Unable to access router through two different wireless cards

[videobruce]

Using two different wireless cards, I can't access the router with either. The current error message is;

Data frame errors, check WEP settings

The only thing is I have security turned off in the router and the card.

Details:
Intersil SL2511CD EXT2 (WEP only)
Linksys WPC54GR (various choices)
Westell 327W DSL modem/router (WEP & WPA-PSK)
XP Pro sp2
HP ZV5000 Laptop using Carbus slot

I assume the registry got corrupted somehow. I orginally have been using the Intersil no name card since it has a external antenna. I then got the Linksys 'G' card. I removed the 1st card and installed the 2nd and tried to use one of the security protocols, but I couldn't get it to work. I turned off encription and it still wouldn't work.

Can I have drivers & software for two different cards installed in the Laptop at the same time?
I did removed the software of both cards and re-installed the Intersil S/W by itself. Where are the registry entries for this?

I have reset the router and now I get a 'not connected' message from the card even though it sees the AP. The router does see and list the card with it's MAC address.

Have you checked the firewall on the PC?

No firewall on either the PC or router.
