Slow wireless for no apparent reason

I've been using a D-Link DI-624 router for some time now, with an adapter card in my laptop and a wireless pci card in my gaming computer in the other room. Just yesterday my laptop stared continually dropping the connection and picking it back up again, and then on the gaming computer I noticed webpages were loading very slowly and when I logged on to World of Warcraft my latencies were between 1700-2000ms! When I checked out the router in here I noticed the WLAN led blinking on and off steadily, not like the flicker of transmitting. D-link told me to reset it and update the firmware, which I had already done, and none of that did any good anyway. All the ethernet lines work fine. Anyone have any ideas?

Thanks!
 
When you say "All the ethernet lines work fine." does that mean that wired computers are working normally? (If you don't have a wired PC already, try plugging your laptop directly into the router with a standard ethernet cable to see what happens.)

If wired computers are having the same problem, then take the router completely out of the picture and plug one computer directly into the DSL modem to see what happens. If it works normally then the problem is with the router. If you still have the same problem, then the problem is with the DSL modem or the connection to your ISP.

If wired PCs are working normally, then you are likely dealing with either a failing radio in the router, or wireless interference from something in the area. Using NetStumbler, your wireless adapter's connection utility, or the Windows XP wireless connection manager, can you 'see' any other wireless networks in the area? If so, try changing the wireless channel on your router to something that the other router(s) is not using. If there are no other wireless networks in the area, check for other 2.4Ghz wireless interference (particularly anything new since the problem started happening) such as 2.4Ghz cordless phones, high-powered microwaves and other appliances, heavy power lines overhead, cell phone repeater tower, etc.

If you can determine that there really is no measurable wireless interference in the area, then I would have to lean towards the possibility that the router is failing.
