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!

GUys, i'm having the same problem on my SGS2 as well, check my thread for details, i've attached the logcat in it

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....

ive searched xda for a couple of days, ive googled, ive youtubed. and nothing has helped. seems like not many people are having this problem. but i recently got a galaxy s2 i777. stock GB firmware. stock everything. everything on it worked fine all connections and all the other good stuff. the only problem is when i try to charge it via wall charger it automatically shuts off and flashes the battery charging over and over again. (btw when i plugged in i CAN boot into download mode) same thing happens when plugged via usb. So i got tired and i odined flashed ICS because i read that would fix many bugs.. to my surprise it fixed the battery flashing issue and now when its off and plugged in it charges like it normally would but i CANNOT boot up when its connected to any power source. and even on ICS it still shuts itself off when plugged in. i need to know how i can get it to stay turned on when charging.
sorry if its a little long guys. i hope you can help me solve this problem, and to the ones that are gonna ask why i started a new thread just for this.. well because no one else seems to be having my specific problem. tThank you guys so much in advance for your help
Are you using an after market battery? If yes, try swapping it out with a factory one

Stock sgs2 att batteries?
(⊙＿⊙)
Sounds like the battery is the problem. Make sure the battery you have is NFC. Immediately under the Samsung logo at the top on both sides, it should say Near Field Communication.
The other option of course is to try flashing a different Rom and kernel and see if the problem persists. But they're most likely correct, you'll probably need a new stock battery. Some phones you can use a battery bought from anywhere, our phones are just kinda temperamental. Most likely because of the NFC capability but that's just a guess.

When using a stock Sammy Rom you need a stock battery w/NFC. A Aokp/Cm9 can sometimes use an after market battery. I found that out after buying one without NFC and it did what you describe. Right now I am running Task AOKP with non NFC batt and everything is fine.

Problem??? Because it drops to 99% after you unplug the charger??? That's way within the tolerances of the charge circuit. The real question is what kind of battery life are you getting?
FWIW, My stock T-Mobile SGS-III (i.e. dual core Snapdragon S4) often displays 99% when I unplug the charger. However, it's inconsequential as I get a full day of service from this battery

Well thank you man i thought i was the only one having this problem but fortunatly my phones can last a full and sometimes more than a day.Have a nice day.
Mine still stays on 100% approx an hour later. I.use to have that problem, u need to use different kernel like phenomenal 2.0 or siyah 1.5 beta3
Sent from my GT-I9300 using Tapatalk 2
Weird
Hmm that's weird, cause mine doesn't jump to 99% when i unplug charger (on stock firmware)
What firmware are you using now ?
If I were to unplug my phone and not touch it or wake it up it would be on 100% for 1.5 hours.
samsung made it like this to prevent overcharging well it was on S2
Happens to me as well, i've assumed it's just the battery fuel gage calibration being a bit off, and that's likely what it really is. This doesn't really matter, the fuel gage isn't very precise anyway, by design, so who cares.
This is not a problem.
The battery meter is reset everytime your phone charges to 100%.
Unplugged and checked an hour later and still at 100%...stock non rooted.
Sent from my SGH-T999 using xda app-developers app
Its supposed to do that to prevent overcharging or so I've heard but if you leave it plugged in for quite a while, it should stick at 100%.
Mine used to display 99%, but since a recent OTA update, it now stays on 100% once unplugged. Samsung must have altered it. Im on Stock Rom.

I think you have a problem with your charger port (please do correct me if i'm wrong.). It did happened to me but after a month It just wore off. I mean, it's suddenly fixed by itself.

Please don't underestimate your problem dude.
I am facing the same problem now,
But my situation is worse. I suggest
you immideatly reset your counter,
remove the triangle, unroot your phone by flashing the original firmware and send it to service for repair.
Think about it, after some weeks, if you let it like this you will want to send it to repair but you can't connect it to odin on PC because of damaged usb-port. So they will know that you have been rooted and you will lose you warranty.
That is the problem I am facing now....

I think not. When I was using Litening Rom, I've experienced this. But I when changed to RR, it also gave me the blinking image of the battery percentage. And then one day, it magically vanished like it was fixed. Try using other USB cable. I tried using my moms' and I never saw it again.
hi, thks for replying me , appreciate tht a lot, well, when the battery was charging by it self , i went to cwm and made wipe battery state, and it was gone, ! 2 days and nothing happend, ouuf! hope it will never happen to me or others! see u guysssssssssssssssss

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.

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
