Hi,

How did you uninstall the drivers? Via the Apps and Features menu or via the Device Manager?

If you haven't done so already open the Device Manager and uninstall the TP-Link adapter from there. Also make sure you tick the box for "Delete the driver software ...". Then click the "Scan for hardware changes" button and the TP-Link adapter should reappear. Do that again until you have reverted to the driver version that shows "Microsoft" as the Driver Provider.

You might also want to select "Show hidden devices" from the menu and see if remnants of a second wireless adapter show up (icons in light blue color). If so, then delete that as well.

Then restart Windows and check if anything changed. If the T2U still won't connect, then I don't know how to solve this either.

  @woozle Thanks for the reply! Sadly I had alerady tried doing this and i've frankly just given up already and am goint to just gonna get a refund. I'm assuming that i've just messed up my windows install somehow to the point where the device drivers are absolutely borked haha

  @Kentobuh  How do I update the drivers in my  Laptop? 
I have go the CD with the product, but I am not able to run it because I have a laptop. On searching the internet, I have got the installation guide in the website. 

The driver is now not able to detect both the internet and the bluetooth. 

  @Kentobuh I have been trying to run this the whole day, it used to work fine after plug and play , why the hell is it not running now??????????????? What am  paying the hell for huh? It comes with a 3 year warranty and it's not running for 3 months. hell chinese

  @Kentobuh Facing the same problem unable to see any networks. downloaded the drivers from the git and installed them. I am using ubuntu but I can see people with windows are facing the same issue. is the device faulty?

  @RoopKumar I found this thread because I was having issues on Windows, but I have used the adapter roughly 4 times across multiple linux distros (except for Ubuntu, but including Debian and openSuSE). Have you tried the 8821au drivers on github? I couldn't get the adapter to work with many drivers until trying that one.
