How to configure ubiquiti network equipment

General steps

  • Reset the device
  • ssh into it (username: ubnt, password: ubnt)
  • Setup a password

Upgrading most ubiquiti access points

  • Dowload the latest firmware from https://www.ui.com/download
  • scp it to the device as /tmp/fwupdate.bin
  • ssh into the device, run
    • syswrapper.sh upgrade2 &
    • Seems to need to be backgrounded from all examples in the web - it instantly exits though
    • so & might-or-might-not be necessary

Enabling ssh access without a password

  • Add your public RSA (ed25519 don't work) to /etc/dropbear/authorized_keys

Configuring Wifi

  • Download the "unifi network" app
  • Go to account->standalone devices : wait for the aps to show up

Installing OpenWRT on AP Lite/LR/Pro

Stock ubiquiti does not work in IPv6 only environments. So replacing the stock firmware with OpenWRT makes them usable.
