[Q] WiFi connected but not working - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I have a strange problem that i can't seem to find elsewhere, another wifi one. I am connected to wifi and it shows that i'm connected and shows send/receive arrows. When i try to do something that requires wireless it is like i am not connected even though i am. I have had this problem before and a factory reset or 2 (or 3) normally fixes it. this time i can't fix by factory resetting. btw, i am rooted using cyanogen mod version 11.0

You could try flashing a different modem on your phone or update or change the rom. Since it works after a few flashes, we can rule out that this isn't an issue with your router.

i only rooted last week with cyanogen mod. Isn't that changing the rom? it has had problems before and after this. I have a feeling it's hardware.

Just did some more research on i9100s and wifi... seems to be many problems. Could it be the leaky battery on the main board? i would have thought that would have completely disabled wifi but maybe not

I doubt it is a battery problem. What I meant was to update to a newer (snapshot) of CM11 or try a previous version of android (4.4.2 or 4.1.2).

Note that cm10.2 still has issues even though it is deemed 'stable' by cyanogenmod. And please read my signature and please smack that thanks button in the previous post, I'm glad I helped you fixed your problem!

If I were in you I'll try to flash CM11 again and then checking if the problem depended really due to CM11. I did not ever have wifi problems on that rom.
Sometimes could be your modem/router not connected to the net but your S2 do to it...

Defiantely not router as other devices were connected and working. Flashed CM11 the other day. I did sone further research and it appears that whatever controlls the wifi gets corrupted and reflashing the rom fixes this. All good, have a backup now so fixing this problem is now a 10 minute event rather than mindless resetting for an hour.

[Q] WiFi Stuck at "Turning off..."

Ok, so here's the deal.
After I updated my s3 to Jelly Bean, the following problem started to appear:
Sometimes when WiFi turns off either manually or automatically (I have Tasker which turns off WiFi when screen goes off), WiFi gets stuck at "Turning off..." and doesn't react on any actions.
The switcher gets greyed out and I can do nothing about it. The only way to troubleshot it is to restart the device. Once restarted, everything works fine, but, as you already guessed, it works not for too long. =)
It all depends how lucky I'm. Sometimes the phone can work the whole day without causing the glitch, when I'm not that lucky I have to restart the phone a couple of times during the day. <- really annoying.
The phone is rooted with Galaxy S3 Toolkit by flashing an insecure boot image.
I tried to do factory reset but problem still remained.
I have attached a few screenshots as a proof as well as a screenshot showcasing my phone's firmware specs.
Any ideas or help will be appreciated.
I would blame Tasker try uninstalling and test .

Thanks for the reply. But it seems like this is not the problem with Tasker. As I stated in my previous post, I did factory reset my phone and the problem still remained, though no third-party apps were installed other than those that came stock.
I can reproduce the bug very easily: all I need to do is to turn my WiFi on using the icon under notifications bar and then, once it gets turned on, quickly tap the icon again to turn WiFi off. At that point WiFi gets stuck.

What date is your kernel - August ? If you have a late build of JB the stock JB on my S3 had a kernel build from 19th October.
You may need to just flash back a later stock boot image you will retain root.
Fixed things for me - just extract the boot.image from a full stock rom and use the toolkit to create a flashable tar should fix your problem and improve the battery life

Did as you suggested, tested it a bit and everything works like a charm. The problem is gone, plus I now see more RAM in the Task Manager (this was another issue I was thinking about), and the whole phone seems a bit smoother (maybe this is a placebo effect, dunno).
So thank you very much and you have my appreciation.

What rom are you using, i want also to fix this. Thank you
Could this perhaps be brought to attention again please?
How exactly did you fix it and did it involve losing any data?
NVM: Just download and flash Siyah. Probably the easiest fix.

Nope, flashing kernel will no impact your data.

I don't know about Siyah - I simply took a stock kernel, prepared it with the toolkit and flashed it with Odin. This was pretty easy and it worked.
Hope this post helps.

