WiFi will not switch on - Galaxy S II Q&A, Help & Troubleshooting

I had been running the official Samsung version of ICS on my phone for a few months with no problems (updated via Kies).
Last weekend I rooted my phone but afterwards WiFi stopped functioning. When I tap the icon in the pull down menu it goes green, and then greys over. In settings it says Wifi is turning on, but it never does.
I tried flashing a new custom ROM, new Kernel, reverting to stock ICS from Samsung, unrooting. All with no success. Same issue.
Finally I flashed back to gingerbread in the hope that it was an ICS issue. That didn't work either!
I've searched and searched but found very little info. For the record, yes I've factory reset and wiped cache etc etc.
I'm open to any suggestions at this stage. Thanks.

Try a different baseband/modem.

Thanks I'll give it a try. Is that not more to do with the mobile network though than with wifi?

I think changing baseband will not do anything.wifi is controlled via kernal i guess.

I had that probem after I upgraded to resurrection 2.6 from 2.5.1. The problem persisted even after I restored the 2.5.1. (The camera also stopped working) I solved the problem with flashing the phone with the stock ROM. I am also interested to know why it happened? (Problem with 2.6 resurrection?)

Very interesting actually. Thinking about it I flashed to Resurrection Remix 2.5.3 almost immediately after rooting, and I think this is when my problems started. Only thing is that I've since flashed backwards and forwards through various ROMs, Kernals and versions of Android to no avail. Have you a link to the stock ROM you used?

I had this problem when I first got Resurrection remix 2.5.3, the problem lied in the siyah kernel I was using. I proceeded to wipe my phone (factory,dalvik,etc) and reinstalled the resurrection remix. But this time I went to custom installation and changed the siyah to the newer version or fluxi and wi fi started working again.

Thanks for the reply. I'm running Resurrection Remix version 2.6 at the moment and flashed the Siyah 3.4.1. Still the same problem.
Almost certainly the problem first happened when I installed RR last weekend, but nothing I do seems to solve it!
Any further suggestions?

Strange..

Could someone possibly help with a small problem... I cant seem to get the home button to work anymore instead i have to press to the right similar to how the new Nexus works. I would prefer pressing the button but cant see any settings for it. Hope this description is reasonably clear
Thanks

Did you flash something right before this started happening?
if it was after a flash.... try reinstalling from your back up.... could be a bad flash or an incompatible rom?

That's my guess, and what I'm trying to determine with my above question. If he did flash something, I'm guessing he flashed an I777 ROM to his I9100, or he actually has an I777, and flashed an I9100 ROM.
Right...
Yep, i flashed the Resurrection Remix ics v1.1 PRO[XXLPE] rom but as I was getting a few problems I flashed the Turkbey V5 back. I was getting the same problem with Resurrection Remix as well as some fc ?
Thanks

Usual answer is factory reset, see if that helps. If not, re-flash your ROM. If that doesn't help, re-flash back to stock.
Did you follow the steps for installing RR 1.1 fully, wipe dalvic, apply after boot fixes etc? There is a good walkthrough somewhere on this forum, check it out.
I made a more detailed walkthrough for Remix (in my sig) but v1.2 will be out any moment which will be more "n00b" proof with less steps. I'd wait for it, if you are considering to try it again.
Here it was this one I meant...

[Q] 3g wont switch to HSPA after sleep on ICS

Dear All,
I've went ahead and flashed Sensation Rom a while back with full wipe etc.
Ive noticed that on my network (Cytamobile Cyprus) everytime my phone went to sleep after woken it will never switch from 3g to H, giving horrible speeds as a result -200 300kbps. However if data network was turned off and back on - H would work and i would get full speed. Ive tried a variety of ICS roms (even the official carrier update) and modems, even tried flashing a GB modem that I was using on my GB rom - no results.
Please Help.
Currently had to restore back to GB where my connection works fine.
If anyone has any advice on the matter I would really appreciate. I really like ICS
Best Regards
N!K!
Doesn't anybody have the same problem?
Backup, FULL wipe and give wanamlite ICS ROM a try.
If you still have connectivity issues, then flash various modems from the modem thread to gain best reception/stability/speed etc.

I've had the same issue running Resurection remix 1.8.
Fixed it with a full wipe and RR 1.9.1.

Thank you all. RR 1.9.1 fixed my problem. On the other hand too many SODs guess will have to reflash something else.

Sleep of Death....what can i do?

Hi,
For the past while i was getting the SOD only using Siyah based kernels and Phenomenal was working fine for me, but after updating to version 6.1 my phone has started to switch off again. Is this a problem with hardware and do i need to send the phone away for repair or can it be fixed by myself some other way?
I have went back to Phenomenal 5,5 kernel and am waiting to see if i still get the problem.
Cheers.

