Configuring NP731 in WDS mode

1 of 18

NP731 system overview

Designed to meet the needs of today’s most demanding wireless LAN deployments, the NP731 offers a solution to create a

reliable and scalable wireless network.

The NP731 is an outdoor device that will operate in access point, repeater and WDS bridge mode. Its rugged IP68-rated metal

housing is weather proof, pressure balancing, water-tight and rust-resistant, making it an ideal solution for deployments in

harsh conditions, such as outdoor or industrial environments.

With its multi-mode set up, the device can be used in many cases to increase and enhance wireless coverage.

The NP731 has four modes of operation:

Repeater mode (default) –the NP731 repeats the wireless signal of your existing network to provide an increased

area of coverage for your premises.

Access Point mode –the NP731 connects to an existing router via Ethernet and provides a wireless signal for wireless

devices. This is useful in situations where there is no existing wireless access point or where you wish to provide a

wireless signal to a remote area from where the router is located.

CPE (Customer Premises Equipment) mode –the NP731 connects wirelessly to a remote network and provides access

to that network to clients connected via Ethernet. Use of a switch is required for multiple clients.

WDS (Wireless Distribution System) mode –the NP731 connects to up to eight (8) other NP731 units to create a

wireless mesh network. This is like repeater mode but in WDS mode, the NP731 uses a single MAC address to provide

seamless roaming.

Purpose of the document

This document provides an in-depth explanation of how to set up multiple NP731 devices in the WDS (Wireless Distribution

System) mode, the fourth mode described in the above overview.

Configuring NP731s for WDS mode

WDS mode

One NP731 connects to an existing router via Ethernet and provides a wireless signal for wireless devices. All other NP731

devices repeat the wireless signals of your existing network to provide coverage to a greater area of your premises. The

NP731 can connect with up to eight (8) other NP731 devices to create a wireless mesh network.

Example used in this Guide

In this guide, we will first configure the NP731 device connected as an access point (AP) to the Router, and then we will

configure the other four NP731 devices on the WDS system.

In the example used in this guide, the main router’s network address is: 192.168.20.0 mask 255.255.255.0

Settings not mentioned

If settings are not specifically mentioned in this document, it is assumed that the factory default settings will be used.

Technical Support Guide

1. Configure AP device Network settings

The first NP731 is connected directly with the router as the Access Point (AP).

The router will be the only device that is ‘seen’from the Internet, the AP or Repeater devices will ‘use’an IP Address which

falls in the router’s network address range.

1Navigate to System > Network Interface:

aMake the following Network settings only in the AP device:

Item

Setting

Notes

Mode

Static

Use same setting for AP and all Repeaters.

IP Address

192.168.20.254

Enter the same network address range as the main

router (192.168.20.0/24).

Netmask

255.255.255.0

Default Gateway

192.168.20.1

IP address of the main router.

Primary DNS Server

192.168.20.1

IP address of the main router.

2Click the SAVE button.

3Restart the device.

2. Configure Repeater devices Network settings (optional)

Strictly speaking, this configuration is not required. The default network settings on the Repeaters will work, but each

Repeater will be on a different network.

We suggest including all devices on the same LAN network, so that any client connected to the LAN can access both the AP

and all the Repeaters in the WDS.

1For each repeater, navigate to its System > Network Interface:

aMake the following Network settings on each numbered Repeater device:

Item

Static

Use same setting for AP and all Repeaters.

IP Address for

Repeater device 2

The AP is set to 192.168.20.254.

IP Address for

Repeater device 3
