I'm bumping this as I'm in serious need of help.
Thinking my issues were hardware related, I exchanged the NC for a new one. The same thing is happening with my home network, no matter its settings (open, WEP, WPA, G, B, MAC filter on/off). Both the B&N Stock and Android (Nookie Froyo) sides connect to the network just fine -- Settings> Wireless> Wifi shows "Connected to Homenetwork" with an assigned IP. However, while I can web browse in B&N stock, I can't web browse, connect to Market, etc. on the Android side. All I can do is connect to my router setup page in Android.
Could anyone point me to a resource to step me through diagnosing this problem? I'm desperate.
