Setup

1. Physical Connection

1. Positioning the Router: Place the router in a central location to maximize wireless coverage. Avoid placing it near large metal objects, concrete walls, or devices that emit radio frequency interference (e.g., microwave ovens, cordless phones).
2. Connect the Antennas: Ensure both external antennas are securely attached and oriented vertically for optimal signal.
3. Connect to Power: Plug the power adapter into the router's power port and then into a wall outlet. Verify that the power LED on the router illuminates.
4. Connect to Modem: Connect one end of the provided Ethernet cable to the Internet (WAN) port on the router and the other end to your modem's Ethernet port.
5. Connect to Computer (Optional for Setup): For initial setup, you can connect your computer directly to one of the router's LAN ports using an Ethernet cable. Alternatively, you can connect wirelessly using the default Wi-Fi credentials found on the router's label.

2. Initial Configuration

1. Access Router Interface: Open a web browser on a connected computer and type http://dlinkrouter.local or 192.168.0.1 into the address bar. Press Enter.
2. Login: When prompted, enter the default username (usually admin) and password (often blank or admin). Refer to the label on the bottom of your router for exact default credentials.
3. Run Setup Wizard: Follow the on-screen instructions of the D-Link Setup Wizard to configure your Internet connection and wireless network settings.
4. Change Default Password: For security, it is highly recommended to change the default administrator password for the router's web interface.
5. Configure Wireless Network:
   • SSID (Network Name): Change the default Wi-Fi network names (SSIDs) for both 2.4 GHz and 5 GHz bands to something unique.
   • Security Mode: Select WPA2-PSK (AES) for the strongest security.
   • Pre-Shared Key (Password): Create a strong, unique password for your Wi-Fi networks.
6. Guest Network (Optional): The DIR-816L supports a guest Wi-Fi network. This allows visitors to access the internet without gaining access to your main network resources. Configure a separate SSID and password for the guest network if desired.

Operating Instructions

Connecting Devices

• Wired Devices: Connect devices such as desktop computers, gaming consoles, or network printers to the router's yellow LAN ports using Ethernet cables.
• Wireless Devices: On your wireless device (smartphone, tablet, laptop), search for available Wi-Fi networks. Select the SSID you configured during setup (e.g., "MyHomeWiFi_2.4GHz" or "MyHomeWiFi_5GHz") and enter the corresponding Wi-Fi password.

Dual Band Operation

The DIR-816L operates on two frequency bands: 2.4 GHz and 5 GHz.

• 2.4 GHz Band: Offers wider coverage and better penetration through walls, suitable for general internet browsing, email, and devices further from the router.
• 5 GHz Band: Provides faster speeds and less interference, ideal for bandwidth-intensive activities like online gaming and HD video streaming, especially for devices closer to the router.

You can connect different devices to different bands based on their needs and proximity to the router.

Cloud Features (mydlink Cloud)

The DIR-816L is a Cloud Router, meaning it can be managed remotely via the mydlink Cloud service. To utilize this feature:

1. Download the mydlink Lite app from your device's app store or visit the mydlink website.
2. Create a mydlink account and register your router using the instructions provided within the app or on the website.
3. Once registered, you can monitor and manage your network from anywhere with an internet connection.

Maintenance

• Regular Reboots: Periodically restarting your router (power cycling) can help clear its memory and resolve minor performance issues. Unplug the power adapter, wait 10 seconds, then plug it back in.
• Firmware Updates: Check the D-Link support website for firmware updates for your DIR-816L model. Firmware updates often include performance improvements, security patches, and new features. Follow the instructions provided by D-Link carefully when performing updates.
• Physical Cleaning: Keep the router free from dust and obstructions to ensure proper ventilation. Use a soft, dry cloth for cleaning.
• Secure Passwords: Regularly review and update your Wi-Fi and router administration passwords to strong, unique combinations.

Troubleshooting

No Internet Connection

• Check Cables: Ensure all Ethernet cables are securely connected to the router and modem.
• Modem Status: Verify that your modem is working correctly and has an active internet connection. Power cycle your modem if necessary.
• Router Reboot: Power cycle your D-Link router.
• ISP Connection: Contact your Internet Service Provider (ISP) to confirm there are no service outages in your area.
• Router Settings: Access the router's web interface and check the Internet connection status. Ensure your WAN settings are correctly configured (e.g., DHCP, Static IP, PPPoE).

Slow Wireless Speed or Frequent Disconnections

• Router Placement: Move the router to a more central location, away from obstructions and interference sources.
• Channel Interference: In the router's wireless settings, try changing the Wi-Fi channel for both 2.4 GHz and 5 GHz bands. Use a Wi-Fi analyzer app to identify less congested channels.
• Band Selection: Connect devices closer to the router to the 5 GHz band for better performance.
• Firmware Update: Ensure your router's firmware is up to date.
• Device Compatibility: Verify that your wireless devices support 802.11ac for optimal performance on the 5 GHz band.

Cannot Access Router's Web Interface

• IP Address: Ensure you are using the correct IP address (192.168.0.1) or hostname (dlinkrouter.local).
• Wired Connection: Try connecting your computer directly to the router via an Ethernet cable.
• Browser Cache: Clear your web browser's cache and cookies, or try a different browser.
• Firewall/Antivirus: Temporarily disable any firewall or antivirus software on your computer that might be blocking access.
• Factory Reset: As a last resort, perform a factory reset. Locate the reset button (usually a small pinhole) on the router, press and hold it for 10 seconds with a paperclip while the router is powered on. This will revert all settings to factory defaults, requiring re-configuration.
