No wifi after jailbreak

[cj311redd]

My jailbroken 3G (4.2.1, 6.15.00) shows that it is connected to my wifi but I can't load any sites and I can't get on Cydia to unlock the carrier. I've tried to reset my network settings and that doesn't help. Also, I entered my wifi password wrong once and it showed that I was connected and receiving a strong signal. Thanks

Can you browse the web on the same wifi from another source ?

Try re jailbreaking using sn0wbreeze with a custom firmware and try again

Yes, from another jailbroken iPhone and my desktop.

Ya now that your on 6.15.00 I would reload with a custom Ipsw but when I do it I always get errors unless I use redsnow and use the boot dfu mode first then use iTunes shift restore

Just tried the dfu mode and iTunes shift restore with custom Ipsw, still having same issues with wifi
