I had the same problem with my wireless router (D-link). My son spent an hour on the phone with their tech support and couldn't find a resolution to the problem. Needless to say we went out and bought a new router given the frustration we were having with it dropping connection. If you haven't already done so, try a firmware update http://www.tech-faq.com/linksys-firmware.shtml to see if that resolves your problem. If it's beyond the warranty period and the firmware update doesn't resolve your problems, you may need to buy a new router.
