[SOLVED] Network Interface Failed, Wireless Device Missing

After starting a package update but choosing not to install when prompted then suspending the laptop, the network interface failed to load on wakeup.

ip link returns loopback and nothing else.

lspci -k lists no network device.

What is the best approach you to fix this issue in which the network hardware device is unresponsive?

This may not be the best approach, but I would look at dmesg and/or journalctl to see if there is a related message. Then run lsmod to see if the module for your network device is loaded and run modprobe <module-name> to add it back if it is missing. If loaded (or after you reloaded it), try systemctl restart systemd-networkd to restart networking.

If the above doesn't work and assuming you weren't mid update, a reboot should cure the issue.

Re: [SOLVED] Network Interface Failed, Wireless Device Missing

Thanks for the input! Running lsmod didn't pull up anything that I could identify with the network device other than an entry for iptables and loop. No problem, though, because a systemctl restart got it to boot back properly. I guess a hard restart was all it needed.

Thanks!
