UniFi Isolated Devices

A UniFi AP will become "Isolated" if it loses connectivity with the UniFi Console on its management network/VLAN, but can still be detected by another "Online" AP. Often times, clients connected to an isolated AP will work as normal because the AP will continue running using its last known configuration. 

Wirelessly Meshed APs

If the isolated AP was previously connected via a wireless mesh, follow these steps:

  1. Move the APs closer together. A device may become isolated when there isn't sufficient signal strength.
  2. Factory reset the isolated AP by holding the power button for 10 seconds, or until the light begins flashing.

  3. Remove the isolated device from the UniFi Network application in UniFi Devices > select the AP > Settings > Remove
  4. Re-adopt the device.
  5. If the problem persists, hardwire the AP into your network and update the AP to the latest available version.
  6. Repeat steps (2)-(4).

Wired APs

If the isolated AP is hardwired into your network, follow these steps:

  1. Revert any recent changes to switch ports, subnets, or firewall rules. It's likely that this interrupted connectivity.
  2. Follow the detailed instructions here.
  3. Factory reset the isolated AP by holding the power button for 10 seconds, or until the light begins flashing.

  4. Remove the isolated device from the UniFi Network application in UniFi Devices > select the AP > Settings > Remove
  5. Re-adopt the device.
  6. If the problem persists, we recommend temporarily establishing a wireless mesh connection to the AP while you further investigate step (2). More details can be found in the UniFi Network - Wireless section here.
