Enable 5Ghz networks with TP-Link Archer T2UH on Windows 10

Recently I was faced with a serious problem after upgrading to Windows 10: My Archer T2UH network stick suddenly refused to scan for 5Ghz networks. Living in an apartment complex with more than 15 other 2.4Ghz networks around me, I am forced to use 5Ghz for network intensive tasks and gaming.

But I didn't want to rollback to Windows 8.1. So what to do?

TL;DR: Install the old driver "Archer_T2UH_V1_Driver_140821" from the TP-Link support page.

What you have to do:

  1. Go to the driver download page on the TP-Link homepage. Download the "Archer_T2UH_V1_Driver_140821", which was released sometime in 2014. Remember not to download the latest driver.
  2. Uninstall the current driver, which should be the "archer_t2uhv1_150108" or something similar. Go to the Windows device manager, right click on the t2uh network adapter and select "uninstall".
  3. Once you have uninstalled the driver, the green light on your network adapter should not flash anymore.
  4. Install the driver you downloaded.
  5. Your TP-Link Archer T2UH should now be able to scan for 5Ghz networks again.
