1. Select the correct cable. Use Ubiquiti ToughCable Pro shielded twisted pair data cable between your Power over Ethernet adapter and your radio. If the radio is being co-located in an area with a VHF pager, FM or TV broadcast transmitter, use Ubiquiti ToughCable Carrier cable. See our TOUGHCable Datasheet for more information.

2. Secure the radios. Modify the default administration account name and password now. From the web management console:

  • Go to System > System Accounts
  • Administrative Username [change it]
  • Hover over icon to the right, Change Password and modify it (for M devices, for AC devices simply Change Password).
  • Click the Change button. Then click the Apply button. (For M devices, for AC devices simply click the Save button)

3. Secure the wireless signal. Encrypt the wireless connection. From the web management console:

    • Go to Wireless > Wireless Security > Security > WPA2-AES
    • WPA Preshared Key: enter a strong password
    • Click the Change button. Then click the Apply button. (For M devices, for AC devices simply click the Save button)

4. In the diagram above, the block of equipment after the Switch could be replaced with anything desired to bridge, including a SOHO Wi-Fi router, for example. This radio configuration acts like a simple Cat-5 cable.
