I have a i9300 international and since i upgraded from 4.0.4 to 4.1.1 i`m having problems with wifi. It keeps disconecting from router every 5 minutes and automatically reconects. I tryed everything from disabling things in advanced wifi to disable power save mode in *#0011# menu, keeping it ON allways. Than i changed the router, i modified settings in the router, disabled wifi security. Nothing works, every now and than (sometimes every 5 minutes) the wifi starts disconecting and reconecting in 2-3 seconds. It is verry frustrating. Is there any fix? Real fix?
Backup data and factory reset .
fails flash new firmware .

Ok, but it sucks cuz i have to format everything.
I agree with JJ.. Let us know how it goes
I've installed the custom rom Revolution HD 16 with 4.1.2 in it and it works great now. Done a full wipe, installed the rom and then deleted the cache and dalvik again. That was all, hope to never have that problem again. Oh, and the phone is more snappy too

Hoping someone can help me out... My phone wont connect to my wifi at home (only place I use wifi). It gets hung up on "Obtaining IP Address" every now and then it will also show "Connecting, authenticating, not in range" but always comes back to obtaining IP address and never connects. I first noticed this after I had switched ROMs this past weekend. Went from MIUI to JTs VGB V7... Switched back to MIUI to see if it would fix it and nothing ( Always wiping cache, Dalvik, data in between) Have a tried a few other ROMs since and still getting the same problem... Flashed back to stock this morning and still cant connect to my wifi... I know its not my wifi because I am using it right now on my laptop... My wifes phone can connect without a problem (her phone is on PWGB v2). Anyone have any suggestions??
Thanks in advance!!
I don't know if the modem has anything to do with wifi connectivity but if your wife's phone has no issues on pwgb its worth looking into...what modem are you on versus her? Are they both on the same one?
Also have you tried just deleting your network and re setting it up?
Toggling wifi on/off, airplane mode on/off...not even sure any of those will make a difference just trying to figure out why your phone won't connect but your wife's phone will?

Yeah its pretty weird... We are both on the same modem, EC09. I have tried just about everything.
I had the same problem once. I re-downloaded the rom and kernel in the computer, put them in the sd card then, wipe data and cache and flash it without restoring any backups. That did the trick for me.
Kernel might have borked the IPtables. wipe caches and reflash the kernel.
i installed cyanogen 7.2( the newest ) on my galaxy 5 i5500
but i turn on the wifi, it will auto close(the wifi is on but there is no wifi icon on the status bar and cannot browsing internet anymore, it is needed to restart the wifi(close and open again)) after i locked(blackscreen) about 5min
it is a big problem when i downloading some apps from market (my line is slow about 40kb/s only) therefore i needed to wait it but it is auto close.....
hope u understand what i m saying, because my english is bad and i m from malaysia
If you have the problem only when you have installed the cyano rom, try to do a wipe data and a wipe cache and re-flash the phone with the cyano, remember to install also the latest hotfix for the version that you have.
I have the same problem with official I5503TTLPJP9 ROM (Telstra).
Need to switch WIFI off and on again every time I need Internet access. So annoying!
i have the same problem it is so annoyig
Same here
I'm getting the same WIFI problem here, except that if I'm downloading something, it won´t turn off. But if I lock the screen and leave it alone, WIFI won´t come back on until I turn it off and on again.
I'm using CyanogenMod 7.2.0-RC0 v1.9.
Any hints?
I have the problem that it just shuts down without any reason
as far as i know.
if you go on lockscreen for a while it shuts down too.
but try downloading "blade wifi fix" from the android market.
it might help. because it auto refreshes your wifi
when it shuts down with some reasons in particular.
first thing to try when you encountered those kind of issues is Wipe wipe wipe wipe..
only when you already did it you could try to ask forums for help..
The new WPA-Supplicant download could solve this?
So I installed the latest firmware KPQ and wiped data and cache. Everything is working fine with on exception. When I turn on Wi-Fi, only sometimes it stalls and the Wi-Fi icon in the notification bar is stuck at the "turning on" mode.
I do not know what causes this as there is no pattern to when it happens, if just seems to happen randomly. The worst part is when this happens, if I lock my phone, it will not turn on! I have to remove the battery in order for it to work. This is a HUGE annoyance as when I remove the battery my battery percentage usually drops quite a bit.
Like I said, I have the stock firmware (not rooted) and cleared all data and cache prior to and after installing the rom. The issue is random and has only happened three times since the day the rom came out. Which I guess would be about a week.
Anyone have any information on a fix for this? I haven't found anything on this forum or searching google on this subject...
I also have the same problem. I'm on stock XXLPQ (rooted).
First step is backup data and factory reset phone .
Second is reinstall firmware .
How did you install KPQ ??
K is so last year .

