Thanx for the addendum, Britty. I shoulda mentioned NSP and SP1.
Unless I'm mistaken, the default settings for the driver include WEP encryption off and obtaining the IP address via DHCP, so once the driver is installed, it should be plug-and-play assuming that your router is DHCP enabled. So once the driver is installed, just plug in the card and wait for the light.
(It could take as long as a couple of minutes the first time, so be patient.
) If it doesn't connect, then you have to enter the IP address manually. Your router's user guide
(or your Internet service provider if it supplied the router to you when you signed up for Internet service
) can explain what IP address entries you should make.
(These entries are made on your 620LX in Start -> Settings -> Network.
)
It seems a little complicated at first, but after that it gets much easier.
