4. 설정 가이드
Follow these steps to set up your U-SPEED AC1200 WiFi Router:
- 라우터 연결:
Connect the power adapter to the router's DC IN port and plug it into a power outlet. Connect one end of the included Ethernet cable to the WAN port of the router and the other end to your modem or the superior router/modem provided by your internet service provider.
- Wi-Fi에 연결:
On your computer or mobile device, search for the Wi-Fi network name (SSID) printed on the label at the bottom of your router. Connect to this network using the default Wi-Fi password also found on the label.
- 입장 Web 관리 인터페이스:
열기 web browser (e.g., Chrome, Firefox, Edge) and type the default login URL 192.168.10.1 into the address bar. Press Enter. You will be prompted to enter login credentials (usually admin/admin or as specified in the Quick Installation Guide).
- 설정 구성:
Follow the on-screen guide to configure your internet connection settings (e.g., PPPoE, Dynamic IP, Static IP) and customize your Wi-Fi network name (SSID) and password. Save your settings.
- Wi-Fi에 다시 연결:
After configuration, your router may restart. Reconnect your devices to the newly configured Wi-Fi network using your new Wi-Fi password.

5. 작동 모드
The U-SPEED AC1200 WiFi Router supports three primary operating modes to suit various network requirements:
- 라우터 모드 :
This is the default mode, where the device acts as a central hub for your network, providing internet access to all connected devices and managing network traffic. It connects to a modem and creates a new private network.
- 브리지 모드(액세스 포인트 모드):
In this mode, the router functions as an access point, extending an existing wired network wirelessly. It does not perform NAT or DHCP, relying on an upstream router for these functions. This is useful for expanding Wi-Fi coverage in a larger area.
- 리피터 모드(범위 확장 모드):
This mode allows the router to wirelessly connect to an existing Wi-Fi network and re-broadcast it, extending the range of your current Wi-Fi signal.
6. 고급 기능
6.1 듀얼 밴드 Wi-Fi
The router operates on both 2.4GHz and 5GHz frequency bands simultaneously, providing flexible and high-performance wireless connectivity.
- 2.4GHz 대역: Offers wider coverage and better penetration through walls, suitable for basic tasks like web browsing and email, with speeds up to 300 Mbps.
- 5GHz 대역: Provides faster speeds up to 867 Mbps and less interference, ideal for bandwidth-intensive activities such as 4K video streaming and online gaming.

6.2 MU-MIMO 기술
Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) technology allows the router to communicate with multiple devices simultaneously, rather than sequentially. This significantly improves network performance and efficiency, especially in environments with many connected devices, reducing latency and congestion.

6.3 빔포밍 기술
Beamforming technology intelligently focuses the Wi-Fi signal directly towards connected devices, rather than broadcasting it in all directions. This results in stronger, more reliable connections and extended Wi-Fi coverage, particularly beneficial for devices further away from the router.

6.4 Mesh Networking (EasyMesh)
The router supports EasyMesh technology, allowing it to form a seamless whole-home mesh network with other compatible devices. This eliminates Wi-Fi dead zones and ensures a consistent, strong signal as you move throughout your home, with devices automatically connecting to the strongest available node.

7. 유지관리
To ensure optimal performance and longevity of your U-SPEED AC1200 WiFi Router, consider the following maintenance tips:
- 최적의 배치: Place the router in a central location, away from obstructions, large metal objects, and interference sources (e.g., microwaves, cordless phones) to maximize Wi-Fi coverage.
- 펌웨어 업데이트: Regularly check the U-SPEED official web사이트 또는 라우터의 web management interface for firmware updates. Keeping the firmware updated ensures the latest features, security patches, and performance improvements.
- 청소: 라우터를 깨끗하고 먼지가 없는 상태로 유지하세요. 부드럽고 마른 천으로 외부를 닦으세요. 통풍구가 막히지 않도록 하세요.
- 주기적으로 재부팅: 주기적인 재부팅(예: 한 달에 한 번)은 라우터의 메모리를 정리하고 사소한 성능 문제를 해결하는 데 도움이 될 수 있습니다.
