ICS Problem

I access the internet through a primary desktop PC with a wireless USB
device (Netgear Wireless USB Adapter). No porblem there. I am trying to
gain access to the web with a second desktop PC which is wired by a crossover
LAN cable to an internel NIC card in the primary PC. Both PCs communicate
with no problem with each other. I can successfully set up ICS on both PCs
which are running XP. No problem still. Everything seems perfect until I
enable the crossover link between the two PCs. At that point they can both
communicate with each other but the internet link to either PC dies. I can't
figure out why. As soon as I disable the crossover connection the internet
link is restored. The primary PC is sharing it's wireless connection as the
internet access point and connects to a router. I have tried turning off the
routers DHCP server function to no avail. What am I missing?
 
Is possible that you setup two default gateways on multihomed computer? Posting the result of ipconfig /all may help.

I suspect that the wireless connection has an IP address in the same
192.168.0.x subnet that ICS uses, causing a conflict when both
connections are enabled. If so, the solution is to configure your
wireless router to use a different subnet, such as 192.168.1.x.
