h1. How to configure ubiquiti network equipment
h2. General steps
* Reset the device
* ssh into it (username: ubnt, password: ubnt)
* Setup a password
h2. 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)
h2. Enabling ssh access without a password
* Add your public RSA (ed25519 don't work) to /etc/dropbear/authorized_keys
h2. Configuring Wifi
* Download the "unifi network" app
* Go to account->standalone devices : wait for the aps to show up
h2. 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.
* Update ("downgrade") to firmware version 3.7.58
** https://dl.ui.com/unifi/firmware/U7PG2/3.7.58.6385/BZ.qca956x.v3.7.58.6385.170508.0957.bin
* Get the latest openwrt image
** Check https://openwrt.org/toh/ubiquiti/unifiac
* Use mtd to replace it
* Use mtd and to erase kernel1
* Set zero the boot loader to 0
** write a 0 o the mtd partition "bs"
