I edited the SD and etc/network/interfaces to uncomment the eth0 hotplug and put in the ssid and pw for the wireless. Now able to ssh through ethernet. wifi does not work.
root@DietPi:~# iwconfig
eth0 no wireless extensions.
lo no wireless extensions.
root@DietPi:~# ifconfig

Armbian uses network manager to control wifi – nmtui is the tool that they use. Dietpi doesn’t have that.
