If you use your original Win XP disks, there's a chance you now have XP SP1 (Service Pack 1). Make sure you've made all the necessary Windows Updates as working with WiFi networks was enhanced with XP SP2. Then you can try to find your wireless network and connect to it. If you had a secured network you'll need your previous network key (similar to a password, but without a username, the wireless key is needed to exchange data with the router) If you can't remember the settings on your Linksys you can reset it to factory settings with inserting something into the reset hole to press the hidden buton and holding it for several seconds until lights on the front flash. Then you HAVE to run the initial install procedure (find your CD and Quick Start sheet) because your router will be open and unsecured.

Is the wireless card driver installed and working?
Can the wireless card detect your Netgear Router and does it have a strong signal strength?
The Wireless card needs to be configured with the Netgear Router's SSID and encryption settings before it will communicate with the Netgear Router.
Let me know if you have further problems together with error messages.

If the wifi light is off its a sign that there's something wrong with it, so the first thing you can do here is to reset the router, To reset it press and hold the reset button of the router for 30 seconds and then power off the router for 10 seconds....

the drivers should be installed in windows 7 by default, their so called "smart wizard" has some compatibility issues with windows 7, I get it to load up and it will shut down or glitch out. What I did was uninstall the downloaded driver and use the default windows drivers, flipped the switch off to my built in G wifi adapter and the netgear automatically kicked in and took over as the default wireless adapter.
