Connection activation failed (2) Active connection removed before it was initialized
The ubuntu version is 16.04 My network is working fine until a particular point. After that, it got automatically disconnected. If I tried to connect to the wifi again it shows the following prompt every time.
I have tried to restart the network manage usingsudo service network-manager restart command, but it doesn't work.
The only solution is reboot the system every time. Sometime It is not showing the wifi option in the top.I am tired of reboot the system every time.
I don't find any solution in askubuntu for this problem. Could someone help me to resolve the issue.

Go to Preferences->Network Connections. Remember all the proper settings of current connection - you will need to rewrite it. Then delete connection and add it again. It worked for me on VirtualBox Lubuntu machine.
My words might not have the cure to your issue, but, from the error message, it seems that something is eating your internet link.
This usually happens with either a malfunctioning network card, or a really bad network card driver!
Otherwise, something on your system is interfering with your NIC software and/or Network Manager? A firewall/antivirus, perhaps?
