4. Setup Instructions

4.1 Initial Hardware Connection

1. Positioning the Router: Place the DWR-116 in a central location to maximize wireless coverage. Avoid placing it near obstructions, metal objects, or devices that emit radio frequency noise (e.g., microwave ovens).
2. Connect Power: Plug the provided power adapter into the router's power input port and then into a wall outlet. The Power LED on the front panel should illuminate.
3. Connect to Internet Source:
   • For Mobile Broadband (3G/4G LTE): Insert your compatible 3G/4G USB adapter into the USB port on the rear of the DWR-116 router.
   • For Wired Internet (DSL/Cable Modem): Connect an Ethernet cable from your DSL/Cable modem's LAN port to the blue WAN port on the DWR-116 router.
4. Connect Local Devices (Optional): For wired connections, connect Ethernet cables from your computers or other network devices to the yellow LAN ports on the DWR-116 router.

4.2 Configuration via Web Interface

1. Connect to the Router:
   • Wired: Ensure your computer is connected to one of the router's LAN ports.
   • Wireless: Connect to the router's default Wi-Fi network. The default Wi-Fi name (SSID) and password are usually printed on a label on the bottom of the router.
2. Access Web Interface: Open a web browser (e.g., Chrome, Firefox) and type the router's default IP address (commonly 192.168.0.1 or 192.168.1.1) into the address bar, then press Enter.
3. Login: Enter the default username and password. These are typically admin for both, or found on the router's label.
4. Run Setup Wizard: Follow the on-screen instructions of the setup wizard to configure your internet connection (3G/4G or WAN), Wi-Fi network name (SSID), and password. It is highly recommended to change the default administrator password for security.
5. Update Firmware: After initial setup, navigate to the firmware update section in the router's web interface and check for the latest firmware version. Updating the firmware can improve performance and security.

5. Operating the Router

5.1 Connecting to the Wireless Network

To connect a wireless device (laptop, smartphone, tablet) to your DWR-116 router:

1. On your device, enable Wi-Fi and scan for available networks.
2. Select your router's Wi-Fi network name (SSID) from the list.
3. Enter the Wi-Fi password (WPA/WPA2 key) you configured during setup.
4. Your device should now be connected to the internet.

5.2 Using WPS (Wi-Fi Protected Setup)

WPS allows for easy and secure connection of new devices without manually entering the Wi-Fi password.

1. On your wireless device, initiate the WPS connection process (often found in Wi-Fi settings).
2. Within two minutes, press the WPS button on your DWR-116 router (refer to the hardware overview for location).
3. The devices will automatically establish a secure connection.

5.3 WAN Failover Functionality

The DWR-116 features an auto-failover mechanism to ensure continuous internet connectivity.

• If you have both a wired WAN connection (DSL/Cable modem) and a 3G/4G USB adapter connected, the router can be configured to use one as the primary connection and the other as a backup.
• In case the primary WAN link is lost, the router will automatically switch to the backup 3G/4G network.
• This feature can be configured in the router's web interface under WAN settings.

6. Maintenance

• Firmware Updates: Regularly check the D-Link support website for firmware updates for your DWR-116 router. Firmware updates can provide new features, improve performance, and enhance security.
• Router Placement: Ensure the router is placed in an open area, away from walls, large metal objects, and other electronic devices that may cause interference. Optimal placement improves Wi-Fi signal strength and coverage.
• Cleaning: Keep the router clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners.
• Restarting: If you experience network issues, a simple restart of the router (unplugging the power for 10 seconds and plugging it back in) can often resolve temporary problems.
• Password Management: Periodically change your Wi-Fi password and router administration password to maintain network security.

7. Troubleshooting

This section addresses common issues you might encounter with your DWR-116 router.

• No Internet Connection:
  • Check all cable connections (power, WAN, LAN, USB adapter).
  • Verify that your internet service (3G/4G or wired) is active and working.
  • Restart your modem (if applicable) and then your router.
  • Ensure the correct WAN settings are configured in the router's web interface.
• Poor Wi-Fi Signal or Speed:
  • Relocate the router to a more central position, away from obstructions and interference sources.
