Try removing WEP\WPA\MAC filtering..can the clients connect? Enable ESSID (network name) broadcast…do the Windows XP clients “see” or discover the WLAN?

There are still a ton of additional steps however this is a good start.

It's one of the first items I check when either installing a new router for one of my client or working on one they've already installed themselves.

Many times people place their computer and networking equipment into small physical spaces and it causes problems with items, especially those with reflective surfaces (CD's metal object, etc..) , come between the router and wireless adapter.</p> Checking the firmware version of the router.
