ok listen , there will be a cat5 cable comming out of the back of your computer, this is going to the last router if I remember from last week, either way, leave this plugged into the back of the computer, follow it until it connects to whatever it connects to, then disconnect it from whatever it is connected to, leaving it plugged into the back of your machine, plug the other end into the voip router, and click the link that says 192.168.15.1 , and you'll be in the voip router.
