Public bug reported:

my hardware : laptop Asus N751JK Network controller: Qualcomm Atheros
AR9462 Wireless Network Adapter (rev 01) Subsystem: AzureWave AR9462
Wireless Network Adapter

I was runing Ubuntu 20.10, 21.04 up to Ubuntu 21.10 with Kernel 5.13.0 without 
any problem.
When migrated to Ubuntu 22.04 which installs Kernel 5.15.5 then the problems 
started.

I upgraded and tested unsuccessfully the following Kernels : 5.15.28,
5.15.36, 5.16.14, 5.16.20, 5.17.4, 5.17.5

I disabled the power save as explained at 
https://askubuntu.com/questions/1403773/22-04-wifi-keeps-disconnecting-for-a-few-seconds-frequently/1404471#1404471
without improvement in any of the Kernels tested.
Also the "intel_iommu=off" mentioned at 
https://groups.google.com/g/linux.debian.kernel/c/RFpPIp0cncA/m/v9ELDxLICgAJ 
Bug#994590 didn't help.

I downgraded and currently running without any problem using the Kernel 
5.13.19-051319-generic.
Kernels 5.15.0 and 5.15.4 also runs ok

There is no problem in my airpoint (router) nor my internet access, I have 
other different computers and devices working correctly on wifi.
In addition my N751JK works correctly when using the Ethernet adapter for the 
physical cable.

seems to be something between 5.15.4 and 5.15.5 that is also propagated
to 5.16.x and 5.17.x
