Wireless network with wpa2-psk


From syslog:
... everything fine and then:

... and then normal again.


This happens a lot -- around 20 times a day.
The PC is in a warm environment but the occurrences do not seem to be related to the times of higher temperatures:
15:14:55
15:23:01
15:45:55
16:49:55
17:17:51
17:41:55
19:47:55
20:37:55
21:57:55
22:19:55
01:37:55
03:37:55
03:51:14
04:49:34
05:39:35
06:21:15

Any ideas?

Please try to run it on Linux Mint.
You can try it on Live USB first.

If the situation will continue we will escalate the debug.
