iPad won't connect to wifi anymore
I have an iPad air and the WIFI can't connect all of a sudden. Today I was using it at my hotel and WIFI was working ok. I took the plane home and used Airplane Mode on and WiFi on (streaming movies) and it worked fine. When I got home, it tried connecting to my Airport Time Capsule but the wheel kept spinning without ever connecting. That router is in bridge mode with another router. The iPad can't connect to that router either. My other devices (iPhones, other iPads, MacBook) all connect fine.
I tried resetting network settings.. all settings... restarting the iPad.. restarting the router... no luck. When I open the AirPort Utility from my Macbook, I can see that my iPad's hardware address connected as a client... but it never gets an IP address assigned. All other devices get an IP address.
Any ideas?