[Q] GPS issue

I noticed about a week ago that my GPS was not locking my location. I‛m on RootBox 4.0, and I've read that others had this issue with the ROM. I tried all the solutions listed in the thread, but nothing solved the problem. My phone shows no satellites in view or in use, even if I leave it for 20mins. Occasionally I get 1 satellite in view but my phone doesn't use it.
I would appreciate any help.
I had the same problem also on rootbox 4.0. I had success with the third fix in the rootbox thread. What isn't listed there, is that after extracting, pasting/replacing and fixing permissions of the gps driver is that a reboot is needed directly after this. Maybe try fix #3 again from the beginning, but reboot after? I get gps lock within 10 seconds if I do that.

I reboot every time I apply a GPS 'fix'. I'll try again though.
Tried again, still no joy.

Alright, so the obvious which may not be so obvious. It took me a while to figure out what was going on but now each flash I can get GPS lock after a few minutes fiddling and 10 seconds waiting for a lock. So we're on the same page, this is what you're doing:
Download and extract attachment. Using Root explorer, backup the gps.exynos.so in system/lib/hw to sdcard, then remove it from the system/lib/hw folder. Also using Root explorer, copy the gps.exynos4.so that you extracted or whatever its called to system/lib/hw. Fix permissions to rw-r--r--. Reboot. Open Google maps, grant it the permission to access location. Wait for GPS fix.
Using those steps I get GPS working first go every time on RootBox 4.0. If I miss anything, or do anything different, it won't work. Are those the exact steps you're using?

Permissions set properly - still not working.

Another captain obvious comment, you are searching for GPS while you're outside? I would assume so. Have you tried re-downloading the file for the fix from the RB thread? If you haven't, try that. If you have, reflash the ROM after a factory reset, cache & dalvik wipe. Try to fix the GPS before restoring all your data etc.

Does this mean anything? One satellite keeps popping up in the centre of the radar.

Couldn't tell you sorry. Not sure what app that is/what it's meant to do. To test my GPS I use Google maps.
Edit: did you reflash the rom?

Omega AOKP has written in the OP 'instantaneous GPS lock'. I've used it and had no issues with GPS at all, give it a shot.

I've restored an old backup of resurrection remix, and I still have the problem.
Is it possible that some system files regarding the GPS were corrupted?
So when you had resurrection remix previously, did you have working GPS? And did you try omega? Next step is to flash stock after a full wipe. Stay away from 4.0.4, but pick yourself an ICS/JB ROM and try it. If the problem still persists, then it's possibly hardware. Either that or something is messing up with each flash, which is doubtful.

I doubt that this is a hardware issue. A week ago I was able to get a GPS lock if I waited for 10 mins or so. I started applying all these patches and fixes in an effort to get a decent lock time. After messing around with all these fixes, I have now ended up with no satellites in view and no lock, no matter how long I wait. Therefore, I believe that I've messed up some sort of file whilst trying to reduce the GPS lock time which has now stopped it from working completely. Oh yeah and btw, I was able to use gps back when I had RR ROM.

Two words: Flash Stock.
Flashed stock - problem still persists.
UPDATE - finally got it working. Flashed latest stock firmware; it didn't work at first, however after persistent testing I finally get a lock after 26 seconds or so.
Thanks very much for all the help.
Hardware problem. Service centre (Unless you want to try all the usual fixes you'd try if you were still running a custom rom, which I very much recommend you do first).

Can't find WIFI

Hi guys
My phone was running great until i bumped into this problem. It seems like my phone can't detect any wifi anymore, the list is empy when im in the wifi settings. i've tried to factory/hard reset my phone but the problem is still there, i've also tried mega wipe but that did not make any difference.
There is nothing wrong with my router beacause i have other phones connected to it. I tried to connect to wifi at my friends home but still, no wifi :/

maybe try a different kernel and see if flashing it fixes that. Or could it be that you switched the Wifi settings somehow to only detect wifi networks in a certain m/ghz range 2.x vs. 5?

Then flash your original rom .

maybe you need to flash a new modem. ask someone in the 242 who has a i9100 what modem they are on *#1234# to check and flash that modem.

I have tried different builds higher than 6 and same thing happens. Installs fine and have service for 2-3mins then off again. This is frustrating because after that then i have to reinstall the same old ROM and reinstall all over again. I've tried 4.3.build.1-OFFICIAL-909 thinking that maybe if i change from 4.2.2 this would solve my issue but still the same thing.

Is there a fix for this ?

It's probably a problem with the rom, so you can't do much about it unless you change roms or try older versions.
