As the title states, I'm having trouble getting a wired connection after suspend on my laptop. For reference, here is my card (using the r8168 driver):

Jul 12 12:01:38 archbox NetworkManager[3825]: <info> Activation (enp2s0) starting connection 'enp2s0'Similarly, running 'sudo systemctl restart NetworkManager' doens't help as I only get a wifi connection. Journal messages are pretty much the same as above. I'm trying to determine if this is a driver issue, but I don't see anything relevant in the journal. I've seen a couple of bugs on the Debian bug tracker https://bugs.debian.org/cgi-bin/bugrepo … bug=743206. That one appears to be solved as " network-manager 0.9.8.8-6". I currently have 0.9.10.0-1.
Interestingly, sometimes when I try and restart networkmanager from gnome's menu, I see
dhcpcd[8545]: dhcpcd already running on pid 8330 (/run/dhcpcd-enp2s0.pid)After running 'sudo systemctl stop NetworkManager' followed by 'sudo killall dhcpcd' and 'sudo systemctl start NetworkManager' I get wifi but no wired connection. Anybody have any ideas?
EDIT: Any suspicions against dhcpcd are unfounded as behavior using dhclient is not much better. After wake-up I apparently do have a wired connection, but pings to 8.8.8.8 and www.google.com both fail. Restart networkmanager using systemctl does not work as with dhcpcd. Stopping networkmanager, killing all dhclient processes and restarting networkmanager do restore my connection to the internet though. Sorry for my scatterbrained attempt at troubleshooting this. My difficulty here is pinpointing an exact sequence of steps that results in consistent behavior. So far, after waking from sleep any of my above attempts at getting a network connection have varying degrees of success and failure.
