Title:
Cannot connect via ssh anymore after Wifi dropped once - Lunar
Status in linux-raspi package in Ubuntu:
Invalid
Bug description:
I'm using a Raspberry Pi 4 and updated from kinetic to lunar with "do-
release-upgrade -d". Ubuntu is installed on an SSD which is connected
via USB.
[Expected behavior]
After switching off and on the wifi carrier I can still connect to my Raspi
via ssh.
[Observed behavior]
After switching off and on the wifi carrier I can neither connect nor ping
the Raspi. Neither on wlan0, nor on eth0. It looks like the device is stuck.

[Logs from before the Wifi was turned off]
Checking the timestamps of the logs is showing, that logging stops
when the wifi carrier is switched on again.
