How to perform the upgrade

We're being more cautious in pushing releases to the world. Following Google's model, we'll have three release channels

  • stable (widely used, most stable)
  • rapid (soaked in beta for a while)
  • beta (cutting edge)

For Debian-based system, simply do

sudo apt-get update
sudo apt-get install unifi-rapid

How to play safe?

UniFi stores everything under <UNIFI_BASE>/data/ . Keeping a copy will get your base covered. You can even install the new version, stop it, copy the data/ over it, and restart the controller.

How to downgrade?

The DB schema is drastically different and downgrade is not possible. Make sure you have a backup of prior version. After downgrading the controller, you can downgrade the AP firmware.

Known Limitations

  • UAP-AC - Rogue AP detection will only search for rogue AP on first power up. It will not continuously update rogue AP list during runtime.
  • Zero Handoff not supported on UAP-AC yet. Currently in development.
  • Wireless Uplink not supported on UAP-AC yet. Will be release as an alpha and by invitation only in the next few weeks.

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
    # or over HTTP by using hkp://keyserver.ubuntu.com:80
  3. update, install, and upgrade
    # retrieve the latest package information
    apt-get update
    # install/upgrade unifi package
    # there are 3 packages in the same repository 
    # . unifi       (the most stable)
    # . unifi-rapid (soaked beta/rc/stable)
    # . unifi-beta  (the cutting edge)
    # you can install / switch between them
    apt-get install unifi-rapid


A shell library, unifi_sh_api is provided with the release. here's a sample script to authorize a guest for 30 minutes

## define required variables
## include the API library
. unifi_sh_api
# authorize a client for 30 minutes, limit down/up speed to 2048/1024kbps, quota is 500MB
unifi_authorize_guest "e8:17:22:10:5d:4d" 30 down=2048 up=1024 bytes=500 
# generate 10 voucher(s) valid for 60 minutes, limit down/up speed to 2048/1024kbps, quota is 500MB
unifi_create_voucher 60 10 down=2048 up=1024 bytes=500
# this returns you a token that you can call by using unifi_get_vouchers()


  1. AP->Performance view is experimental. Currently it shows what the radio is doing by red (packets not sent because of likely interference) / yellow (packets retried) / green (packets sent)
  2. voucher.css and voucher.html, at data/sites/SITE_NAME/portal/bundle/, is where you can fully customize your voucher.
  3. If you have existing customized guest portal, make sure to change form="/guest/login" to form="login" - let the relative path take care of per-site URL
  4. For API access, you pretty much need to insert /s/SITENAME into the URL. (after login with an admin in for site)
