I have 2 iPhone 3gs and an iTouch. 3g's are on FW 3.0 and the iTouch is FW 2.2.1. All three devices locate and log into my wifi fine and have good signal. BUT none of them will go on the internet. They cannot connect for mail, weather, safari or any app that uses the internet. My laptop connects just fine (I'm using it now on the same system to write this). What could possible be preventing any Apple device from jumping on the net????? I haven't seen this ever happen before. Please help me!
