In my experience, when you switch from WiFi adapter to another, you have to get rid of the old driver and any software that came with it. That's not always easy, and I don't claim to have all the answers, but I'd start with Device Manager and uninstall the Linksys driver there, then go to Control Panel and uninstall any other WiFi software, then install the driver for the Netgear adapter.
Good luck.
I am running XP home on a older Sony Vaio laptop. I've used a Linksys wireless card to access the internet, but after years of sticking out the side of the computer, it broke, and I replaced it with a Netgear WG511v2 unit. The computer will not recognize the card in either slot, so of course it's not showing up on the system tray. I haven't uninstalled the Linkysys software, thinking I may have to use my USB device in worst case. The Netgear software setup went fine until I was told to insert the card, then nothing proceeded after that. Device Driver says the slots are working as they should, so what could the problem be? Is there a driver that I can update? Microsoft Update says that everything is current when I check that. I've tried everything I know to try, and am getting frustrated with my lack of success. Any suggestions?
