airMAX - Guide to Configure an Indirect Wireless Point-to-Point (PtP) Link (Repeater-Style Bridge)
This article provides the instructions on how to create an indirect point-to-point link, also known as a repeated PtP link. A well-installed repeated PtP link is capable of supporting throughputs as high as 100Mbps for M devices, and 300+Mbps for AC devices.
Because this is a Layer-2 Transparent Bridge, it basically acts like a very long, invisible Ethernet cable. This article describes the steps to configure an indirect PtP link for both AC and M devices: the configuration is very similar with just small modifications that will be pointed out for each configuration.

Before you Begin
To configure and set up the indirect PtP system first follow these instructions:
- Restore your radio to factory default values. This is critical, especially if you are troubleshooting a problem.
- Connect the radio to your computer using an Ethernet cable.
- Using a web browser, enter 192.168.1.20 as the URL to gain access to the radio's management console.
- Enter ubnt as the administration account and ubnt as the password.
- You are ready to configure each radio shown in the Network Diagram above. Only change the settings that are mentioned, everything else should remain as is.

Additional Notes and Tips
1. Select the correct cable. Install all outdoor radios using UISP Cable Pro (for routine installations) or UISP Cable Carrier (when co-locating with a high-power VHF or UHF transmitter). If the Access Point will be co-located with high-power VHF transmitters, also use UISP shielded cabling. Use Ubiquiti's supplied Power over Ethernet (PoE) adapters and plug them into properly grounded AC outlets.
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.
