Connecting to a Wireless Network
If your connection with SerberNet was connected directly to your
computer, then there is a great probability that NAT translation is
active on your radio. After you have your router connected to the
internet cable and to your computer, please contact us to disable NAT
translation and register your router. This picture may help if you are
confused about the cabling:

SerberNet does not use a modem. The flat black ethernet cable will plug into the WAN port of the router.
