Random disconnects on Wifi on Linux Ubuntu 18.04 laptop with a Dual Band Wireless-AC 8265 module - message is "deauthenticating from...by local choice (Reason: 3=DEAUTH_LEAVING)"

Jump to solution

The Wifi randomly stops with the above message in the logs.

The company who sold me the laptop has replaced the WiFi module - so it seems not to be a hardware problem.

I have modified the /etc/modprobe.d/iwlwifi.conf file and added

options iwlwifi bt_coex_active=0

but it didn't change anything.

However I noticed that after higher activity (watching TV live) the Wifi is disconnected more quickly than when no activity is performed (excepting system activity: checking if new packages are available, if mail has arrived,...).

Generally if I am watching TV (using a streaming application like https://www.molotov.tv/) in 10-20 minutes the Wifi is cut, while doing nothing it may keep the WiFi even more than an hour.

What should be done? what options may I activate to gather more information?

 

netdriverinfo.sh script displayed the following information:

: 02:00.0

   Make/Model = Intel Corporation Dual Band Wireless-AC 8265

   Ethernet controller = Intel Corporation Wireless 8265 / 8275

   VenID:DevID = 8086:24fd

   Driver name = No driver loaded

   Driver version = No driver loaded

 

dmesg displayed the following messages concerning the iwlwifi module

```

I shall try to install Windows to see if the problem persists there - or maybe I shall try firstly to run Ubuntu or another live distribution from a CD/DVD to see if the problem persists. I don't think is the router - other computers or smartphones using the same router do not exhibit this problem.

If I understand correctly, among all Linux driver's options there is none to be used at least to get more information when disconnecting ?

Take it back to the company that sold it to you.

The company in question has already replaced the module, I don't think 2 different modules may experience the same hardware problem, it should really be a very strange coincidence.

Try to ask this question on Linux Ubuntu forum. Probably you did already, however, it is O.S. or Router problem.

I tried, but none of the solutions found worked for me! :-(

  1. Try to update the Ubuntu to newer/latest version.
  2. Backup your drive and install Windows. Check if this problem exists with Windows.

Yes, that was a good clue, and I thank you very much for it.

So, using a live Xubuntu 19.10 DVD I did not experience any network cut, so I may presume that is something different.

And in fact coming back to my normal Ubuntu installation I noticed a program "recommended" by the company that sold me the computer - deleting it (tuxedofancontrol) made my computer more usable ; in fact, in order to cut the network now I have to use my TV stream program and run glxgears at the same time to stress the CPU (the fans are working, even without tuxedofancontrol). But... more rarely, there are some network interrupts! :-(

The biggest difference with respect to Xubuntu 19.10 is the kernel version - I even noticed that the latest kernel version (5.4.7) has in its changelog a fix for iwlwifi! (see https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.7).
