A linksys router connects to the cable modem and does all the DHCP in the network. A Netgear router is then connected, but set not to assign DHCP (so it's basically acting as a dumb switch). This configuration gives me internet, but I'm having a problem setting up a LAN game on two computers connected to the Netgear. Whether wireless or wired to the Netgear, the laptop can not ping the desktop (also wired to the Netgear), but the desktop can ping the laptop. Why am I not getting pings both ways?
