Three MiniPort WAN are dysfunctionnals and are displayed with a warning by Windows. In ordre to solve this issue I need to be able to uninstall these drivers. There are some explanations available, but they do not work with Windows 8.

Last week I was called to troubleshoot a Lenovo Thinkpad that could not connect to the network. Device manager showed the Realtek NIC, a Centrino wireless adapter, Teredo Tunneling adapter, and six listings for WAN Miniport adapter, all of these items with the yellow triangle and exclamation point. It was not possible to update the drivers, because no network connections were available.

Even a wired connection would not work. Whenever I tried to run the troubleshooter, I got the error that the Diagnostics Policy Service was not running.

After much googling, I eventually tried uninstalling the network devices and rebooting to have Windows reinstall them. This didn't work, as soon as I tried to use the driver, the yellow triangle came back. Finally I decided to reformat back to factory settings. After reformatting, I was able to add the laptop back on the network, with both wired and wireless connections working. In Device Manager there were listings for Bluetooth adapters, the LAN adapter and wireless adapter, and a single WAN Miniport adapter. I disabled the option to allow these devices to turn off the computer.

I was able to browse the network and get online to update software. After I left to do something else, I came back and the laptop display was off, so I had to hit power to bring it back. I logged in, and the wireless connection had dropped. I was able to reconnect, but that shouldn't have happened - it's unusual behavior. I went to Device Manager and now there are two WAN miniports, and #1 has the yellow triangle and is not working. #2 is working. Again I went to the power options and disabled the option to allow the adapter to turn off the computer.

Now I am wondering what's going on, and if the problem actually is hardware-related and not driver-related. Why was it working OK yesterday and now I'm getting errors again? Is this possibly a hard drive issue? The laptop is less than 2 years old. I'd appreciate any advice.
