|Well folks, if it's not a driver issue, and the device isn't disabled, about the only thing I can think of trying that might fix it is to go into Device Manager and uninstall the device. Then, reboot and let windows "find" the device again and reinstall the drivers.|
I've run into a similar issue before and if none of the above works, we're generally talking about a hardware failure (ie: the network interface is toast) and usually means replacing the device.
However, with some of the Dell laptops at work, in a similar situation, a complete reinstall of the operating system from scratch has fixed the issue. So before replacing the device, you can try that......although it is drastic and does require you backing up the stuff you don't want to lose before starting.
One last thing, if your laptop is under warranty still, take it in and have it looked at before you reinstall or get a new NIC.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
