I just have installed Ubuntu Mate 16.04 and the connection to Internet is impossible. I create a DSL connection everything is ok but after i try to connect i cannot. Wifi is missing, i cannot install drivers from section Other devices. I try to connect via ethernet port. I tried sudo pppoeconf but this command returned nothing, is missing ppoe. I tried to install deb package, but nothing, the command is not working.
I edited interfaces from Network, but nothing, internet connection is broken in 16.04.
Any way to fix this thing?
