3. Setup Instructions

There are two primary methods to set up your D-Link DAP-1720 Range Extender: using Wi-Fi Protected Setup (WPS) or manual configuration via a web browser.

3.1 WPS Setup (Recommended)

1. Power On: Plug the DAP-1720 into a power outlet near your existing wireless router. Wait for the power LED to turn solid green.
2. Activate WPS on Router: Press the WPS button on your wireless router. Refer to your router's manual for the exact location of this button.
3. Activate WPS on Extender: Within two minutes, press the WPS button on the DAP-1720 (often indicated by a circular arrow icon).
4. Monitor Status: The signal indicator LEDs on the DAP-1720 will flash during the connection process. Once connected, the LEDs will turn solid green, indicating a successful connection.
5. Optimal Placement: Unplug the DAP-1720 and move it to a location halfway between your router and the Wi-Fi dead zone. Plug it into a power outlet. The Smart Signal Indicator LEDs will help you find the best spot. Aim for at least two solid green bars for good signal strength.

Note: If the signal indicator shows red or only one bar, move the extender closer to your router.

3.2 Manual Setup (Web Browser)

1. Power On: Plug the DAP-1720 into a power outlet near your existing wireless router.
2. Connect to Extender: On your computer or mobile device, connect to the D-Link extender's default Wi-Fi network (e.g., "dlink-XXXX"). The default Wi-Fi name and password are usually found on a label on the device or in the Quick Installation Guide (QIG).
3. Access Setup Wizard: Open a web browser and type http://dlinkap.local or the default IP address (e.g., 192.168.0.50) into the address bar.
4. Follow On-Screen Instructions: The setup wizard will guide you through selecting your existing Wi-Fi network(s) and configuring the extender's settings, including its new Wi-Fi name and password.
5. Optimal Placement: After configuration, unplug the DAP-1720 and move it to a suitable location as described in step 5 of the WPS setup.

4. Operating Your Range Extender

4.1 Connecting Devices

• Wireless Devices: Once the extender is set up, search for the new extended Wi-Fi network name (SSID) on your devices (e.g., "YourNetworkName_EXT" or "YourNetworkName_5G_EXT") and connect using the password you configured.
• Wired Devices: For devices like smart TVs, gaming consoles, or desktop computers that benefit from a stable wired connection, use an Ethernet cable to connect them to the Gigabit Ethernet port on the DAP-1720.

4.2 Dual-Band Functionality

The DAP-1720 operates on both 2.4 GHz and 5 GHz frequency bands. The 2.4 GHz band offers wider coverage and better penetration through walls, while the 5 GHz band provides faster speeds over shorter distances with less interference. Your devices will automatically connect to the optimal band, or you can manually select the preferred band if separate SSIDs were configured during setup.

5. Maintenance

• Firmware Updates: Periodically check the D-Link support website for firmware updates. Keeping your device's firmware up-to-date ensures optimal performance, security, and access to new features.
• Cleaning: Ensure the device's ventilation slots are clear of dust to prevent overheating. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Resetting the Device: If you encounter persistent issues or wish to reconfigure the extender from scratch, you can perform a factory reset. Locate the reset button (usually a small pinhole) on the device, and while the device is powered on, press and hold it for about 10 seconds using a paperclip until the LEDs flash.

6. Troubleshooting

6.1 No Internet Access After Connecting to Extender

• Check Router Connection: Ensure your main router is working correctly and has internet access.
• Extender Placement: Verify the DAP-1720 is placed within range of your main router. The Smart Signal Indicator should show at least two green bars. Relocate if necessary.
• Re-run Setup: Try re-running the WPS or manual setup process to ensure the extender is properly connected to your main Wi-Fi network.
• IP Address Conflict: If you manually configured the extender, ensure its IP address does not conflict with other devices on your network.

6.2 Poor Signal or Slow Speeds

• Relocate Extender: Move the extender closer to your main router. The ideal location is halfway between the router and the area needing coverage.
• Minimize Interference: Keep the extender away from large metal objects, concrete walls, and devices that emit radio frequency interference (e.g., microwaves, cordless phones).
• Check Router Performance: Ensure your main router is providing adequate signal strength and speed.
• Firmware Update: Ensure the extender's firmware is up-to-date.

6.3 Cannot Access Web-Based Setup Page

• Verify Connection: Ensure your device is connected to the extender's Wi-Fi network (e.g., "dlink-XXXX") or directly via Ethernet.
• Correct Address: Double-check that you are typing http://dlinkap.local or the correct IP address into your browser's address bar.
• Clear Browser Cache: Try clearing your browser's cache and cookies, or use a different browser.
• Temporarily Disable Firewall/Antivirus: Your computer's security software might be blocking access.
• Factory Reset: If all else fails, perform a factory reset and attempt the manual setup again.
