Ubuntu MATE 16.04 DSL WIFI problem cannot connect to internet

Support & Help Requests
1

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?

I found out from other sites that the problem with wlan and wifi is a bug in MATE and it would be fixed in the near future. So for the moment i prefer Ubuntu to work without problems. Thanks for help.

I just down loaded Ubuntu Mate 16.04 and had the same problem. This is how I solved it. I down loaded a copy of Ubuntu 16.04 from my desk top and put it in my Aspire laptop which has Mate 16.04. my problem child, Booted it up so I could try it on my laptop. Clicked try not install and was able to go on line with it. Checked my emails and a few web sites. Shut down and removed the disk. Powered up my laptop and was able to go on line.

There is more than one way to skin a cat.
