Ubuntu installation configuration network

Sudo pppoeconf

Pon dsl-provider

Poff

Input at the terminal

Sudo gedit / etc/ppp/options

Change lcp-echo-failure 4 to lcp-echo-failure 40 in the pop-up document because there is an obvious flaw in the default setting of Ubutnu. The number of lcp-echo-failure is set to 4 and lcp-echo-interval is set to 30 seconds. In other words, if the ADSL server does not return the echo-reply signal within 120 seconds, Ubuntu will think that there is something wrong with the network and immediately break the reconnection, which makes people very unhappy.
