I forgot to mention that this is all under Service Pack 3, which seems to be breaking lots of people's wireless connections when they are using WEP or WPA encryption. Changing to WPA-2 isn't an option for me, so I'm uninstalling SP3 to see if that makes a difference.
I need to find a driver compatible with SP3 that will work with my Dynex card. Is anyone familiar with this? I forget, but doesn't Dynex use Broadcom drivers anyways? I'll look into this further.
Update: Rolling back to SP2 didn't change anything, not even after I installed the original update that allowed XP SP2 to use WPA2. I've now tried all kinds of security, save WEP, and none of them work. Looking more closely at my router's logs, it's telling me that half the time my computer fails to authenticate and the other half, it starts the authentication process but my computer never responds. The connection won't even work when the network's security is completely disabled.
