I installed the future ubuntu 17.10 and found the same problem. Searching I found the following solution:
1) To stabilize the device: $ Sudo apt install dnsmasq-base $ Sudo service network-manager restart 2) To correct authentication error: $ Sudo nano /etc/NetworkManager/NetworkManager.conf Add in the end: [Device] Wifi.scan-rand-mac-address = no $ Sudo service network-manager restart After this procedure, it worked perfectly. I consider the solution provisional and I hope they will correct it soon.
