happen to have this issue last month and i spent 2 damn days to check everything.. but end up it's hardware problem.. you turn on your wifi it will scan a while but then shut off by itself right? if that so i really confirm you need to send back to retail shop.. before that you need to do a nandroid backup and flash back to original rom ( unroot )
trust me man it's the motherboard problem.. check this link for how to unroot..

p.s. you need to buy a usb jig to clear the binary.
hope this help

WiFi is not working

My WiFi is not working when I turn it on. When I turn it on, it just do nothing. I tried to run WLAN Module Test to check the problem using Self Diagnostics, sometimes it can detect the MAC address, means OK, but sometimes it shows error saying "GetAdapterInfo() return FALSE....".
For your info, I already reflash the updated ROM (0426), but it seems not working. Now, I'm using ATOM EXEC ROM (0721).
Can someone please help me before I send my ATOM to repair center?
You sure this isn't after an ActiveSync session? My device often needs a soft reset after a session.
Yeahhh... I'm very very very sure about this! Eventhough I didn't use Activesync, the same problem still happened.
I tried to downgrade the ROM, the WiFi still not working!
I have the same problem as idzilhafis.
Tried to run Self Diagnostic and got the same two answers, sometimes the module is correctly detected and somtimes not.
When the module is detected during the test, also the Access Point name is detected (I have a wifi AP at home), but the connection doesn't work.
When I use Wireless Manager, the module is not alwais detected and sometimes also the wifi button disappears.
Of course I flashed and re-flashed the firmware, using the original manufacturer's latest ROM and the "not for sale" version. Nothing changes.
May be an hardware failure?
I think, I can answer myself.
Yesterday in the evening I did put the Atom in the fridge for a while, because i noticed that using the pda and then increasing its temperature, the module was never recognized.
Using the pda after an hour of fridge (I did put it in a little bag), the wifi module works like a charm. It is ok until it's temperature raise again, then the module hangs.
Such a behaviour is typical of an hardware fault.
I think that this kind of problem is surely not due to a wrong use, and should be covered by warranty. But I don't know where to send it for service (I'm in Italy).
Any idea?
I had tremendous problems with my O2 Atom WIFI which would not connect to my laptop WIFI LAN Network. I asked O2 Technical People & Lot of people on this and other forum but got no perfect response.
Practically trying many options I by chance put back the old ROM upgrade of O2 2006123-45 and tried switching on the WIFI and lo and behold it worked fine.
Then I reload the new ROM 20060426 again and it works fine.
This proves that if you reload the NEW Upgrade ROM more than once it locks the WIFI.
No, it proves that any ROM upgrade can result in strange things, and reflashing either the same ROM or another ROM can fix it. It's well known with stuff like battery use (some users have had their standby time doubled by just reflashing the same ROM).
I sent to o2 expert and he don't know what to do. Tried to change registry, still not working. Tried to reflash, stillnot working. I think hardware problem. Don't worry, I still got warranty!
Hi All, I'm a newbie.
Pls shows me where can I download this oldrom O2 Atom 2006123 (-45)?
Or Who can give it to me through email: [email protected] ?
Help me pls, tks a lot

[help] Can not connect to network

My X10i is Rooted, has Android 2.2 (from Rodeiro) bandversion 2.1.54 and Kernel 2.6.29 Mod version CyanogenMOD 6.1.1-V03
Now I have the problem that i can not connect/register to a network, i can see all the networks but if i want to connect to 1, it just wont happen.
I tried a restore of an old ROM and the problem remains.
What could be the problem ? is my X10 broken ? Coul this be a radio problem ?
Please help, need my phone...
Coop,
Hello!
Is data across mobile network enabled in the phone settings?? Try turning on airplane mode for a minute, then turn it off, brings my network back!!
Best regards,
Chris
That does not seem to help.
I can see all the carriers, but if i want to connect to 1 it wont happen, this message i get :
Registering on Network.
I keep hanging on here, maybe my X10 is broken ?
When did this start?? Any changes to the phone before this happened??
Turn it off and pull the battery for about 5 minutes???

Hi Rendeiro
Indeed, i can see all the networks : T Mobile Orange Base and so on, but if i try to connect to either one of them it wont work.
I disconnected the battery now, hope it works, tryd everything, restored older ROM, installed fresh ROM.
Hope it is not broken, i have no guaranty anymore.
It happened today, was watching footbal on tv, worked fine the other days !

Strange it is !
Anywayz, have to root again and install xrecovery

[Q] Wifi not working after 3588 update

Hey,,
So I received my G tab today and connected it to the internet and downloaded the update (Tap UI V.1.1-3588).
However, after the update got applied, when I try to turn on Wifi it says error. I tried to restart the device twice and on both times the wifi worked and actually connected to my network but then disconnected and went back into displaying the error in matter of seconds. I have searched the forums but it seems no one with stock Rom have had this problem.
Thanks in advance
I had issue with the stock fw, never ever after 3588 was ok, even when reinstalling
Try a new firmware. Maybe

I've got the same issue here. After restart I have Wifi for a couple minutes then it disconnects and errors until the next restart. This is my second G-tab and my first one works great.
P.S. Other ROMS didn't help my condition so you may want to pursue return before attempting Rom upgrade. I'm back to bone stock and still not joy.
It works now !
All what I did is close the wifi as soon as it starts, gave it a minute then turned it on.
Now I'm not sure if I should do this each time i boot it up, but, it works !
Try doing that, maybe it was by chance that it worked with me .

Four day old phone return to the seller under warranty .
If you follow the advice posted above you will lose warranty and a rom cannot fix a possible hardware problem .

The post I pointed to was one where someone had uploaded a WiFi folder.
