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:
- 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.
- 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".
- Once you have uninstalled the driver, the green light on your network adapter should not flash anymore.
- Install the driver you downloaded.
- Your TP-Link Archer T2UH should now be able to scan for 5Ghz networks again.
