Overview

The GWN7662 is a Wi-Fi 6 (802.11ax) access point ideal for small-to-medium sized businesses, home offices, retail shops, restaurants and more. It offers 4x4:4 MU-MIMO technology on the 5G band and 2x2:2 MU-MIMO on the 2.4G band, as well as a sophisticated antenna design for maximum network throughput and expanded Wi-Fi coverage range. To ensure easy installation and management, the GWN7662 uses a controller-less distributed network management design in which the controller is embedded within the product's web user interface. The GWN7662 is also supported by GWN.Cloud and GWN Manager, Grandstream's free cloud and on-premise Wi-Fi management platform. It is the ideal Wi-Fi AP for voice-over-Wi-Fi deployments and offers a seamless connection with Grandstream's Wi-Fi capable IP phones. With support for advanced QoS, low-latency real-time applications, mesh networks, captive portals, 256 concurrent clients per AP, and dual Gigabit network ports with PoE/PoE+, the GWN7662 is the ideal Wi-Fi access point for medium wireless network deployments with medium user density.

Hardware Installation

The GWN7662 can be mounted on the wall or ceiling. Please refer to the following steps for the appropriate installation.

Wall Mount

Place the mounting bracket on the desired location on the wall with the arrow pointing upwards.
Use a pencil to mark the four mounting holes (screw holes DIA 5.5mm, reticle hole DIA 25mm).
Insert the screw anchors into the 5.5mm holes. Fix the mounting bracket to the wall by inserting the screws into the anchors. (Illustration showing wall, mounting bracket, screws, and plastic expansion bolt).
Connect the Ethernet cable (RJ45) to the correct ports of your GWN7662.
Align the arrow on the GWN7662 AP with the arrow on the locking tab of the mounting bracket and ensure that your GWN is firmly seated on the mounting bracket.
Turn the GWN clockwise until it locks into place and fits the locking tab. (Illustration showing connection of Ethernet cable, alignment of arrows, and turning the unit to lock).

Ceiling Mount

Note: Ceiling mounting is recommended for optimal coverage performance.

Remove the ceiling tile.
Place the ceiling backing plate in the center of the ceiling tile and mark the mounting screw holes (screw holes DIA 5.5mm, reticle hole DIA 25mm).
Insert the screws through the mounting bracket. (Illustration showing ceiling tile, backing plate, screws, and M3 nut).
Connect the Ethernet cable (RJ45) to the correct ports of your GWN7662.
Align the arrow on the GWN7662 AP with the arrow on the locking tab of the mounting bracket and ensure that your GWN is firmly seated on the mounting bracket and connect the network and power cables.
Turn the GWN clockwise until it locks into place and fits the locking tab. (Illustration showing connection of Ethernet cable, alignment of arrows, and turning the unit to lock).

Connecting to GWN7662 Default Wi-Fi Network

The GWN7662 can be used as a standalone access point out of the box, or after factory reset with Wi-Fi enabled by default. After powering the GWN7662 and connecting it to the network, the GWN7662 will broadcast a default SSID based on its MAC address GWN[MAC's last 6 digits] and a random password.

Note: GWN7662's default SSID and password information are printed on the MAC tag of the unit.

Accessing the Configuration Interface

A computer connected to the GWN7662's SSID, or to the same network as the GWN7662, can discover and access its configuration interface using one of the below methods:

Method 1: Discover GWN7662 using its MAC Address

Locate the MAC address on the MAC tag of the unit, which is on the underside of the device, or on the package.
From a computer connected to the same network as the GWN7662, type in the following address using GWN7662's MAC address on your browser: https://gwn_<mac>.local. Example: If a GWN7662 has the MAC address 00:0B:82:8C:4D:F8, this unit can be accessed by typing https://gwn_000b828c4df8.local on the browser.

Method 2: Discover GWN7662 using GWN Discovery Tool

Download and install GWN Discovery Tool from the following link: https://www.grandstream.com/tools/GWNDiscoveryTool.zip
Open the GWN Discovery Tool, and click on Scan.
The tool will discover all GWN76XX Access Points connected on the network showing their MAC and IP addresses.
Click on Manage Device to be redirected directly to the GWN7662's configuration interface, or type in manually the displayed IP address on your browser.

Enter username and password to login. (The default administrator username is “admin” and the default random password can be found at the sticker on the GWN7662).

Notes

Make sure that the GWN7662 is not already paired with another GWN76xx Access Point as slave, GWN Router Series, or GWN.Cloud, otherwise the configuration interface cannot be accessed.
If the GWN7662 is already paired, make sure to unpair it first, or do a factory reset.
It is the customer's responsibility to ensure compliance with local regulations for frequency bands, transmit power, and others.
