I have problems with Internet connection with most Ubuntu DEs, except KDE - network managers don't allow me to establish a DSL PPPoE connection.

So I'm thinking to buy a router - conventional, I don't want a WiFi router, to take the task of performing the PPPoE connection away from the desktop.

My Internet cable which goes into my apartment has RJ-45 connector, which I plug in right into Ethernet port of my PC, no other devices being used.

I used to do it by creating DSL connection with 'pppoe' in the service field, typing password and login. Also I could use pppoeconf command for that isn't available anymore for last *buntu releases. Some people told that it's not really not DSL, so may be I just should establish different type of connection somehow.

Such issue with DSL ppoeconf is in: *buntu (GNOME3,XFCE,Ubuntu Mate) (except KDE) 16.04/18.04/18.04.1/18.04.2/18.04.3, though it works from live-usb.

    It seems it's more about hardware/software not related to Ubuntu. – R S Dec 5 '19 at 8:17

    @Melebius my cable has RJ-45 connector. I plug it into network card of laptop. My idea was that instead of establishing DSL pppoe connection in Ubuntu, I could select wired ethernet and let router deal with DSL pppoe. As one guy on superuser told me: "take it away from OS". Come on people, is it gonna work or not, decide already ) ? – R S Dec 5 '19 at 10:35

    @Melebius I established connection with the same DE's, but noticed that one *buntu release does it, next doesn't, next again allows me to do it, next doesn't and so on, but nowadays it seems they firmly decided to make it bad ). So DE does affect it, it's a bug - there connection appears that I didn't established - autoethernet instead of what I were setting up. In the old days that wasn't big issue as I could use pppoeconf. But console doesn't help anymore - there is no pppoeconf package anymore for last versions of *buntu's. – R S Dec 5 '19 at 16:50

    So, your connection is not DSL, it is Ethernet,. Who is the ISP providing your Internet connection? If you don't know, if that's hidden from you, please go to ipchicken.com and tell us the external IP address if finds. Which releases of Ubuntu have you used with which DEs? Please don't respond with Add Comment as those will overflow soon; instead, please respond by clicking edit and put your response in the question itself. TY. – K7AAY Dec 5 '19 at 17:14

    @Pilot6 The OP has a genuine need for help with an unusual Internet configuration which requires PPPoE even though he connects his Ubuntu PC by Ethernet directly to the wall jack in his apartment by RJ-45 cable. – K7AAY Dec 5 '19 at 18:38

Operating systems doesn't care what operating system the router uses. The standards are open and vendor-neutral. In general the relevant standards are:

  • Ethernet for providing physical connectivity. The NIC in your computer has to be supported by the OS you're using, but every Ethernet card can talk to all other Ethernet devices, generally speaking.
  • IPv4, the most-common protocol today on the internet. This is well supported by Linux, and most other modern operating systems.
  • IPv6, the next generation Internet Protocol, with increased address space to accommodate more devices on the Internet.

When it comes to configuration, the software used by Mikrotik, winbox, is only supported on Windows. It is purported to be well supported in Wine. I also believe mikrotik devices have a command line interface which can be used.

  • Or I could boot in Windows set it up and switch to Ubuntu. – R S Dec 4 '19 at 19:34

    Yes, MikroTik devices can be controlled by command line interface via SSH and they also offer a web interface called WebFig, visually similar to Winbox. – Melebius Dec 5 '19 at 8:45

    Naah most of the times all you need is a browser and a utp connection. The latter is only for the initial setup – Rinzwind Dec 5 '19 at 12:34
  • @Melebius Ok, thanks. I have only used winbox with Mikrotik at work, so I decided to add that I was not certain about this aspect :) – vidarlo Dec 5 '19 at 18:06

    @RS Switches can't do PPPoE for you, typically. As you want it to terminate a PPPoE connection, you'll need a device which speaks PPPoE. – vidarlo Dec 5 '19 at 18:30

It's possible to bypass this problem using nmcli command.
Create connection:

nmcli con edit type pppoe con-name "Connection name"

Set a username:

set pppoe.username <username>

Set a password:

set pppoe.password <password>

Save and quit:

save
quit

And this connection going to appear in the Network Manager.
