See the "Multiple NICs in XP Pro" above. I had the same issue...

The problem is probably that the wired router is acting as a DHCP
server and assigning a default gateway to the desktop's wired
connection. Since the default gateway is used to access the Internet,
the computer must only get a default gateway assignment from the
wireless router.
Connect to the wired router's built-in web server (usually at an
address like http://192.168.0.1 or http://192.168.0.2) and disable the
router's DHCP server. You can then assign static IP addresses to the
wired connections on the desktop and laptop, but don't assign default
gateway addresses.
