    Lubuntu, dsl connection dissappeared from network manager

    I'm using Lubuntu 13.04. Yesterday I managed to create a dsl connection and everything was working fine. Today, when I started my computer, by some reason, the dsl and wired connection options have disappeared from the network manager.

    I don't really know what other info should I give, so if you need some information, please just ask for it.

    I don't know if this helps, but I can remember that on my previous Ubuntu installation, I had big problems with the wired, and finally I managed to fix them by deleting 'dns=dnsmasq' from some file, as was proposed somewhere in the internet. On my new Lubuntu, I couldn't find this file, where dns=dnsmasq is, but now I see it is in the last file (/etc/NetworkManager/NetworkManager.conf).

    Re: Lubuntu, dsl connection dissappeared from network manager

    The /etc/network/interfaces file is a separate thing from network-manager (they are separate Unix services) - any time you define interfaces/connections in that file, the default behaviour of network-manager is to ignore them, as indicated by the '[ifupdown] managed=false' in the /etc/NetworkManager/NetworkManager.conf file

    You could set [ifupdown] managed=true HOWEVER the two services often don't 'play nice' together - if you really want to use NetworkManager, you should set up everything (except the 'lo' loopback connection) via NetworkManager - I've never done that for a DSL connection but the options are all there for it
