can you setup static with DG, DNS? If yes, does that work?

 I friend of mine is having a problem connecting to a wireless network.
 He has a laptop and a desktop which he uses with the same Linksys USB
 802.11g wi-fi adapter.
 The router is also a Linksys - acting as a DHCP server.
 The laptop (Win XP SP2) connects fine.
 The desktop (Win XP SP1) with the same USB device, will find the network,
 obtain an IP address but not successfully resolve the Gateway address - as a
 result of which it does not network properly.

 Amazingly enough, IPCONFIG /ALL shows that the correct IP address (same as
 the Gateway) is shown for both DHCP and DNS servers, but it just won't
 resolve the Gateway address, which is just left blank.

 We have checked that there is no vestigial static Gateway address in his
 TCP/IP settings - but I don't know what else to try....

 Any ideas?
