Ubiquiti

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.

Unifi UAP

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.

Press apply changes on the bottom. You should see the new controller status of the APs changing to connected.

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

The UI is slightly confusing as there are buttons on the top, bottom, middle and at the bottom. Also, logging only starts once you log in, so the dashboard and traffic analysis only start once you are logged on.

Basic system configuration

After running the wizard, basic system configuration can be done by clicking the System button on bottom left. This is where you can backup and reboot but also add extra DNS servers to the system.

Config Tree

The config tree allows you to click on the triangles to expand AND view what is in the config (meaning you have to double click on the triangle quite a bit), hover over the name of the config for some more information and the + or - to install or uninstall a service. If you are going to uninstall a service it will show in red.

DHCP

Services (top) -> DHCP Server

Once you have added a DHCP server you can configure it by clicking on Actions on the right of the screen and then View Details.

There are also options under Service -> dhcp-server in the config tree

DNS

To see what nameservers are being used to resolve

  cat /etc/resolv.conf
