Re: NUBE - need more ethernet ports att Uverse 2WIRE
A switch is the preferred way; just plug it into any of the LAN ports on the AT&T router.
If you already have it you can probably use that Netgear router. First, hook it up to a computer (do NOT connect it to the AT&T router yet) and log in to its admin interface and disable the DHCP server. If it does not allow you to disable the DHCP server then it CANNOT be used. After you disable it, just use a cable and connect one of its LAN ports to one of the LAN ports on the AT&T router. Do not use the WAN port for anything.
