I have Charter Cable internet and a SMCD3GN2-RES Gateway and I was wondering if it can support multiple Xboxes. Right now I have it setup with a few switches in the network but I can't seem to get both of the Xboxes on open NAT at the same time. Also, my PC loses connection randomly and can't game online.

Should I just buy a new Modem and buy a router? Or buy a gateway instead, or will this work and i'm just retarded.
