Airport Extreme Router and Modem?
I have been having problems with my internet connection for a long time. So now I am wondering if I have everything hooked up wrong. We have internet services from the local electric company. We use an apple airport extreme on one line and an apple time capsule on the other line by using an ether cable straight into the apple routers. My question is do we need to use a modem from the wall using an ether cable before connecting to the apple routers?
