All of my mobile devices won't connect to WiFi
I've tried so many things to get my devices to connect, I know this is the Android forum but it's my tablet and my iPhone won't connect, yet my Desktop with a WiFi card, laptop, and my game consoles work just fine. On my Android tablet, it loops on Obtaining IP Address and I tried WiFi Fixer but no avail, and my iPhone just won't connect, it doesn't say "Can't connect to" it just shows the spinning circle and my iPhone stays on 3G.
I have a netgear router if that helps, in VERY rare cases, one of them connects but then they get disconnected after a few minutes.
It doesn't work even if I set a static IP either.
EDIT: This is a Android forum, my tablet is a DOPO T708. It's not listed here in the forums, so that's why I posted in General.
