This question already has an answer here:
I'm trying to replace the default network manager with wicd. Wicd installs fine, but there is no notification icon, and the default network manager is not disabled. If I log off my wifi using the default network manager and log on using wicd, I cannot access the internet.
Using ps -e I can see that both Network Manager and Wicd is running - should they both be running?
Wicd is set to start at boot, but I don't see it, when the computerstarts. Do I need to do something else than just install Wicd to replace the default manager? Should I apt-get remove the default manager? I have really skow wifi, and after to computer sleeps, I loose the connection completely.
So what Im looking for is a complete replacement of Network Manager to make my connection a lot more stable.
The possible duplicate suggested by Huckle applies to older versions of Ubuntu.
I'm running Ubuntu 16.04 LTS.
Thanks for any help
