[Q] wifi not connecting - Galaxy S II Q&A, Help & Troubleshooting

HI all
I am not sure if this is just me or this is a bug for the ICS.
I have flashed (do wipe and all that) but my WIFI is not re-connecting.
So I get the WIFI connected first time without issues. then if I turn off my modem and switch it back on, my phone does not want to re-connect. it looks connected but no internet connection. I have switch on and off the wifi but no result.
The only one which will fix it is to reboot my modem again.
I never have this problem with GB.
I have tried LPQ, LPS, LP3 and also LP4 but no sucess. Do I miss something here?
I did a search in the forum but no result on the solution.
Any suggestions on how to fix this?
I don't want to root my phone.
Cheers

I also have this problem. I'm on LP3. No solution for this yet?

Happen to me too before.. and it happen randomly too!
Toggler the wifi few more times..
and/or
Try disable and enable "flight mode"
fix for me..!

Did all that but no luck. I thought it was just me

Wi-Fi & GPS unresponsive

I seem to be having a small(or large?) issue with my Wi-Fi connectivity - after rooting my phone it didn't surprise me that I lost GPS functionality, it didn't surprise me that I never got it back but hey I can live without it if it means I don't have to wait for HTC.
What's beginning to bother me is the fact that my phone can't manage a Wi-Fi connection it could 3 days ago.
Tried restoring my 1st nandroid backup that I made immediately after I flashed the custom recovery and I still had no Wi-Fi. And no GPS.
Also I have tried flashing 63.18.55.06JU_6.35.09.26 as well as 63.18.55.06JU_6.35.08.29 with no result on either front.
Please help me out if ya can.
What ROM you using pal?
1st thing to try is to put both your GPS and WiFi on, then turn your phone off and back on again.
I'm currently trying to use SenseHero 2.2
I have tried turning on both WiFi and GPS and rebooting, I have also tried similarly - leaving them on and flashing the radio too...
It doesn't seem to be helping all too much.
Furthermore(and the part that concerns me most) I have tried restoring my initial nandroid, the 1st one I made and saved after flashing the custom recovery and still nothing.
and there's no mention of issues in the Sensehero thread no?
If I was you,....
I'd backup my sd,... Format it. Then run a RUU so it unroots and goes back to stock state,... then see if it is working again or not.
I've been searching threads over as many forums I can find for DAYS. But still a no go..
I suppose I'll try to unroot it. I haven't finished researching the RUU's, does it matter which one I use?
Well apparently unrooting the phone doesn't reinstate the GPS or WiFi connectivity.... GPS still "unable to determine location" and the WiFi still SEES the WLAN networks in range but still cannot connect to any of them.
I can't seem to find anyone else who has had problems with WiFi connecting let alone wifi AND gps problems.

[Q] Wi-Fi doesn't work in all custom roms! Help me!

So this is the problem. Wifi works ok on my original 2.1 firmware. But it doesn't work on custom roms. Why is that? How can I fix it? Please help me someone/
Hi there
Some additional questions:
1) which custom roms have You tried ?
2) what do You mean by "doesn't work".
- Can it turn WIFI on ?
- Can it discover network?
- Can it connect to the network?
Which part is the problem.
Cheers

1. Couple of elenix , fusion rom , and others,cant remember their names.
2.Yes WiFi turns on ,discovers my network,says that it remembered it,but at the last step it says on the network Disconected,and on Wi-Fi disconected,and wifi begins to connect to it again,and it can happen like that forever.
I would think it's router related.
Have You tried with other wireless networks ?

[Q] Cant find my wifi at home

I cant find my wifi at home. I see other modems in my area. I flashed my x10a to 2.1-update1 generic with fashtools (didnt root it) and then plugged it in to SEs updater, it updated and everything works fine other then the wifi problem.
Please comment if you can help or have the same problem.
Yeah, I seem to have the same problem, when I try to connect to a router, it suddently disappeart... And then getting unsuccesfull connections...
Does anyone know why this happens, or happen to know a fix for it?

What kind of security is your wifi modem is having? is it wps smthng lk that? Did you tried with different wifi hotspots?
it doesnt have any security, i disable it
The thing is that it doesn even recognize that there is a wifi signal, it just turn off automatically before without detecting any wifi signal, i tried at work and the same thing happened
(sorry if i misspelled a lot of words jejeje)
try to flash another ROM and see if it works...
Sent from my GT-I9100 using XDA premium app
i restored the backup i made with cwm and everything works fine now (touch x-power rom), and if i reinstall check rom the wifi goes out again, it seems it deletes something that leaves me with no wifi mac adress (i searched in about the phone, turning on and of wifi and every time it said not available)
Bizarre...
im getting the same thing, did anyone find a solution?
had this same exact issue.. it is a hardware problem.. so changing rom, kernel or fw wont help you at all... only solution is going to samsung service center.. my problem was solved in 3 days..so many s2 users have this problem..
take a look at these threads...

There are a lot of problems with KK5 and wifi. If you update Busybox it borks it completely. I can't connect to my 5Ghz home wifi but the 2.4 Ghz works fine. I also can't connect to some wifi that uses WEP. All works fine with previous builds. I have seen threads that suggest replacing the wpa_suplicant file from Android 2.3.5 fixes the problem.

My problem was unable to turn on wifi, wifi stuck at the stage of turning on.... and forever like that cant off and on.
Most probably is hardware problem coz i have tried many ways to solve including flash back to stock rom,change modem,change kernel and etc.
good luck for you,hope you are not the same problem with me.

Wifi is kernel-related.
So, try to flash another kernel to test.
Or if you don't want to flash another kernel, check in menu Settings > wifi > (menu button) Advanced > Use static ip.
Try to enabled and connect.
Then disable and try to connect.
If that does not help, try to wipe cache (and Dalvik cache) in recovery mode.
Press Volume UP + Home + Power buttons as long as the recovery menu appears, then select wipe cache and reboot the phone.
P.S.: Check the configuration of your wifi router / WLAN access point, that is allows your phone to connect.
ok so i did everything again just to be sure and... my mistake! the problem starts not after the rom flashing but after cf root! have i done something wrong maybe?
I would say look for a custom rom that is already pre-rooted so then it should have all bugs to do with wifi removed.
I used to have a problem with the wifi myself which caused problems when turning it into a wireless hot spot and then wouldn't turn back off again.
But now im on the Custom Rom I am having no problems with wifi at all.
Hope this helps.

Actually, I would say try a different kernel. CF-root is a kernel. Wifi drivers are in the kernel. Ergo... ?
Wifi is kernel related issue
try changing your kernel
you mite wanna chk dis

may have something to do with the root. my phone had this issues once. just flash your phone with the correct rom and do NOT root it again as it may have something to do with the root itself. or just something got messed up during the rooting process
