Ethernet won't connect (18.04.2)
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I left my computer running for an hour or two, idle, and when I logged back in, the ethernet connection was stuck on "connecting." I should probably mention that I installed some tools with Katoolin, which may have messed with my network settings. What steps should I take, beyond router reset, unplugging/replugging the cable, and restarting network-manager? Thanks!

Have you checked to ensure the connection isn't still there? Sometimes the UI gets confused and says connecting when it's established. Runifconfig -ato check and see if the Ethernet interface has an IP address. Also, what version of Ubuntu are you on?

Ifconfig spits out a value for inet6 but no recognizable ipv4 address.

Have you checked to ensure the connection isn't still there? Sometimes the UI gets confused and says connecting when it's established. Run
ifconfig -a to check and see if the Ethernet interface has an IP address. Also, what version of Ubuntu are you on?– Minty

Apparently, the system wasn't loading the network driver, so the interface wasn't detected. sudo modprobe r8169 appears to have fixed it.
