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 priority) I have: - NO MORE freeze because the log files are taking all the disk space - NO MORE freeze with no possibility to disconnect Network Manager Actually this behaviour on channel switch has been consistent during the last few days and is now what I had with Ubuntu 19.10 and older releases. I don't know what updates made things change but the current situation is fine for me.

[Kernel-packages] [Bug 1881214] Re: syslog and kern.log grow endlessly - related to Intel wifi?
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 what I'm doing on my computer, hence the difficulty to describe the circumstances. 3* There is no indication that the connection is lost. There is no attempt to connect on the 2.4 GHz band, even though I have a connection profile. Then, syslog and kern.log start to grow endlessly, see bug description. With previous versions of Ubuntu: 1* and 2* Same. 3* The connection is lost but very shortly after that the Wifi card connects on the 2.4 GHz band. ** Description changed: Ubuntu Mate 20.04, with all supplied kernels up to 5.4.0.33 I occasionally see a message on my screen that disk space is low.

With the recent updates, including: kernel 5.4.0-40-generic x86_64 and (I suspect) wpasupplicant 2:2.9-1ubuntu4.1 The behaviour has changed: on channel switch the log files no longer grow endlessly but there is still no attempt to reconnect to another SSID nor notification that the connection is lost.

[Kernel-packages] [Bug 1881214] Re: Intel Wireless 8260 [8086:24f3] Subsystem [8086:1010] on channel switch, iwlwifi Microcode SW Error: FW error in SYNC CMD CHANNEL_SWITCH_TIME_EVENT_CMD
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. ** Attachment added: "syslog (older kernel)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881214/+attachment/5382011/+files/syslog%20%28older%20kernel%29 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1881214 Title: Intel Wireless 8260 [8086:24f3] Subsystem [8086:1010] on channel switch, iwlwifi Microcode SW Error: FW error in SYNC CMD CHANNEL_SWITCH_TIME_EVENT_CMD Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu Mate 20.04, with all supplied kernels up to 5.4.0.33 I occasionally see a message on my screen that disk space is low.
