My AT&T internet is working fine. In fact, that's how I am posting this right now. The Hopper detects the wireless network with a pretty good signal on the Wi-Fi Setup Wizard, but after entering the password, I receive an indication of Router Not Detected. I guarantee I'm entering the wifi password correctly, as I've done it multiple times. The Hopper and Joey are communicating without issue. I tried the main router and the dlink extender that Dish installed for free. No connection either way. Ideas?
