A diagram shows "Strong" and "Weak" signal interpretations based on the number of lit LEDs.
Method 2: WPS (Wi-Fi Protected Setup) Setup
WPS offers a quick way to connect your extender to a WPS-compatible router.
- เปิดเครื่อง: Plug the DAP-1955-US extender into an electrical outlet.
- กด WPS บนเราเตอร์: Within two minutes, press the WPS button on your existing Wi-Fi router.
- กด WPS บน Extender: Immediately after, press the WPS button on the side of your DAP-1955-US extender (refer to Figure 5).
- รอการเชื่อมต่อ: 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.
- เพิ่มประสิทธิภาพการวางตำแหน่ง: 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).
คำแนะนำการใช้งาน
Once set up, your D-Link DAP-1955-US extender operates automatically to extend your Wi-Fi network.
- ขยายพื้นที่ครอบคลุมสัญญาณ Wi-Fi: The extender broadcasts your existing Wi-Fi network, allowing devices to connect to the stronger signal provided by the extender.

- พอร์ตกิกะบิตอีเทอร์เน็ต: 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.
- เทคโนโลยี MU-MIMO: 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.
การซ่อมบำรุง
To ensure optimal performance and longevity of your D-Link DAP-1955-US extender, consider the following maintenance tips:
- อัพเดตเฟิร์มแวร์: 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.
- การทำความสะอาด: รักษาอุปกรณ์ให้สะอาดและปราศจากฝุ่น ใช้ผ้าแห้งนุ่มเช็ดทำความสะอาดภายนอก หลีกเลี่ยงการใช้น้ำยาทำความสะอาดหรือสเปรย์
- การระบายอากาศ : 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.
- การรีเซ็ต: 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.
การแก้ไขปัญหา
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.
- ลองรีสตาร์ทเราเตอร์และตัวขยายสัญญาณของคุณอีกครั้ง
- 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.
- ความเร็วต่ำหรือการเชื่อมต่อไม่เสถียร:
- 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.
- ตรวจสอบสัญญาณรบกวนจากอุปกรณ์อิเล็กทรอนิกส์อื่นๆ (เช่น ไมโครเวฟ โทรศัพท์ไร้สาย)
- ตรวจสอบให้แน่ใจว่าเฟิร์มแวร์ของเราเตอร์ของคุณเป็นเวอร์ชันล่าสุด
- 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.
- ลองถอนการติดตั้งแล้วติดตั้งแอปใหม่อีกครั้ง
- 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).
- ไม่สามารถเข้าถึง Web-based Configuration Utility:
- Ensure your computer is connected to the extender's network (either via Ethernet or its Wi-Fi).
- ลองเข้าใช้งาน 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.
