I' using Ubuntu 13.04. Two days ago I had a problem with the connectivity of the Wifi. I followed these instructions "...Now download the latest NetworkManager, in case you need to reinstall it if WICD doesn't work sudo apt-get install -d --reinstall network-manager network-manager-gnome
Then to install it sudo apt-get install wicd-gtk
And now you need to uninstall NetworkManager: sudo apt-get remove --purge network-manager-gnome network-manager.
Now you can find WICD in your menu Start WICD, find the network you want to use and enter the information needed, password, encryption, etcetera and choose Automatically Connect to this network. You should be good to go!"
But when I tried to connect to wicd: "Could not connect to wicd's D-Bus interface. Check the wicd log for error messages" and upon checking with System Testing Report I found this "Error:root: could not find def gateway info in /proc" and "Error:root: could not find default gateway by running route"
Lastly when I removed wicd-gtk and installed network-manager-gnome network-manager and tried to run "network" in the settings, it again says "The system network services are not compatible with this version"
Can you help?
