I report that before I even start the kernel changes as recommended, I removed my wireless PCI card, to test the system and analyze it could be the reason for the problem.
It resulted that: After the removal of Wireless PCI D-Link DWA-520, the system worked perfectly with no crashes, then being proven cause of the problem. What puzzles me is that the system itself has identified the hardware and installed the correct driver. It should work without crashing! I tried to install a USB Adapter TP-Link Archer T2U, the system did not recognize, and also I could not install and put into operation, to replace the D-link.
