Any update on this? 

I have newly bought AC1300 v2 and it's driver is not working properly. 
Device manager is detecting it as Unknown Device > Network Controller. Any methods on how to fix this? Already tried downloading the latest driver and still a no go.

@Kevin_Z 

Installing the latest driver for T6E doesn't do anything.

As you can see from the image below, after installing the driver downloaded from the tp-link website:  Link
it doesn't add a new adapter for network. i guess the driver is wrong.

It seems I don't know how to install the link you have provided me. Can you do me a detailed instruction for this? Thanks a lot! 

Also while following your instructions: I encounter this while following what you said earlier.

@StephenC123 I found an easy fix.

If your adapter is identified as an unknown network adapter in your device manager, right-click on the device, and select update drivers, go for the option that lets you select the files from your computer. Then download the drivers for your version of windows over here https://www.tp-link.com/en/support/download/archer-t6e/#Driver

Select the folder located in "plugins" called "Driver Files", click install, and that's it, it should install the drivers. If you selected the correct drivers your device should be working now.
