WOL with tp-link TG-3468 on Ubuntu 18.04.3

I'm putting this here for my own reference because I was up way too late figuring this out.

After installing the network card, I could see I already had the right driver for it. sudo lshw -c network showed that the card was disabled though. What ended up getting the card working was the following which I recorded here:

sudo ip l s dev enp6s0 up

Then I modified /etc/netplan/01-network-manager-all.yaml to look like this:

network:
  version: 2
  renderer: NetworkManager
  ethernets:
    enp6s0:
      match:
        macaddress: "12:34:56:78:90:12"
      set-name: enp6s0
      dhcp4: true
      dhcp-identifier: mac
      critical: true
      nameservers:
         addresses: ["<LAN IP address of router>"]

Then

sudo netplan --debug generate
sudo netplan apply
sudo reboot

That got the card working correctly. Then the instructions on Ubuntu's WakeOnLan page worked seamlessly for me to get Wake-on-LAN.
