4. 설정
Follow these steps to set up your Mercusys MB113-4G router.
4.1 SIM 카드 설치
Before powering on the router, insert your Nano SIM card.
- 라우터의 전원이 꺼져 있는지 확인하십시오.
- Locate the Nano SIM card slot on the rear panel.
- Insert the Nano SIM card into the slot until it clicks into place. Ensure the card is oriented correctly as shown in the diagram.

Figure 4.1: Inserting the Nano SIM Card
Important: Many SIM cards come with a PIN lock enabled by default. Before inserting the SIM into the router, it is highly recommended to insert it into a mobile phone and disable the PIN lock. The router's initial setup process may not prompt for the PIN, leading to connectivity issues if the SIM is locked.
4.2 전원 켜기
라우터를 전원에 연결합니다.
- Connect the included power adapter to the router's Power port and then to a wall outlet.
- Alternatively, for portable use, connect a compatible USB-C power bank to the USB-C port. Ensure the power bank provides 5V.

6. Placement and Signal Optimization
Optimal placement of the router can significantly impact signal strength and network performance.
- 위치: Place the router in a central location within the area where you need Wi-Fi coverage.
- Proximity to Windows: For optimal 4G LTE signal reception, position the router as close as possible to an exterior window. While the signal strength LEDs provide an indication, actual performance can vary significantly based on external placement.
- 장애물: 라우터를 큰 금속 물체, 콘크리트 벽 또는 간섭을 일으킬 수 있는 다른 전자 기기 근처에 두지 마십시오.

7. 유지관리
Regular maintenance helps ensure the router operates efficiently.
7.1 펌웨어 업데이트
Periodically check for and install firmware updates to improve performance, add new features, and enhance security. This can typically be done through the web management interface under System Tools or Firmware Upgrade.
7.2 청소
라우터를 깨끗하고 먼지가 없는 상태로 유지하세요. 부드럽고 마른 천으로 외부를 닦으세요. 액체 세척제나 에어로졸은 사용하지 마세요.
7.3 Wi-Fi Deactivation
If you wish to deactivate the Wi-Fi signal, note that there is no dedicated physical button for this function. You must disable Wi-Fi through the router's web management interface or the Mercusys app. If you disable Wi-Fi via the app while connected wirelessly, you will lose connection and need to use a wired connection (Ethernet) to re-enable it.
8. 문제 해결
이 섹션에서는 일반적으로 발생할 수 있는 문제에 대해 설명합니다.
8.1 인터넷 연결 없음
- SIM 카드 확인: Ensure the Nano SIM card is correctly inserted and that its PIN lock has been disabled.
- 신호 강도: Verify the 4G LTE signal strength LEDs. If the signal is weak, try repositioning the router, ideally near a window.
- APN 설정: 라우터에서 web interface or app, check the APN (Access Point Name) settings. These are usually configured automatically, but manual adjustment might be needed for some carriers.
- 데이터 요금제: Confirm that your SIM card has an active data plan and has not exceeded its data limit.
8.2 Slow Internet Speeds
- 신호 강도: A weak 4G LTE signal will result in slower speeds. Optimize router placement.
- 네트워크 혼잡: During peak hours or in congested areas, 4G LTE speeds may naturally decrease.
- Wi-Fi 간섭: Ensure your Wi-Fi channel is not congested. Use the router's settings to select a less crowded channel.
- Data Throttling: Some mobile operators may reduce speeds after a certain amount of data consumption, even on 'unlimited' plans.
8.3 Wi-Fi 연결 문제
- Wi-Fi 사용: Ensure Wi-Fi is enabled on the router (check the Wi-Fi LED). If not, enable it via the web 인터페이스 또는 앱.
- 올바른 비밀번호: 올바른 Wi-Fi 비밀번호를 입력했는지 다시 한번 확인하세요.
- 거리: Move closer to the router to rule out range issues.
- 기기 제한: The router supports up to 32 devices. Ensure you are not exceeding this limit.
