Problems with XBL/switchbox and network

Hey all! I am having an issue with my Xbox an my internet connection. I have an ATT UVerse 2 Wire router/modem that I am using. I have that in a closet an that connects to a wall ethernet port. From there that connects to a Netgear GS108 Gigabit switchbox. From their I have main line in port 1 my xbox in port 2 my PC in port 3 an ps3, cablebox and another item as well.

The issue I am having is that I will boot up the xbox an it will stay connected maybe 5-8 minutes on the dash an then will boot me off xbl. This is especially annoying using netflix which boots off then I have to reconnect an such all over again.

I did port forwarding an also changed from a Auto connection to a manual one. This resulted int he same thing over an over again. I am at a loss as to what to do an was hoping someone might have an answer for me.

Try swapping ethernet cables, could just have a bad cable, if you did not run cat-5e or cat-6 to each location. If you ran ethernet, re-terminate the rj-45 keystones.
