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version 5.7.20, and are obviously still catching up on documentation updates as the steps provided in this article are out-of-date, and this one doesn’t really cover the steps needed to setup a new wireless-connected AP.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:
- Adopt all access points as per normal, while they’re wired.
- Enable wireless uplink in the controller site configuration.
- 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.)
- Then disconnect and relocate the wireless APs to their final locations.
