iPhone 3Gs 3.1.2 no wifi after reboot from blakra1n

It had worked perfectly until my iPhone suddenly switched off, and I've always been in this inifinite recovery loop.
I rebooted it with blackra1n, and voila, back to square one, I could not find my home wifi signal and I presume, ANY wifi hotspot.

How the hell do I fix this problem now? It did have this problem, I got it fixed, but I just can't be bothered to go back the shop, so, how do I fix this myself?

No wifi can have at least three causes:

hardware, blacksn0w/apple bug, other/unknown

A syslog from your iPhone can indicate which category you have.

disable 3g!!!! ( Unless you also use 3g, then you disable wifi right? cuz there would be no need for 2 internet source connections... )

Sounds like the race condition caused by blacksn0w unlock.
There is no fix for this.
What you can do is if you installed blacksn0w via Cydia, then go to Cydia to uninstall blacksn0w. After uninstall, you should get wifi back.

Now if you need unlock, you can reinstall blacksn0w and hopefully it won't interfere with wifi again. This is just a hit/miss process. No real fix/cure for it.
