Ubiquiti UniFi Outdoor Plus

The UniFi Outdoor Plus is an 802.11b/g/n weatherproof outdoor access point. Exclusive feature is a configurable RF filter in the receive path that should allow better sensitivity in noisy environment.

Reverse engineering the control protocol of the filter is currently being worked on. Without a correctly programmed filter, the access point is deaf and therefore not usable

Installation

Install OpenWrt (generic explanation)

An unconfigured device gets its IP address via DHCP, Login username and password is 'ubnt'. Once the device has been adopted by a controller, it will use the device password of the 'Site config' page. Use ssh to login.

  1. Login
  2. possibly backup the stock firmware using
    dd if=/dev/mtd2ro of=/tmp/jffs.img
  3. scp /tmp/jffs.img to your backup location, rm /tmp/jffs.img from the device to save memory
  4. Download the factory.bin image as shown above
  5. scp the image to the /tmp directory of your device
  6. Install OpenWrt using
    fwupdate.real -m openwrt-ar71xx-generic-ubnt-unifi-outdoor-plus-squashfs-factory.bin -d

Upgrading OpenWrt

Revert to stock firmware (untested)

You can flash the backup image optionally created before first installation. Note that the configuration partition of the stock firmware is not touched by OpenWrt, so you will also revert to the config used before OpenWrt.

  1. scp your backuped jffs.img to /tmp
  2. ssh into the device
  3. Revert using
    mtd write /tmp/jffs.img firmware -r

Also look at the debricking section.

Basic configuration

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

Specific Configuration

Wifi power

Total gain by antenna and tx amplifier is about 10-11dB, amateurish measured. ath9k doesn't know about this and so doesn't OpenWrt. So if you configure 18dBm transmit power, you'll actually get 28dBm, well outside regulatory limits! For Europe, do not set transmit power beyond 10dBm. As the access points also needs the hear the devices associated to it, one sided transmit power boost would not help with range extension anyway.

Interfaces

The default network configuration is:

Interface Name Description Default configuration
br-lan LAN & WiFi 192.168.1.1/24
eth0 LAN port None
eth1 WAN port DHCP
wlan0 WiFi Disabled

Failsafe mode

Use the instructions from → failsafe_and_factory_reset. The button to trigger failsafe during bootup is the reset button hidden between the two ethernet ports.

Buttons

hardware.button on howto use and configure the hardware button(s).

The Linksys WRT54GL has two buttons. They are Reset and Secure Easy Setup. Here, we merely name the buttons, so we can use them in the above Howto:
