Inspiron 1520 will not connect via wireless

Question

I have a refurbished Inspiron 1520 that I gave to my daughter yesterday for Christmas. It has a 1390 WLAN card, running Vista Home Premium. I cannot get the system to connect to the wireless router. I've configured the connection (to a Linksys router on 802.11g using WPA), and it shows in the connections screen. However, when I attempt to connect it states that the association failed for an unknown reason (really helpful message, that). I reconfigured the router and turned off all the security; still no connection (with the same message). I turned off the Windows firewall; same thing. I checked the TCP/IP properties to insure that DHCP is on - it is. The wireless switch is on, and in the momentary position it will see the network. Just for the heck of it I disabled IPv6; still no luck. I haven't yet installed any anti-virus software, so there is nothing to disable / remove there. I've successfully connected to this same network with PCs running w2k and XP, including my work Dell Latitude, which has the same wireless card.   I'm connected at the moment using a cable to the router. Any assistance will be greatly appreciated!

Do you by any chance have MAC Address Filtering enabled on the router?    Steve

D'ohhh!!!   That did it. I can't believe I forgot about the MAC filtering, but it's been a long time since I added any new devices.   Many thanks!
