Wifi problem on stock but not on Miui - Galaxy S III Q&A, Help & Troubleshooting

Hey there,
today a friend of mine flashed the Omega Rom 33.3 and got a wifi issue. The wifi never connects and says "Authentication failed", "wrong password" or it just says connecting and after a while it switches back, but on the MIUI the wifi works great. Also the wifi didn´t work on the stock 4.1.1.
I hope somebody can help us. Thanks in advance

Change the kernel .

Thanks for the answer... My friend will try it and I will report if it worked.
EDIT: He tried a new kernel (SiyahKernel S3 v1.8) , also a new modem and it isn´t working at all. The weird thing is, that he got a full nandroid backup of my phone (Omega Rom 33.3), where everything is working fine, but on his phone the wifi doen´t want to work. The wifi worked at 4.0.4, before official 4.1.1 Kies update, and on the MIUI rom.

[Q] i9100 Lite'ning rom issue

Hey everyone,
I am new to these forums. I have an issue and I have searched everywhere for the solution.
I have a SGS2 and I rooted it with Lite'ning Rom v4.2.
I followed the instruction on this thread and my phone loaded the ROM successfully.
I have an issue, since I installed this rom my WiFi is not working.
Everytime I got to wifi settings, I see the available networks, however when trying to connect it just attempts to connect then disconnects.
I saw on this thread that another user had to flash the kernel to get his WiFi working.
I download the XXKG3 kernel for my S2 and flashed however still not working.
I am asking for some help with this as where I live I have no 3G reception so have to use Wifi in order to use internet on my S2.
Any help is greatly appreciated.

No 3G after custom kernel install, all else good, need help...

I successfully installed Humberos JP2, everything I need works fine and it is rooted, but I cant get 3G connection, my Galaxy Tab is the P1000L from Telcel.
The phone is working fine, WiFi fine, but no 3G, could someone give me some help on this?
You could try asking the kernel's developer to help you troubleshoot your problems.
Thanks for your suggestion.
I ended up installing Cyanogen Mod CM9, latest ICS with Humberos Kernel for P1000L,rooted, everything is working as it should, I am happy with my SGT again

Hope you guys got a clue, because apart from that I love the ROM
