I am assuming that you have enabled the wireless networking in the wireless network setup menu, and then pushed on the connect to wireless network. If your router is not set to broadcast your SSID, then you need to refer to the Advanced Network Settings. If the router is too far away, that can affect the signal, or any obstructions in the path of the signal. You could try a signal repeater in the path from the router to the Acculink Unit. They make some that just have to be plugged in to an electrical outlet, like plugging in a lamp, etc.
