- 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.

+ When migrated to Ubuntu 22.04 which installs Ubuntu Kernel 5.15.0.x (which 
corresponds to Mainline 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

+ 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 Kernels
- 5.13.19-051319-generic or 5.15.0 or 5.15.4
+ I downgraded and currently running without any problem using the Ubuntu
+ Kernels 5.13.19-051319-generic or Mainline Kernels 5.15.0 or 5.15.4
  
  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
