Title:
Wireless card with Intel AX200 chipset downloading very slow on Ubuntu

Bug description:
Hi,
I've recently bought a wi-fi card based on Intel AX200 chipset and it is
extremly slow if compared with same network performances on the same ssid (and
at the same distance from router) on other devices.
These are the details of my network

Description: Ubuntu 20.10
Release: 20.10
Codename: groovy
Linux mirko-P5QL-PRO 5.8.0-31-generic #33-Ubuntu SMP Mon Nov 23 18:44:54 UTC
2020 x86_64 x86_64 x86_64 GNU/Linux
I've tried many of the solutions found on the internet:
- setting the option 11n_disable=1 (slightly improved but still slow)
- setting the option 11n_disable=8
- edit /etc/nsswitch.conf commenting the line "hosts: files
mdns4_minimal [NOTFOUND=return] dns mdns4" and adding the line "hosts:
files dns"
- disabling IPv6 support
But results are still the same and connection keeps being slow (no
more than 15 MB/s vs. 300+ MB/s on my smartphones using the same
network).
I hope you can help.
Thanks.
Mirko
