Model: Archer T3U  
Hardware Version: V1
Firmware Version: 1030.29.618.2019

Hello, I have a problem with my T3U Plus Adapter. Every couple seconds when on the 5 Ghz connection, the connection drops to 0 KB/s and then after 2-3 seconds recovers to normal speed. The thing is, everything works fine on 2.4 Ghz and it doesn't lose the connection. The router I'm using is the Archer C6. All other devices on the network don't have any problems, so has to be the adapter's fault. I have already tried installing different drivers from topics on this forum, but to no avail. Is there any fix for this issue other than buying a new adapter from a different brand?

Hi, is the router also Archer C6? Try to modify the 5G channel and channel width on the router, ensure this adapter can receive a good signal from it.

 

Additionally, you may try to update the driver for this adapter to the latest version, you can try the below public driver from Realtek:

Remove all the other drivers on the computer for this adapter, then install the public driver manually: https://www.tp-link.com/support/setup-video/.
