[Q] Please help.. Wifi issue. - Galaxy S II Q&A, Help & Troubleshooting

Hey guys, posted a thread the other day. But didn't get much of an answer. But now am back with a different question. Anyway, long story short. My girlfriend is a goose and swapped a perfectly good iPhone (wait what, how can an iphone be good - i know, i know) for a samsung galaxy s2. It kept turning off and wifi doesnt work.
I done an update to 4.0.3 using odin and that stopped the constant turning off, but wifi is still not working.
Now what I would like to know it, if i change the modem firmware in it, will it fix it ? Could I just try different firmwares until I works ? Would downgrading to say 2.2 possibly fix the issue ? (It was originally 2.3.5)
Please help, if you need information, just post and ill reply )

the modem or baseband is nowhere related to ur wifi issue ma8 for that u have 2 change the kernel and see u can try SIYAH, Thoravukk or Fluxi kernel and see it might resolve ur wifi issue

Im assuming you've tested the router with other devices to eliminate that? It sounds as though the warranty is already void so it could be a good excuse to root & install cwm5 if you haven't already. Like was already mentioned wifi is kernel related so i would recommend installing a recently released aokp (preferred) based rom with whatever kernel is provided. If you're still having the problem try installing different kernels from there on in. Remember to flash a kernel cleaning script before flashing the new kernel. If the problem persists it could be hardware related. Good luck bud !

Yep, the wifi just doesnt turn on at all. switch to on, and it switches off straight away. Is CWM5 (clock work mode ) If so I have that. Could you please link me to a aokp based rom. I'm sorry for being a hassel, just very new and hoping to get this issue cleared up asap, because it is a great phone. Also confused as to flashing a kernal cleaning script ??

Thanks. Do I have to do anything to my firmware, or just straight up put the kernel on ?

No hassle m8 only problem is im on my touchpad so can't send you links. From xda enter i9100 (device) go android development then look for resurrection remix 2.2 Download file place it in downloads "internal" (easy to find) then boot into clockwork recovery. Firstly make sure you backup current rom! After that's done follow these instructions carefully.
Wipe data/Factory reset
Wipe cache
(from advanced) Wipe dalvik cache/battery stats
(from mounts/storage) format cache/data/system
Go to 'install zip from sd card'
Go to 'choose zip from internal'
Install 'resurrection remix'
Reboot then setup Google accounts etc.... Then reboot again & wait 5 mins.
As for kernel cleaning script try this 1st then see how you go.. I'm off to bed m8 good luck with everything!
