Comment 3 for bug 1867559

I have Acer Aspire A315-42G with the same WiFi adapter and suffer from the same bug. On Windows 10 I get 200Mb/s download speed (limited by Internet provider, sorry, don't have anything else to test on LAN), on Ubuntu 20.04 at the same spot I get 30Mb/s download speed. My region settings:
