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!
im also having exact problem as defined by op...tried almost every thing.. fw update,hard rest, 2.3.5,etc...no use

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.

I'm a total newbie so please bear with me. I have a problem where whenever I reboot or after several hours I will have no service and won't be able to connect to my network operator. I have searched around and tried various things to try fix this but the only solution I've found is only temporary which is to put my SIM card into my old phone and then place it back into my GS2 which will give me a signal for several hours before it drops again.
I'm thinking it's probably a hardware problem but I wanted to see what you guys have to say.
Thanks,
I actually have a problem that sounds like it. When I leave my phone charging a long time and reboot it with the charger connected, it doesn't have service; the same happens when i turn it off and leave it charging, then (whithout disconnecting the charger) I turn it on.
Isn't it your case?
Are you running a custom rom? It could be your modem.
I was initially on CM9 and flashed Resurrection remix to see if that was the problem. I also tried flashing a new modem but I'm still getting the same problem but this was only recently and I've read that I should wait for a few days to see how well the modem works? Also since then, I haven't seen the error while running only, after I've reboot.
I've flashed a few modems and the problem still persists.
hello ever sense i left my phone on the ground for exactly 10 sec the WiFi has not been working at all, no matter what i try it wont work i have tried factory reset, *#*#526#*#* and the problem is not my router. every time i press on 'turn on WiFi' under it says error and occasionally it will open but of course when it scans for a network nothing will show up. my home network works with other devices. ever since this happened my phones battery life increased do much. if you can please help me fix this issue because warranty is not an option.
i will add photos later today.
Hi, please refer to 2nd guide in my signature and add as much info as possible. Also how is the fact about leaving your phone on the ground for exactly 10 secs related to your issue? You dropped it there or what?

Sorry for not being clear, the 10 sec is when the problem started accruing. I didn’t drop it I just put it down while doing something else. I am currently not rooted, the model is i9100G. I am not using a rom I am on stock ICS
Hi guys,
I wanted to post this in the development thread but since I'm new in here this wouldn't happen
So, here's the problem - my Samsung I9100 phone loses signal and cannot reconnect to the network unless rebooted. You can see the kernel and ROM state from the screenshot.
Every now and then the phone loses signal and unsuccessfully tries to reconnect to the network. I cannot make outgoing calls but am able to receive incoming (but only sometimes, in some cases it wouldn't receive incoming neither). Only a reboot solves the issue but this loss of signal happens at least several times a day and this is quite irritating.
Other problem is when the phone is at a state of no signal, it writes some logs in the system partition in \data\logs which quickly take up all the free memory.
I've been using this ROM since v 3.7. I've updated it twice to get to v 3.91. Through all the releases the issue persisted. I haven't had these problems with other ROMs.
I read somewhere in here that this might be a problem with misplaced or worn-out SIM card. So I put the same SIM in my old Nokia phone and tested for several days - no loss of signal observed in that period.
So any help or advise would be appreciated.
Could this be a ROM issue or a hardware problem? Maybe a kernel problem?
Would be glad if more advanced users give some ideas.
That's it for now, if you got any questions regarding the problem or I missed some information let me know.
Cheers!

Have you tried other modem firmwares?
OK, seems like the easiest solution is to just change the modem...
I changed it to XXKI4 from this thread http://forum.xda-developers.com/showthread.php?t=1277593
I'm starting to monitor whether the problem will reoccur.....
Hi have you solved the problem, as I'm having the same problem ?
hi :cyclops:
when I changed the modem to XXKI4 I experienced the same issue almost immediately after reboot....
then I flashed XXLPX (on random), rebooted again. Since then no problems observed, signal strength is high and 3G speeds are OK....
will keep monitoring for several more days and update you on the issue (I'd be really glad if this simple fix solves it )

Hey, having the same issue... Anything new with this modem?
I've got signal lost almost every day, sometimes few times a day, every few days the signal drops and not back (when I'm clicking on 'mobile networks' I've got the message: "insert sim card - insert sim card to access network services") and only reboot fix this problem (airplane does nothing).
Tried to clean the SIM card, the sim housing, Its not happening in specific place...
I know people who have this issue and uses a different ROMs/Kernels/Modems ROOT/NO ROOT...heres a little list:
Im using right now STOCK 4.0.3 LPG, modem: LQ6 with Siyah kernel 3.4.1
Others using other stock 4.0.3 / 4.0.4 with modems: JHLP9, LPS, ...
Someone mention [not here] about lpx modem that fix it...
If someone else tried it would be great if you share.
thanks!
I had this issue and replaced my battery with another genuine original battery which fixed it totally.

Well, sounds weird...I doubt if its the battery... how long you using the new battery? sometimes its just comes and goes....
Signal lost - log screenshot
Ok, I took a screenshot from alogcat at the same time I've lost the signal... (I export the whole log but seems this app is not that smart and its export only after the signal lost so its irrelevant)
At screenshot - only the 'error messages'
Can anyone analyze this error messages? why is it happens?
Suddenly the signal lost sometimes while call sometimes not, at this time I had to reset the device to get the signal back (its happens once per few days), sometimes its lost and back after ~1 minute...
Don't know if this device has a problem (all the problems that i've heard are from this device, no matter what modem each one use) or its something else....
Would like for some help with this log, and the guy who tried the LPX modem - if its works fine now....
Thanks!
no, it doesn't work.
was OK for a few days then the problem started again.
1-2 times a day I have to reboot due to signal loss.
and the irritating part is that while with no signal the battery drains a lot and the don't-know-what-are-these-for logs keep on generating, filling the whole internal memory......
will continue to dig for a solution....

Do you have a roaming enable?
Here I suspect its the reason for losing the signal, maybe its the problem...
Did you tried your SIM with other device (not S2)?

no, roaming is not enabled and I have tried using the SIM on another phone with no problems
one strange thing is that the disconnection happens absolutely random... at first it happened several times a day.. at recent times it is more rarely - every few days.. disconnections are not related to any location or certain conditions of phone usage... simply no idea
soon I will change the ROM (respectively the kernel as well) and see if this continues
Thats weird...a lot of people with other devices have this issue...at first I thought its only on S2 (modem/kernel/hardware) then I thought its a infrastructure issues in our area.... donno mate....

Need help with this also, same issue
posting an update on the situation...
I changed the ROM with full wipe of data as well as internal memory format. Installed the latest 10.1.3 stable ROM from cyanogen - this means different kernel, different radio and a stable ROM.
And it goes on.... if I had money right now I'd just change the phone cos I'm getting sick of this ****
Please HELP

As per experience this is also due to battery getting weak. Monitor the % you get this problem the most. If it arises around tje same % level then its battery. Also check your battery by rotating it on table and note if it rotats easily and there is any bump in the battery

This is fault of efs in most cases.
Try jelly snap rom which i have most stable and see if it resolves the issue
Otherwise search how to repair efs if pissible
