How can I get my computer on wireless, since it seems that I may have deleted a driver or changed setting somehow. When I go into "Networks Connections" and ask to view available wireless networks, it tells me that "windows cannot configure a wireless connection". My laptop is a Dell E6410 and I am running with "Microsoft Windows XP. Any assistance would be appreciated. Thank you. Angie
If I remember correctly, you have to enable the wireless device before you can configure it. If it's already enabled and you're still receiving that error message, I'd try to re-install the driver for your device.
Go Here and change your OS to MS Windows XP.
Expand the Network tree, download and install the Dell W-ifi Driver.
