Hey Joe, If you want to continue troubleshooting your built-in Ethernet, try:
sudo ip link set enP1p3s15f0 up sudo dhclient then: ip link show enP1p3s15f0 If it still shows NO-CARRIER, this could mean no cable is plugged in or driver/firmware issue. Try: dmesg | grep -i eth or dmesg | grep enP1p3s15f0 and see if there's any messages about the kernel complaining about firmware.
