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 – M. Becerra Nov 2 '16 at 17:00

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. – user439193 Dec 20 '16 at 3:56

sudo service wicd stop and then sudo service network-manager restart also works – kenn Jan 12 '17 at 17:58

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
