GWN76xx Master/Slave Architecture Guide
INTRODUCTION
The GWN76xx Wireless Access Points Series can be deployed in a network environment as standalone
(using only one GWN76xx to provide wireless network access) or in Master/Slave architecture (using
multiple GWN76xx units) to extend wireless network access range.
In Master/Slave configuration, a unique/chosen GWN76xx acts as master/controller and can manage (up
to 50 when using GWN7610 as Master and up to 30 when using GWN7600 as Master) other GWN76xx
series considered as slaves. Note that master GWN7600 can act as controller and can also be member of
network group(s).
This guide covers Master/Slave architecture mode giving steps to successfully configure GWN76xx access
points in your network environment; including steps to discover and pair GWN76xx units, create and
manage network groups and SSIDs.
The figure below shows a sample setup of a GWN7610 master with different slave units, and connected
Wi-Fi clients through different SSIDs defined in network groups.

DISCOVER AND PAIR GWN76XX ACCESS POINTS
In this guide, we will consider an environment where different GWN76xx access points models are installed,
one of them will be Master over the remaining ones (Slaves) as shown in Figure 1.
To set a GWN76xx as Master, we need to access to its web interface by discovering it first on the network.
The following chapter describes two methods how to discover a GWN76xx connected to network and
configure it as Master.
Discover GWN76xx
Once the GWN76xx is powered up and connected to the network correctly, it can discovered using one of
the following methods:
Method 1: Discover GWN76xx using its MAC address
1. Locate the MAC address on the MAC tag of the unit, which is on the underside of the device, or on the
package.
2. From a computer connected to same network as the GWN76xx, type in the following address
https://gwn_[MAC_address].local/ using the GWN76xx’s MAC address on your browser.
For example, if a GWN7610 has the MAC address 00:0B:82:8B:4E:28, this unit can be accessed by
typing https://gwn_000b828b4e28.local/ on the browser.

Method 2: Discover GWN76xx using GWN Discovery Tool
1. Download and install GWN Discovery Tool from the following link:
http://www.grandstream.com/sites/default/files/Resources/GWNDiscoveryTool.zip
2. Open the “GWN Discovery Tool”, click on Select to define the network interface, then click on Scan.
3. The tool will discover all GWN76xx Access Points models connected on the network showing their
MAC, IP addresses and firmware version.
4. Click on Manage Device to be redirected directly to the GWN76xx's configuration interface, or type in
manually the displayed IP address on your browser.

Notes:
At first boot or after factory reset, users will be asked to change the default administrator and user
passwords before accessing GWN76xx web interface. The new password fields are case sensitive
with a maximum length of 32 characters. Using strong passwords including letters, digits and
special characters are recommended for better security.
At factory reset, “Set unit as Master” will be checked by default, click on “Sign In” after typing the
admin’s username and password as shown above.
