UniFi 2.4.4 is a stable/maintanance release. It aims to fix issues that were reported against the 2.3.9 and before. We will keep maintaining V2 until V3 is stable.

Release Note

  • fix a issue (especially for UAP-Outdoor or Pico in high-interference environments) where AP stops accepting clients as their perceived signal drops
  • fix AP appers disconnected while still serving clients in certian environments
  • fix guests get redirected back to login page when controller's time differs from AP time
  • fix map uploading issue in some scenarios
  • fix UAP-AC (US version) 5G radio issue introduced in 2.4.3
  • fix 4th ssid with vlan not working issue

How to perform the upgrade

For Debian-based system, simply do

sudo apt-get update
sudo apt-get install unifi

How to downgrade?

Make sure you have a backup of prior version. After downgrading the controller, you can downgrade the AP firmware.
