In the past few days, I have observed that:
- if my wireless connection is set on the 5 GHz band
- when the router switches the channel
- a notification that the connection is lost is displayed
- within seconds, a new connection is made on the 2.4 GHz band (I have a
connection profile with lower
Maybe I was too happy too soon. Today, using iwd, when the channel on
the 5 GHz network switched, the connection was lost but there was no
notification and it was impossible to connect to another ssid. The log
files didn't grow endlessly though.

The behaviour on channel switch on the 5 GHz band seems somehow erratic as what
happens can be either:
1 - what I described in post #23
2 - syslog and kern.log grow endlessly, as seen before
3 - the wifi card disconnects and manages to reconnect itself as seen in
included log file "syslog
With the recent updates, including:
kernel 5.4.0-40-generic x86_64 and (I suspect) wpasupplicant 2:2.9-1ubuntu4.1

endlessly but there is still no attempt to reconnect to another SSID nor

Title:
Intel Wireless 8260 [8086:24f3] Subsystem
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

Had the same issue again today when the router changed the channel from
52 to 36. Same log files.
I guess a workaround is to stick to the 2.4 Ghz band with which I have
not experienced channel switch.

I think I can tell more about the circumstances:
1* My computer is connected by Wifi to the modem / router on the 5 GHz band,
(let's say) canal 100.
2* After a certain amount of time, the router switches *itself* the canal to 36
or 52.
This amount of time is vary variable and independent of
Unlike what I thought or hoped, using an upstream kernel (5.4.43-050443-generic
x86_64) is not a workaround.
I just had the same issue again.
