the name is of no consequence. Now, you say you can see the info from your BB in the router menus, like attached devices, right? If that's the situation, we can move on to a test...
After it says you're connected, swap to your browser (BB) and try calling up this website or heck just google will do...
If you see your connection arrows (top right of your screen, BB) flickering like mad, then that's a good sign! That means it's trying to pull the data over the wifi...
The next objective is to try and set up your UWA (VoIP via T-Mob @home)...
First, you should see the wifi icon in the upper portion of your screen (BB), next go to your Manage Connections icon and open it...select WiFi Options > Menu > Wi-Fi Diagnostics > Menu > ping > Change the IP or Name field to Wi-Fi Gateway > Menu > Send Ping....
If it comes back unsuccessful check back here and post your results...
We'll go from there...
Cheers!
