On Windows, downloading a 500 MB file takes less than a minute, but on Linux it is taking nearly half an hour.

Why is my internet speed so much slower on Linux than on Windows, and what can I do to speed it up?

I'm using a wireless network adapter made by Panda Wireless that's working perfectly fine on Windows, so I suspect it's due to a driver issue or something.

    check which wireless protocol (a, b, g, n, ...) that the connection is making under Windows and Linux. On linux iwconfig would be useful. – danblack Nov 1 '18 at 23:11
  • I posted the output of iwconfig above. It appears to be using the n protocol. – tpsReports Nov 1 '18 at 23:45

The RT5372 driver is slow and there is currently no software fix for this.

The recommended solution seems be that you should use a different WiFi dongle. Unfortunately.
