 +====== Netplan WiFi Bond ======
 +While playing with Ubuntu on a HP T520 thin client, I found there was built in WiFi. As I often use these devices for hosting services (Home Assistant, Pi-Hole, etc), having the WiFi interface as a redundant connection was appealing. The first attempt ended in disaster when I dropped the box off my Dad's home network and locked myself out. A second attempt revealed the following configuration to work well:
 +
 +''/etc/netplan/01-netcfg.yaml''
 +  
 +<file>
 +network:
 +  version: 2
 +  renderer: networkd
 +  wifis:
 +    wlan0:
 +      dhcp4: no
 +      dhcp6: no
 +      access-points:
 +        "SSID":
 +           password: "password"
 +  ethernets:
 +    eth0:
 +      dhcp4: no
 +      dhcp6: no
 +  bonds:
 +    bond0:
 +      dhcp4: yes
 +      dhcp6: yes
 +      interfaces:
 +        - wlan0
 +        - eth0
 +      parameters:
 +        mode: active-backup
 +        primary: eth0
 +        fail-over-mac-policy: active
 +        mii-monitor-interval: 200
 +        up-delay: 200
 +</file>

 +This works very reliable, with a minimal fail-over time between Ethernet and WiFi. For services that rely on a consistent IP address (and in come cases consistent network interface, ie DHCP) this a good solution.
