I'm using a TL-WN821N TP-Link wifi adapter. I have good internet connection when using Windows, but unfortunately I have a bad internet connection in Ubuntu 18.04 and 20.04. I tried numerous ways to fix it, but no there has been no improvement.

I think I managed to install the driver, I used another thread, but internet speed not increased. Is there something else I can do?
