4. Opsætning
Follow these steps to set up your Mercusys MB113-4G router.
4.1 Installation af SIM -kort
Before powering on the router, insert your Nano SIM card.

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 Tænd
Tilslut routeren til en strømkilde.
- 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.
- Beliggenhed: 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.
- Forhindringer: Undgå at placere routeren i nærheden af store metalgenstande, betonvægge eller andre elektroniske enheder, der kan forårsage interferens.

7. Vedligeholdelse
Regular maintenance helps ensure the router operates efficiently.
7.1 firmwareopdateringer
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 Rengøring
Hold routeren ren og fri for støv. Brug en blød, tør klud til at tørre ydersiden af. Brug ikke flydende rengøringsmidler eller aerosoler.
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. Fejlfinding
Dette afsnit omhandler almindelige problemer, du kan støde på.
8.1 Ingen internetforbindelse
- Tjek SIM-kort: Ensure the Nano SIM card is correctly inserted and that its PIN lock has been disabled.
- Signalstyrke: Verify the 4G LTE signal strength LEDs. If the signal is weak, try repositioning the router, ideally near a window.
- APN-indstillinger: I routerens 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.
- Dataplan: Confirm that your SIM card has an active data plan and has not exceeded its data limit.
8.2 Slow Internet Speeds
- Signalstyrke: A weak 4G LTE signal will result in slower speeds. Optimize router placement.
- Netværksoverbelastning: During peak hours or in congested areas, 4G LTE speeds may naturally decrease.
- Wi-Fi-interferens: Ensure your Wi-Fi channel is not congested. Use the router's settings to select a less crowded channel.
- Databegrænsning: Some mobile operators may reduce speeds after a certain amount of data consumption, even on 'unlimited' plans.
8.3 Problemer med Wi-Fi-forbindelse
- Wi-Fi aktiveret: Ensure Wi-Fi is enabled on the router (check the Wi-Fi LED). If not, enable it via the web brugerflade eller app.
- Korrekt adgangskode: Dobbelttjek, at du indtaster den korrekte Wi-Fi-adgangskode.
- Afstand: Flyt tættere på routeren for at udelukke problemer med rækkevidden.
- Enhedsgrænse: The router supports up to 32 devices. Ensure you are not exceeding this limit.
