Hello, Since I've installed the package linux-image-amd64 (5.16.12-1~bpo11+1) from bullseye-backports, the speed of the wireless connection is very unstable.
Ping varies constantly from 5 to 1500 ms while it is stable and around 5 ms for the other wireless devices running with bullseye 5.10 and different network devices. Any suggestions to improve the connection would be appreciated. Thanks, lsb_release -a No LSB modules are available.
