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 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 propagates to 5.16.x and 5.17.x
