Have you tried just power-cycling the router? Sometimes that helps for connecting new devices to it.

Have you tried changing the authentication type? I found this was an issue on a couple of older wireless routers I own.

Upgrading to 10.04 destroyed my wireless connection too. It seems to be a common problem.

My wireless card was not even detected by 10.04.

I "fixed" it by reinstalling 9.10.
