(Posting this for future reference.)

Since installing linux headers 6.11.0-17-generic on Ubuntu the network error "Cable unplugged" appears -- in Ubuntu Settings > Network > Wired -- when waking from system suspend.

sudo systemctl restart NetworkManager does not make the problem go away; a reboot does but that's rather tiresome.

Ubuntu Settings > System > About says,

  • Operating System: Ubuntu 24.04.2 LTS
  • Hardware Model: ASUSTeK COMPUTER INC. NUC14RVK-B
  • Processor: Intel® Core™ Ultra 5 125H × 18
  • Firmware: RVMTL357.0038.2024.0115.1528

The problem is the subject of ASUS support FAQ 1053497: "[NUC] Unexpected loss of LAN connectivity on ASUS NUC 14 Pro/Pro+". The FAQ says to "Upgrade the BIOS to version 0041 or later to resolve". A BIOS update is available here, and the NUC14RVKU5 has an ASUS support page here.

As a temporary fix (without rebooting) run sudo modprobe -r -v igc; sudo modprobe -v igc where igc is the driver name from the output of sudo lshw -C network (the line starting with configuration:). At my end the 2 modprobe commands bring the network back in 5 to 7 seconds. Credit for this fix goes to totedati for this answer.
