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.
