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
sudo lshw -C network; lsb_release -a; uname -a

Distributor ID: Ubuntu
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
