Ubiquiti changed wireless uplinking in UniFi Controller version 5.7.20, and are obviously still catching up on documentation updates as the steps provided in this article are out-of-date, and this one doesn’t really cover the steps needed to setup a new wireless-connected AP.

Here’s what worked for me:

1. Adopt all access points as per normal, while they’re wired.
2. Enable wireless uplink in the controller site configuration.
3. Enable wireless meshing on any APs which will be islands while they’re still wired to the network. (Device configuration → Config → Wireless uplinks → “Allow meshing to another access point”. That setting should not be enabled on any APs which will remain wired.)
4. Then disconnect and relocate the wireless APs to their final locations.
