NETWORK
Če želiš pogledat kdo in kaj je priklopen na tvojo mrežo lahko uporabiš:
sudo netstat -tupl
in tako dobiš tele podatke:

NetworkManager
is a program for providing detection and configuration for systems to automatically connect to networks. Včasih se mi zgodi, da povezava zamrzne in se ne morem povezati na internet, čeprav imam določen IP.
Navadno, ko vse dela je status od NetworkManager-ja takšen:
systemctl status NetworkManager.service

Mogoče bi poskusil resetirat NetworkManager.service ? (morda prej poglej kakšen je status)
systemctl restart NetworkManager.service
Prioriteta povezave
NetworkManager ima tudi grafični vmesnik nm-connection-editor kjer lahko nastavimo prioriteto posameznih povezav.
0je najvišja povezava
Pot, ki jo povezava vzpostavi je opisana z:
ip route get 8.8.8.8
