I have spent days searching the internet for a solution. My father's laptop keeps getting this error. I have set Windows as the default network manager, uninstalled the Intel Network Manager from the Dell Drivers & Download page specified for his laptop, reinstalled the driver, flushed the DNS, reset the Winsock, and tried everything else the World Wide Web has been able to help me try. It is telling me the Wireless Radio is turned off. There is no physical switch for the WiFi, and I have searched through the settings, time and time again, but to no avail. This happened the first time, and I switched Windows back to the default network manager and it worked just fine. But the next day it happened again and he hasn't been able to connect to WiFi since then. He is on a Dell Latitude D520 running Windows XP Pro SP3. I am clueless as to what to do next. We have called Microsoft and they were to no help. So, if anyone has a solution, it would be greatly appreciated. He needs this fixed A.S.A.F.P.

Thanks,
