Friends with more knowledge,
I have a RV320 router with dual WAN set up, but since I have an ATT Aircard (motorola Aircard 781S) I hoped to configure the router to use the aircard in the catastrophic event that both our Cable and Uverse ISPs go down.
The router sees the modem but is asking for a PIN number. I have contacted ATT and they gave me two PUK numbers but when I hit SAVE it just kicks me back to the previous level menu and gives the message shown :
USB modem is connected, but it requires correct PIN code to enable the USB service.
any ideas? has anybody configured this sucessfully?
