Can't connect 2 computers to the internet on ADSL provided by SBC/AT&T?

Not sure haw many ports on the back of the router, but make sure you are plugged into #1 and #2 port on the router, router and modem connected by cable going to WAN port. Then turn them all off and turn them back on in the order of modem first, let it initialize, then router, give it a minute to set up, then turn on the computers, and they should work just fine. You don't need the Netgear switch. e-mail me and I can help you if you still need it
