Can't browse the Internet to remote web sites (i.e. www.digi.com) via the WAN (cellular) side of the Connect WAN.

Verify that the WAN side is up on the Connect WAN by checking that the Cellular Link led is on and that you have two or more Signal Strength leds on. 

Verify that you have entered the Connect WAN' s IP address (Ethernet) as your default gateway on your work station's IP config along with the correct DNS server IP address from your wireless provider. 

If you have the Digi setup as a DHCP server then the gateway and DNS address with automatically be given.