I wiped everything from my phone. Then I flashed via Odin. Then I wiped again.
Hello awesome people
I`ve been looking for people with the same problem as me, but my problem seems to be opposite of everybody elses...
I have been using GoLauncher for a while, but decided to try apex, since i think golauncher has gotten to much bloatware lately. also decided to try a new sms program called Pansi, then the fun started... I tried to send an mms with pandi and the phone for the first time in a month rebooted... then after the boot, the phone suddenly started go into a freezelock everytime the screensaver came on, sometimes i could use the power on button to get the phone to restart or shut down. and after a while i could not get past the pin code screen, so i did a factory reset, installed the lastest official update, phone booted and everything was appearing ok, but no... Did some searching and found out that some that was having the same problem used the "#*0011* and select wifi and turn the power saver off. So no I got rid of the freezelock, but my wifi is all stupid, and disconnects me all the time saying that there is a poor connection even though the signal strenght is excellent. If i turn power saving mode on, the wifi works great, but the phone will freeze on screen unlock
I also used the Toolkit from Mark Skippen to root and maybe the fix was there but still problems, any help would be appreciated...
/chrtn
tl;dr
phone freeze with wifi power saving mode on
wifi not working when wifi powersaving mode off

Hi, I think i've got the same issue.
I had the i9300XXLH1 stock rom (no problem so far)
But then I used the mskip's Toolkit to root it (insecure ALE8 Kernel + CWM Touch recovery)
Then the wifi problems starts :
If wifi is on and connected to an AP -> ok
if wifi is on but not connected -> freezelock (be patient and the touchscreen will come back)
sometimes i can't get wifi working at all...
Any idea ?
Use CF (chainfire) root. It won't mess with the kernel that is supposed to go with the latest rom. Now you are using old kernel with new rom.
Hope this helps
Thank you, will try a factory reset full wipe and try again with chainfire

Hi, I'm having a curious problem with my S3 and I've been unable to solve it. I watched the "noob" video and tried searching these forums as well as a google search with various combinations of the wording for my problem. Nothing matching my issue turned up, I hope I didn't miss anything.
I recently bought a S3 second hand (yes, i know, i should have known better). It was rooted and running some kind of custom ROM when I first turned it on, but I was willing to deal with it until I double checked the procedure for getting it back to stock and starting again myself (nothing against the original rooting and flashing, just like to know exactly what I'm running).
When I purchased the phone I obviously checked that all of the main things worked - calling, texts, mobile data, wi-fi etc. I get home and connect to my home wi-fi and start checking things out and setting stuff up. The phone randomly rebooted. I carry on after the reboot and about 10 mins later, another restart.
To cut a long story short, there is something wrong with the wi-fi. If I turn off wi-fi in the settings menu and reboot, everything works great. No crashes, no reboots. If however I enable the wi-fi about 50% of the time it will crash while wi-fi is activating. The other 50% of the time, it will crash as it goes into the screen lock (either via timeout or pressing the button).
I've re-flashed to it's stock version of Android (using the 'Samsung GS3 Toolkit and Odin), same problem. Anyone got any ideas?
Thanks in advance
You can try updating the modem and RIL to the right version for your country, search in general forum. If it still reboots then try with another wifi source - I've seen some routers cause problems on client machines.
If you do a factory reset when you flash the modem, plus you have the latest stock ROM on board, then any remaining problems are probably hardware.
Test it fully after the factory reset, before you add any apps etc.

After much experimentation and flashing of various files to my phone I have further narrowed the problem. I've still not solved it, but getting closer I feel.
After a clean ROM flash it works like a charm regardless of how much i use the wifi etc. It's only after the first reboot that the trouble starts. It will begin randomly restarting. If I perform a factory reset from recovery mode, it works again, but starts resetting again after a reboot.
Any ideas?
