How to Connect a Modem for WDSL Internet

(Technical Guide for CPE-Based Systems)

FixNet's WDSL internet service is delivered wirelessly to your home via a rooftop CPE antenna.
 For stable operation, the cabling between the rooftop device and your indoor modem/router must be connected properly.

Below are the steps for standard WDSL wiring.

System Overview

1. An Ethernet cable (RJ45) runs from the CPE antenna on the roof to inside the home.
2. The cable connects to a PoE (Power over Ethernet) adapter.
3. The PoE device sends both data and power through the same cable to the rooftop CPE.
4. Another Ethernet cable runs from the PoE device to the modem/router to enable internet access.

Types of PoE Connections

1. Two-Way PoE Split Cable (Most common setup)

In this type:

• The port labeled “DATA/POWER” receives the Ethernet cable from the rooftop.
• A 24V PoE power adapter is connected to the same port to supply electricity.
• The remaining Ethernet jack (usually unlabeled) connects to one of the yellow LAN ports on the modem/router.

Note: Do not connect this cable to the blue WAN port. It is not used in WDSL systems.

2. Integrated Plug-In PoE Adapter

This model is a single unit with two ports:

• “POE” or “DATA+POWER” → connects to the cable from the rooftop CPE.
• “LAN” → connects to the modem/router’s LAN port using a standard Ethernet cable.

Important Notes

• The blue WAN port should not be used. WDSL connections go through a LAN port.
• The PoE adapter must provide 24V. Lower voltages may prevent operation or damage the device.
• Ethernet cables must not have damaged connectors or broken clips.
• After setup, the modem should establish a connection within a few minutes.
