h1. How to configure ubiquiti network equipment 

 {{ toc }} 

 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 to erase kernel1 
 * Set the boot loader to 0 
 ** write a 0 o the mtd partition "bs"
