|While trying to find a fix for the problem that no network connection was shown in the "Network Connections" section of the control panel I tried to uninstall my LAN adapter from the Device Manager and restart the system.|
The device was detected, and I chose the correct drivers from the CD (and again more up-to-date drivers I had on my HD). Then I got the message "the hardware you installed will not work until you restart your computer.
After restarting the system the device appeared again the the Hardware manager, but with an exclamation mark on it, and in its properties the text said "This device is not working properly because Windows cannot load the drivers required for this device (Code 31)".
I downloaded (using a different computer, of course) an installation utility from Intel's website, and this application gave the message that no device of the kind for which I was trying to install the drivers was present.
I tried to connect a USB wifi device, got the drivers for it, and got the same results: the device is shown in the Device Manager with an exclamation mark on it, and with a message that Windows cannot load the driver for it.
So it seems that the problem is not with any specific drivers, but with network adapters in general.
How can this be fixed?
