Ubiquiti Unifi is scalable and has a linux controller software, meaning you only need to buy APs and a PC with linux on it (ubuntu recommended) to run the network.

The UAP-Pro can handle 200 concurrent clients and the UAP-LR / LR / UAP-Outdoor can handle 100 simultaneous clients.

The UAP's are very cheap.

There are still some problems apparently though.

Installing the controller on Debian

This needs to run under a desktop environment, so make sure you have one.

echo 'deb http://www.ubnt.com/downloads/unifi/debian stable ubiquiti' | /etc/apt/sources.list.d/100-ubnt-unifi.list
wget -O /etc/apt/trusted.gpg.d/unifi-repo.gpg https://dl.ubnt.com/unifi/unifi-repo.gpg
apt update 
sudo apt install unifi

Then

systemctl enable unifi
systemctl start unifi

visit the controller software at http://localhost:8080

You may need to change the ports

Migrating from another controller on another PC

If you are not changing hostname / IP

  1. Make sure both controllers are the same version (ie update them both)
  2. if necessary upgrade the firmware on the controllers
  3. make a backup to an .unf file of the old controller
  4. Visit the new controller (using the applet or the website) and restore from a previous backup


If you ARE changing hostname / IP

  1. Make sure both controllers are the same version (ie update them both)
  2. if necessary upgrade the firmware on the controllers
  3. make a backup to an .unf file of the old controller
  4. Visit the new controller (using the applet or the website) and restore from a previous backup
  5. On the old controller
When I move the controller, I just go into the GUI on existing controller, under SETTINGS, CONTROLLER, and change the Controller Hostname / IP to the NEW IP ADDRESS, (removing unifi.yourdomain.com) and then check the box "Override inform host with controller hostname/IP" 

Since I have the migrated controller up and running already on the NEW IP ADDRESS, after I shut down the OLD CONTROLER, the new one immediately starts provisioning the WAPS.

An alternative method is to SSH to each AP and use set-inform to point them to the new controller

set-inform http://IP.ADDR.OF.Controller:8080/inform

set-inform, adopt, set-inform a second time.

If you forget the syntax, 'help' will help

files

/var/lib/unifi/data/system.properties

if this doesn't exist

java -jar /usr/lib/unifi/lib/ace.jar discover

/usr/lib/unifi/logs/server.log

/usr/lib/unifi/logs/mongod.log
