Comment 20 for bug 1881214

By installing an OLDER mainline kernel 5.3.18-050318-generic x86_64, the behaviour has reverted to what I had before Ubuntu 20.04, meaning: if the router switches the canal for the 5 Ghz band, connection is lost and then a new connection is set on the 2.4 Ghz band.

Interestingly, what can be seen in attachments in message #4 and #5 is happening too but is not reproduced endlessly, just a few attempts.
