Cannot get a wired network to work with a arris comcast cable modem
Having a issue getting a wired ethernet network working when I recently switched to Comcast from att uverse. I purchased a Arris Surfboard cable modem and create a wireless network using a airport extreme. The wireless network works just fine. I have it set up DHCP and NAT. The issue now is that all my wired connections are unable to connect to the internet anymore. I have to run all my devices in wireless mode now. I was trying to keep as much clutter as I could off of the wifi network to help keep proper download speeds. The connections are as followed: Arris Surfboard ethernet connection -- network switcher. Network switcher -- airport extreme & wired devices (blue ray, apple tv etc etc). Has anyone come across this issue? Do I need to go right from the Surfboard modem directly to the airport extreme; then airport extreme to my network switchers with my ethernet cords?
