Ubiquiti Controller software on Raspberry Pi

$89 for a Ubiquiti Cloud Key or $59 for a Raspberry Pi complete kit… ┬áThere are plenty of examples, including the ubnt forums, for example:

This post will be updated.

Topics to include:

  • Any steps required to get UniFi controller working on a Rapsberry Pi 3 model B
  • Adopting APs that are joined to an existing controller


Outdoor Wireless Deployment

Deployed this arrangement to broadcast a wireless network from an outdoor antenna roughly 150′ from one house to another.

The ‘Indoor Extension AP’ utilizes a wireless uplink from the ‘Outdoor AP’ – and you can have multiple extension APs on the same network.

Configuration is all web-based – both devices are power over ethernet – took about 1.5 hours from start to finish (not including mounting the devices).

One very neat thing is that you can download a map via Google Maps which the software uses to estimate how the wireless reception range of each AP. It errored on the side of caution as we had a 99% strong signal (according to their own metrics) outside of the estimated range between the two APs.

The software also lets you block specific MAC addresses, keeps track of traffic by client device and many other niceties that a typical over-the-counter AP would not have.

Extending an Airport Extreme wireless network with DD-WRT

Parts used:

  • Airport Extreme w/ 7.6.3 firmware
  • Buffalo WZR-300HP running DD-WRT (factory default)

Step 1: Configure the Airport Extreme to use “WPA2 Personal” as the Wireless Security type

Step 2: Physically connecting the Buffalo router to your computer is the easiest way, if you do not have an ethernet port you can connect using a wireless link. Configure the Buffalo WZR-300HP (or any DD-WRT router) as follows:

  • Wireless Mode: Client Bridge (Routed) – this creates a secondary subnet
  • Wireless Network Mode: BG Mixed
  • Wireless Network Name (SSID): set to the same SSID as your Airport Extreme network
  • Click ‘Save’

Step 2b: Add a virtual interface by clicking ‘Add’ under the Virtual Interfaces section and configure the following:

  • Wireless Mode: AP
  • Wireless Network Name (SSID): set to something DIFFERENT than your Airport Extreme network SSID
  • Click ‘Save’

Step 3: Click on ‘Wireless Security’ and configure the following:

  • Security Mode: WPA2-PSK
  • WPA Algorithms: AES
  • WPA Shared Key: the same password you used while configuring the Airport Extreme wireless security password
    I also clicked ‘Unmask’ just to be certain
  • Click ‘Save’

Step 3b: Set the security mode and password for your extended wireless network:

  • Security Mode: Can use whatever you want, even leaving it open. I chose the same as my primary network to keep things simple.
  • WPA Algorithms: Again, you can use whatever you want, I chose TKIP+AES
  • WPA Shared Key: I set mine to the same as my primary network
  • Click ‘Save’
  • Click ‘Apply’, it will take up to 2 minutes for the Buffalo router to reboot

At this point if you are physically connected to the Buffalo router you should have internet access – you can also connect to it via the new SSID you configured and should still have an internet connection.

Extending signal strength of a Linksys WRT54G router

To extend the signal strength of a Linksys WRT54G router (all versions excluding v8 – they no longer let you replace the antenna) you can use this adapter & antenna combination:

Ideally you would also install DD-WRT and boost the power setting up from 75mW or whatever the default it. 110mW tends to be a safe number.

If you are starting from scratch, or have extra funds, I would recommend using the Buffalo WHR-HP-G300N. You can use the same 9dBI antenna without the adapter.

dd-wrt repeater with airport extreme fix


  • WPA Personal works great with an Apple Airport Extreme wireless router too. Select “WPA/WPA2 Personal” on the Extreme and “WPA Personal (TKIP)” on the bridge [dd-wrt box]. Enter the same shared key on both of course. [under Wireless tab –> Wireless Security subtab]
