Im having problems with my wi-fi staying connected. I havent had any problems with wi-fi until today (7months)...When i enter the password to connect sometimes it will connect but will disconnect after 5-10 seconds..reconnects and disconnects again..then none of the connections will show up in range...so i reset my network connections then i proceed to join the network once again, enter the pass and it says can not join network....i have restored and jailbroken again but no change.
4.0.1 Model: MB489LL Base:05.13.04 Jail Break:RedSNow

Thanks.....
