how are you attempting to connect the Wii to the router? wired or wireless?Originally Posted by johncf
has DHCP on the router been disabled for some reason?
try allocating the Wii with a "manually assigned" IP address within the same
range as the IP of your pc. e.g. pc = 192.168.1.2 Wii 192.168.1.3
the subnet mask value will be 255.255.255.0 for this range of IP's
the default router (gateway) address will be the IP address of the router.
