With those entries in /etc/network/interfaces. Very confusing: The debian documentation about Network-Manager says that "NetworkManager will only handle interfaces not declared in /etc/network/interfaces" - Source. If I move the cable back to the first port (enp5s0), it still only connects at 100mb. Why the heck would adding those two entry for enp5s0, make enp4s0 start working for the first time? Then I moved my ethernet cable to the other port and it connected at 1000mb!: So, I added these two lines hoping, even though enp5s0 was already working at 100mb: allow-hotplug enp5s0 I don't know what I'm doing! So, would appreciate advice.Īnd noticed that it contained an entry for enp4s0: allow-hotplug enp4s0 In network manager, even when I turn off auto-negotiation and manually set it to Gigabit Full Duplex, it still only achieves 100mb half duplex.

enp5s0 does connect, but it can only achieve 100mb half duplex, instead of Gigibit Full Duplex:Īctually, if I installed an actual desktop environment onto this machine, I bet the network card would just automatically work, but I've only install Awesome Window Manager alone (which has burdened me with a lot of work I normally don't have to do -work I'm struggling with) Notice that the card has two Ethernet ports.
