Setup Instructions

There are two primary methods for setting up your D-Link DAP-1955-US extender: using the D-Link Wi-Fi app or via the WPS (Wi-Fi Protected Setup) button.

Method 1: D-Link Wi-Fi App Setup (Recommended)

1. Download the App: Download the free D-Link Wi-Fi app from the Apple App Store or Google Play Store on your smartphone or tablet.

3. Launch App: Open the D-Link Wi-Fi app and follow the on-screen instructions to set up your extender. The app will guide you through connecting to the extender's temporary Wi-Fi network and configuring it to extend your main router's Wi-Fi.
4. Placement Optimization: Use the Smart Signal Indicator LEDs on the front of the extender to find the optimal placement. Green LEDs indicate a strong signal from your router, while orange or red may suggest moving the extender closer to the router.

Method 2: WPS (Wi-Fi Protected Setup) Setup

WPS offers a quick way to connect your extender to a WPS-compatible router.

1. Power On: Plug the DAP-1955-US extender into an electrical outlet.
2. Press WPS on Router: Within two minutes, press the WPS button on your existing Wi-Fi router.
3. Press WPS on Extender: Immediately after, press the WPS button on the side of your DAP-1955-US extender (refer to Figure 5).
4. Wait for Connection: The extender's LEDs will flash during the connection process. Once connected, the signal indicator LEDs will light up green, indicating a successful connection and signal strength.
5. Optimize Placement: Relocate the extender to an area between your router and the Wi-Fi dead zone. Use the Smart Signal Indicator LEDs to ensure optimal signal strength (refer to Figure 5).

Operating Instructions

Once set up, your D-Link DAP-1955-US extender operates automatically to extend your Wi-Fi network.

• Extended Wi-Fi Coverage: The extender broadcasts your existing Wi-Fi network, allowing devices to connect to the stronger signal provided by the extender.

• Mesh Wi-Fi Compatibility: If you have a compatible D-Link Mesh-enabled router, the DAP-1955-US can seamlessly integrate into your mesh network, providing a unified Wi-Fi experience with smart roaming. This means your devices will automatically switch to the strongest Wi-Fi signal as you move around your home without interruption.

• Gigabit Ethernet Port: Use the Ethernet port on the bottom of the extender to connect any wired device for a stable and fast network connection. This is ideal for devices that require consistent bandwidth, such as desktop computers, gaming consoles, or smart TVs.
• MU-MIMO Technology: The extender utilizes MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) technology to ensure high speeds for multiple devices simultaneously, reducing buffering and improving overall network efficiency.

Maintenance

To ensure optimal performance and longevity of your D-Link DAP-1955-US extender, consider the following maintenance tips:

• Firmware Updates: Regularly check for and install firmware updates through the D-Link Wi-Fi app or the web-based configuration utility. Updates often include performance improvements, security patches, and new features.
• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth to wipe the exterior. Avoid using liquid cleaners or aerosols.
• Ventilation: Ensure the extender is plugged into an outlet with adequate ventilation. Do not cover the device or place it in enclosed spaces that could restrict airflow, as this can lead to overheating.
• Resetting: In case of persistent issues, a factory reset can often resolve problems. To perform a factory reset, use a paperclip to press and hold the reset button (located on the bottom, next to the LAN port) for approximately 10 seconds while the device is powered on. The device will reboot with default settings.

Troubleshooting

This section addresses common issues you might encounter with your D-Link DAP-1955-US extender.

• Extender Not Connecting / Blinking Red Light:
  • Ensure the extender is within range of your main Wi-Fi router. Move it closer if the signal indicator LEDs are red or orange.
  • Verify that your router's Wi-Fi is active and broadcasting.
  • Try restarting both your router and the extender.
  • If using WPS, ensure you press the WPS button on both the router and extender within the specified timeframe (usually 2 minutes).
  • Consider using the D-Link Wi-Fi app for setup, as it provides more guided steps and feedback.
• Slow Speeds or Intermittent Connection:
  • Relocate the extender to a more central location between your router and the devices needing extended coverage. Aim for a location where the signal indicator shows at least two or three green bars.
  • Check for interference from other electronic devices (e.g., microwaves, cordless phones).
  • Ensure your router's firmware is up to date.
  • If connecting wired devices, ensure the Ethernet cable is securely plugged into the Gigabit Ethernet port.
• D-Link Wi-Fi App Issues:
  • Ensure your smartphone's cellular data is temporarily disabled during the initial setup process to prevent conflicts.
  • Grant the app necessary local network permissions on your device.
  • Try uninstalling and reinstalling the app.
  • If the app fails, consider using the web-based configuration utility by connecting a computer directly to the extender via Ethernet or its temporary Wi-Fi network and navigating to its default IP address (often found in the quick install guide or by scanning your network for connected devices).
• Cannot Access Web-based Configuration Utility:
  • Ensure your computer is connected to the extender's network (either via Ethernet or its Wi-Fi).
  • Try accessing dlinkap.local or the extender's default IP address (e.g., 192.168.0.50). If unsure, you may need to check your router's connected devices list to find the extender's assigned IP.
  • The default password for the utility is often "password" or left blank. Refer to the quick install guide for specific credentials.
