Hello,
I have been messing around with a few orange pi's. Mainly to run an IoT device and manage it with snap's and ubuntu core. However it seems that wifi isn't working inside the ubuntu core image that is on the download page : http : / / www.orangepi.org / downloadresources / 

ip link lists:

 

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1

    link/sit 0.0.0.0 brd 0.0.0.0

3: ip6tnl0@NONE: <NOARP> mtu 1452 qdisc noop state DOWN mode DEFAULT group default qlen 1

    link/tunnel6 :: brd ::

4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000

    link/ether 02:42:c4:84:3a:4c brd ff:ff:ff:ff:ff:ff

Hi. Those images have nothing to do with Armbian. Those are the orangepi images. And these are all very bad and unusable.
Did you try Armbian images for your boards? https://www.armbian.com/download/?tx_maker=xunlong
Which orange pi boards do you have?
The Orange Pi 3 with the H6 doesn't yet have a good working image.
