Surface P4 -Network adapter bug(frequent disconnections)

[John Ross]

After finding myself somewhat disappointed (again)with Windows 10, I decided to switch back to Ubuntu. Picking up 18.04 LTS "Bionic Beaver" - Alpha amd64 distro for my Surface 4 Pro, I got stuck with the network disconnections bug explained here; additionally, I have identified a few less problematic device issues like camera, poor sound quality, no touch screen, and no Bluetooth pen as so far. Back to the network adapter, after researching a ton of forums, I end up with this one hoping that the solution number one from Jesse will help.
I run "$ sudo nano /etc/NetworkManager/NetworkManager.conf" command and fund
[Device]
Wifi.scan-rand-mac-address = no ....in place. In desperation, I have changed it to "yes" hoping that NO might interfere with this distro only, but the results are the same as was before. Disconnections occurred as frequent as before with exactly same patterns. As I am inexperienced with Linux, I depend on your help, can anyone guide me what to do next, please?
