Im unable to access network indicator because "Device not ready" issue, this problem happened after reverting back to NetworkManager from wicd network manager thanks to this method.

The odd things is, I could connect to wireless connection, unlike most people that cannot connect through WiFi because of this issue.

  • No worries. While reverting the process to get back the Network Manager, did you follow this step by step? help.ubuntu.com/community/NetworkManager

You can restart your device as it may solve your problem. Instead, you can also use try restarting your network services:

sudo systemctl restart network-manager

    Except this long standing virus of Ubuntu and Linux in general has evolved immunity against that antidote. The restart no longer works

Have you tried removing unused package that comes with wicd ? If no, consider removing it by running autoremove command:

sudo apt-get autoremove

    Thanks ! I didn't think autoremove will solve the problem.

    sudo service wicd stop and then sudo service network-manager restart also works
