3. Package Contents

Verify that your package contains the following items:

• Grandstream GWN7665 Wi-Fi 6E Access Point

Note: Power over Ethernet (PoE) injector or PoE-enabled switch is required for operation and is not included in the standard package.

4. Setup

4.1 Powering the Device

The GWN7665 supports Power over Ethernet (PoE/PoE+). Connect an Ethernet cable from a PoE/PoE+ enabled switch or a PoE injector to either of the Ethernet ports on the GWN7665. The device will power on automatically.

4.2 Network Connection

Connect the GWN7665 to your network infrastructure via one of the two Gigabit Ethernet ports (1G or 2.5G). For optimal performance, utilize the 2.5G port if your network supports it.

4.3 Mounting

The GWN7665 can be mounted on a wall or ceiling. Use the provided mounting bracket and hardware to secure the access point in a central location for optimal Wi-Fi coverage.

4.4 Initial Configuration

Upon first boot, the GWN7665 will broadcast a default SSID. You can connect to this SSID to access the web management interface. Alternatively, you can discover and manage the device using Grandstream's GWN Discovery Tool, GWN.Cloud, or GWN Manager.

• Embedded Controller: One GWN7665 can act as a controller for up to 50 local GWN APs, simplifying management for small to medium deployments.
• GWN.Cloud: For larger or distributed deployments, GWN.Cloud offers unlimited cloud-based AP management.
• GWN Manager: An on-premise software solution for managing GWN access points.

5. Operating Instructions

5.1 Network Configuration

Access the web management interface using a web browser. The default IP address can typically be found via the GWN Discovery Tool or by checking your DHCP server. Log in with the default credentials (usually admin/admin or found on the device label).

From the interface, you can configure:

• SSIDs: Create and manage multiple Wi-Fi networks (SSIDs) for different purposes (e.g., employee, guest).
• Security: Set up WPA2/WPA3 encryption, MAC filtering, and other security protocols.
• VLANs: Segment your network traffic for improved security and management.
• Radio Settings: Adjust channels, transmit power, and bandwidth for 2.4GHz, 5GHz, and 6GHz bands.
• QoS: Prioritize critical traffic to ensure smooth operation of latency-sensitive applications.

5.2 Wi-Fi 6E Benefits

The GWN7665 leverages Wi-Fi 6E technology, utilizing the 6GHz band for cleaner, less congested wireless communication. This results in higher speeds and lower latency for compatible devices. The Tri-Band (2.4GHz, 5GHz, 6GHz) operation, combined with MU-MIMO and OFDMA, allows for efficient communication with multiple devices simultaneously, improving overall network performance in high-density environments.

6. Maintenance

6.1 Firmware Updates

Regularly check for and apply firmware updates to ensure optimal performance, security, and access to new features. Firmware updates can typically be performed through the web management interface or via GWN.Cloud/GWN Manager.

6.2 Cleaning

Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid or aerosol cleaners.

6.3 Security Best Practices

Always change default passwords immediately after initial setup. Utilize strong, unique passwords for administrative access. Enable advanced security features like secure boot and digital signatures where applicable to protect against unauthorized access and tampering.

7. Troubleshooting

7.1 No Power

Ensure the Ethernet cable is securely connected to a PoE/PoE+ source. Verify that the PoE/PoE+ source is active and providing power.

7.2 Cannot Access Web Interface

Verify that your computer is on the same network segment as the GWN7665. Use the GWN Discovery Tool to find the device's IP address. Try clearing your browser's cache or using a different browser. If you have forgotten the password, a factory reset may be necessary (refer to the full product documentation for reset procedures).

7.3 Poor Wi-Fi Performance

Check for potential interference from other wireless devices. Adjust channel settings to less congested channels. Ensure the access point is mounted in an optimal location, free from obstructions. Verify that client devices support Wi-Fi 6E for best performance on the 6GHz band.

7.4 Limited Connectivity Outside the US

Some features, such as cloud portal access, may have regional restrictions. Consult Grandstream's official support resources for region-specific operational guidelines and limitations.
