I'm having this weird problem. Basically, when my Macbook is connected to my wifi nothing else can connect. Not my iPhone or another laptop I have. I have an Airport Extreme and I have an IPTV connected to it through an ethernet cable. I've tried resetting the router, updated my MBP (10.8.2), iOS6, etc... When my MBP is not connected to the wifi, everything works perfectly. I can connect my iphone and my samsung series 9 laptop. It's so frustrating because I barely have any signal in my apartment, so I NEED wifi on my phone. Anyone have any ideas?
