    Ubiquiti WT5-ULB Wireless Bridge Setup

    July 14th, 2025

    This guide will walk you thorough how configure the WT5-ULB. 

    There are two configuration examples below. The first details a 1-to-1 setup with one access point and one station, this is the most common. The second setup is a 1-to-2 setup for when you have two locations (stations) to go back to a single point (access point). The same steps can be followed to add additional stations.





    Setting up 1 Access Point and 1 Station

    Before beginning, it is recommended to setup the devices first, before mounting them. A computer with a ethernet port will be required.

    Access Point Setup

    1. Connect power to the included Ubiquiti PoE Injector, and connect the Ubiquiti antenna to the PoE port. Connect the LAN port to the ethernet port on the computer. Allow 2 minutes for the device to power up.
    2. Open Google Chrome, and enter the default IP address for the device, 192.168.1.20 (If you are unable to connect to the device, ensure your computer is in the same IP address range.)
      NOTE: As of February 2025 Ubiquiti ULB devices have DHCP enabled by default - If you have a router attached to your network the Ubiquiti may not be on the 192.168.1.20 address. If this happens, login to your router to find what IP address it has give to the Ubiquiti device.
    3. You may be prompted that the connection is not private, select the proceed option.
    4. Select your Country, and Language. Tick the agreement box, and select Continue.
    5. Enter a Username and Password. Record these details in a safe place for later use. Select Save.
    6. Select Network.
    7. Change the IP address of the device to suit your network. In our example it will be static, with the address of 192.168.1.100. Select Save Changes.
    8. You will loose connection to the device, wait 1-2 minutes and enter the new IP address into your web browser. You will be required to log into the device again.
    9. Select the Wireless Settings option.
    10. Turn on Access Point and PTP Mode. Enter a SSID, this can be anything, it will be the Wi-Fi network name. Enter a WPA2 Preshared Key, this will be the password for the Wi-Fi network you are creating. Select Save Changes. Record these details in a safe place for later use.
    11. Disconnect your computer from the Ubiqutii, leaving the Ubiquiti connected to the PoE injector.

    Station Setup

    Wiring Examples

    Standalone Cameras over a pair of WT5-ULBs


    Cameras connected to an NVR over a pair of WT5-ULBs


    You can have multiple Cameras if you add them to either of the Switches. If you do so, we recommend that the Ethernet cable that runs between the Switch and the PoE Injector is plugged into the uplink or gigabit port on the Switch.


    Multiple Cameras connected to an NVR over multiple WT5-ULBs

    In this example, there are multiple stations sending data back to one access point. This is useful if you have multiple buildings in the 120 degree field of view from the access point. The same steps as above are followed for configuration.

    WiFi via an Access Point across a pair of WT5-ULBs

    Using a Switch between the AP's POE injector and the Station's PoE injector will allow you to connect multiple cameras/devices. If you do so, we recommend that the ethernet cable that runs between the Switch and the PoE Injector is plugged into the uplink or gigabit port on the Switch.
