Excerpt from journalctl

This problem makes my wifi connection unusable since one of the recent updates in Leap 15.2, unfortunately I am not sure which exact update introduced it: The connection is interrupted very often with errors as in the attached logfile (excerpt from `journalctl -f`), sometimes every minute or even more often. NetworkManager automatically seems to recreate the connection, but it can be very annoying.

The device is a ThinkPad X240 with network controller Intel Corporation Wireless 7260 (rev 83). It seems to be the same problem as reported in this upstream bug:

You can try to try the old kernels available in 15.2 update channel.  I'd start from Leap 15.2 GA kernel and confirm whether the issue is still seen or not, while keeping the rest.

Also, did you try some power-saving options mentioned in the upstream bugzilla?

Thanks for reminding, I eventually tried all the older kernels that are available from the Leap update channel, unfortunately without success and the problem was there with all of them. I am quite sure that this was not an issue with Leap 15.1, but IIRC 15.1 was still based on a 4.x kernel.

Meanwhile I migrated the laptop to Tumbleweed, hoping that there are more frequent updates that might eventually fix the problem, but so far it is still happening with the current `5.9.12-1-default`.

Yes, I tried all of these options, but unfortunately it seems none of them actually had an effect as other people also reported.
