Why has the option of adding a DSL connection on the tab for Wired Connection been removed after 17.04?
I was using 16.04, and then upgraded to 17.04 and later 17.10, I still had the DSL connection, as it was saved from previous versions.
However, on a fresh install of 17.04, 17.10 or 18.04, I cannot create DSL connections anymore. In my opinion this is a important feature, as many Indian ISPs with many customers still use DSL.
For an average user who has a single device it's easier to create a DSL connection, and put the DSL modem in bridge mode, to avoid hassle of port forwarding.
