wifi frequently crash and restart

[ElricX]

I have a wonderful Almond + router and I am very satisfied with it EXCEPT that the WiFi has been crashing frequently for some time. I noticed this because my Google Nest hub which is in the living room displays a network error at this time and about 30 seconds later the wifi comes back functional. The problem is for the 2.4 and 5 GHz band. I attempted a factory reset of the router without success.

I looked in the log files and for me it is incomprehensible!

After a look in the router log I have see some message about wifi service restarted and DNS rebind attack. I don't know if these 2 message are linked.

My router is:

Router Model Almond +
Firmware Version AP2-R093-L009-W016-ZW016-ZB005
Kernel Version 2.6.36
Local Time Mon Sep 14 18:46:45 2020


Thank a lot for your help!

I will answer to myself, the problem was caused by a new laptop connected on the wifi. It use wifi6 driver and the drivers doesn't handle well the wifi security protocol. We must set to Force CCMP AES only in the Cipher parameter.