Hello,
I have tried just about all the latest ICS and JB roms......
The make of your phone. There are many different variants of your device. I9100 G/M/P/T
Are you rooted/unrooted?
What rom you are using? -and- What kernel are you using?
Have you flashed any mods/scripts/themes?
Have you changed DPI? If yes, to what?
I have a UK T-Mobile Samsung Galaxy S II I9100XXLQ6
I am rooted
I was Dual Booting with SuperNexus JB Build 2 and Portal Rom 2.4 using the latest siyah kernel and i got the SOD using SuperNexus, i then removed The second rom and used the ultimate kernel cleaning script to remove Siyah and installed Phenomenal 6.1 with Portal Rom and i got the SOD a day later.
I am not using any mods or extra scripts
I have not changed the dpi
I noticed this problem when i first tried a dual boot a few months ago but has been stable until now only with Phenomenal 5.5. i have tried the other siyah based kernels and i still got the SOD.
Yesterday i flashed the Phenomenal 5.5 along with Portal rom and it's been fine so far but i can get 2-4 days before it happens then it happens a few times daily after the first SOD.
EDIT: Thats it switched off again. Think i will need to send it in for repair?

[Q] Network Problem with Paranoid Android 2.5. Please help..

Hi all,
I installed PA v2.5. Everything worked well except my phone network signal. It is not detecting any signal. Did every thing i could do. wiped system/factory reset, wiped cache partition and dalvik cache. Fixed permissions. Formatted system. tried installing rom a number of times. Changed kernels from stock kernel to siyah 4.1.3 and 5.0. But none of the method worked. Please suggest the way i can get my phone signals as without network signal, it doesn't remain a phone.
Have you tried flashing another modem? You can download a modem here.
Why don't you try to install an other kernel? Different from siyah and stock... As kernels define how hardware work...

You installed siyah 4.1.3 with PA 2.5? They're not compatible and the phone shouldn't even have booted.
Anyways, if you're not able to get a signal, your modem has probably changed. You can check if the modem currently on your phone (settings>about phone) is the same as the one you originally had. ( I assume you've noted down your original modem details somewhere. And flash that modem from the link mentioned above. It should work

so please suggest some other kernel that works fine with pa2.5. I had installed i9100DDLPA base version originally. and now i have flashed it. still not getting signal. sometimes it appears but disappear next moment. it happens frequently. Now i have switched to stock ics 4.0.3. but i want this rom. i flashed resurrection remix and found same problem. but flashing stock modem fixed it. But its not working with pa.
Use siyah 5.0 or dorimanx 7.4 (or higher if there's a later release.) I think the siyah dev gokhanmoral has blocked siyah 5.0 downloads for some reason, so use dorimanx 7.x for now.
Flash the PA ROM, it'll automatically install the default kernel its using. You can install dorimanx after that. And then if necessary, the modem that works for you. Also you can use the getRIL app to match your radio and baseband. May help.

Hi, i love PA too but we have the same issue. Not exactly the same though. I get signal when i boot my phone, i get an H signal (the highest i could get before the issue) but after flashing PA, it drops to E only after about 2minutes. Pls pls reply back if you found a solution. I have tried different modems and kernels already, verified that Siyah 5 is not compatible, tried DorimanX, same thing. Tried 2 different version of PA, no luck. Not to mention that i also tried another sim.
GetRil did it..
Hurraaayyy....
getRil app solved the problem.:laugh: It gave me the option of flashing modems which were matching my phones modem hardware. Thanks to all guys who helped me. Thanks a lot. Anyone having the same problem as of mine or any network related problem please give a try to getRIL app. May be it could work for you too.

[Q] Wi-fi Toggle Switch is disabled :(

Hello Team,
I have been a silent follower of this website and have rooted my SGSII 6 months ago. Everything was working absolutely fine with no problems.
Very recently I upgraded my build to 4.2.2 JDQ39 with Kernel Version: 3.0.64-CM. My wireless is not working at all. I am not even able to turn on the wifi option.
I tried installing the below ROMs to check the functionality:
ThinkingBridge
Paranoid
Resurrection.
None of the above worked.
I'd request anyone in this thread to give me a workaround or a solution to fix this thing.
Thank you
Harry

Anyone in this forum has experienced this issue before me? Please advice.
Do a clean (format everything in CWM first, then use Odin) install of stock & see if the problem persists. Tho you've tried these other roms, you might have left something funky behind from one of them (just doing a wipe may not get rid of this) that has persisted.
If you have no problems with stock, try another install of the custom rom of your choice & see how you go.
Or maybe even try a completely different kernel before you do the stock thing. Try Siyah/Dorimanx maybe ?
