5. 사용 설명서
Once your router is set up, you can utilize its various functions:
- WiFi 연결성: The router broadcasts two separate WiFi networks (2.4 GHz and 5 GHz). Connect your devices to the appropriate network for optimal speed and range. The 5 GHz band offers faster speeds for close-range devices, while the 2.4 GHz band provides better range for devices further away.
- USB 공유: Plug a USB printer or storage device into the USB 2.0 or USB 3.0 ports on the router. You can then configure printer sharing or access files on the storage device across your network. ASUS AiCloud 2.0 allows you to access these files remotely from anywhere with an internet connection.
- ASUS Router App Management: Use the mobile app to monitor network traffic, manage connected devices, set up parental controls, and adjust various router settings without needing a computer.
- AiMesh System: If you have another compatible ASUS router, you can create an AiMesh system. This extends your WiFi coverage by using multiple ASUS routers to form a single, seamless network, eliminating dead zones. Refer to the ASUS website or the AiMesh section in the ASUSWRT interface for detailed setup instructions.

- 정기 재부팅: 몇 주에 한 번씩 공유기를 재부팅하면 메모리를 정리하고 사소한 네트워크 문제를 해결하여 안정성을 향상시킬 수 있습니다.
- 물리적 청소: 라우터를 통풍이 잘 되는 곳에 두고, 과열을 방지하기 위해 통풍구에 쌓인 먼지를 주기적으로 청소하십시오.
