iphone 3gs wifi issues after upgrading to iOS 5 and jailbreak

[paaji]

Hi,
I installed new ios5 on 3GS and jailbreak it. I have to reboot the iPhone to get the wifi working again as keeps on disconnecting. It remains on for few minutes then WiFi icon disappears.
When you manually go to Setting > WiFi look for SSID (It keeps on looking.)

Before the upgrade it was working fine.
Any suggestions
Thanks

I'm assuming u meant 5.0.1....try removing any JB apps u added and see if that helps...if not try fresh DFU restore and try again before u JB...

What baseband u have...

After jailbreaking it I just restored the apps on it. Not sure if that caused it. I will try to remove it and see if that helps.
Baseband is 5.13.04. I installed Ultrasn0w for unlock.
Thanks
