The smartcom firmware has been updated several times for various reasons, one of which including the smart com locking up and only solution until the firmware update, was to power cycle the smart com to regain coms.
You are connecting wirelessly? In the early versions of the smart com the wireless was supposed to be deactivated, cant remember when it was when it was officially turned on.
Have you got any further with connecting?
The manual has the correct info in it, as the firmware on the smartcom has been upgraded its become much easier to get installed, done lots of these, the initial connection was the hardest.
if using wireless, I would opt short term to use ethernet cable, get it up and running and everything updated, and then look again at the wireless once the smart com is updated.
