Wireless card problem?

[btsdev]

I have a Dlink air plus G510 on my win2K machine. all of sudden it stopped working. I can seem to get the card to connect to my router. I tried the card in a different machine and still NG. I have re-seated the card, re-installed the drivers. I have also tried disabling and re-enabling the network connection. each time it say "connection failed". before I throw it out and get a new card any suggestions? By the way I diabled the MAC filter on the router. any suggestions? Is this common?

Can the card see the network?

Have you tried connecting without any encryption? Changing the channel on the broadcast? What about the D-Link site for updated drivers? Did you make any changes to the computer's hardware/software around the time this happened?

Have you tried rebooting the router? What about a firmware reset?

How many more questions do you think I can ask?
