Problem: My airport utility and (apple tv) remote app are no longer working Background: Recently moved; changed wpa2 security password for guest network yesterday when DirecTV was configuring whole home DVR using the Airport Utility App. Today, iPad has connected to the internet all-day. Fast-forward to tonight, I was trying to join my 360 to the guest network, which led me down the path of unplugging router and modem. Now, the iPad still connects to the internet, but my remote app no longer works and the airport utility app will not locate my airport extreme. Available Equipment: iPad, Airport Extreme, Cisco DPQ2160 Modem, Dell Inspiron with broken wireless card. Any help would be greatly appreciated. I'm so confused, right now.
