Sees router with strong signal but won't connect

[ESTAGroup]

I just bought a Linksys G router. My desktop is successfully connected to it directly. I have one laptop that can connect to the router without an problems—I get a strong signal and always connected. I just got a new laptop and it can see the router but just won’t connect to it even though the signal is excellent. I downloaded all the latest drivers for my card and have DHCP enabled.

I am new to wireless but a have a fairly strong background in computers. Any help is appreciated.

It's Windows 98 running in the laptop?

Windows XP Firewall settings?
Any other 3rd party firewalls installed - ZoneAlarm etc

If sunflower oil comes from sunflowers, and vegetable oil comes from vegetables, where does baby oil come from?
