I JB my ipod touch 2g from firmware 2.2.1 to 3.0 using redsn0w 7.2 and now whenever i connect to my wifi, i get a very week signal. I only get 2-3bars. Im only like 5 feet away from the router. Anybody know why or have any suggestions on how to fix this? My wifi was great with JB 2.2.1 and now it sucks. Please help.
