Step 2: Power On the Router

Connect the provided power adapter to the router's power input port and then plug the adapter into a standard electrical outlet. The Power LED indicator should light up.

Step 3: Connect to the Internet

The router will automatically detect the 4G LTE network and establish an internet connection. The 4G/LTE LED and Internet LED should turn solid, indicating a successful connection. If you prefer a wired WAN connection, connect an Ethernet cable from your modem or wall jack to the LAN/WAN port on the router.

Operating the Router

Accessing the Web Management Interface

To configure advanced settings, open a web browser on a device connected to the router's network. Type the default access address (usually 192.168.1.1 or mwlogin.net) into the address bar and press Enter. Log in using the default username and password (often admin/admin or found on the router's label).

Wi-Fi Settings

Change SSID and Password: Navigate to the Wireless settings to customize your Wi-Fi network name and password for enhanced security.
Guest Network: Create a separate network for guests to provide internet access without sharing your main network resources.
WPS Function: Press the WPS/Reset button on the router and then the WPS button on your client device to quickly connect without entering a password.

Network Modes

The router primarily operates as a 4G LTE router. It can also function as a standard wireless router by connecting an Ethernet cable to the LAN/WAN port, allowing it to use a wired internet source instead of the 4G LTE connection.

Maintenance

Regular Firmware Updates: Check the Mercusys official website for the latest firmware updates to ensure optimal performance and security.
Cleanliness: Keep the router in a clean, dust-free environment. Avoid blocking ventilation holes.
Proper Placement: Place the router in a central location, away from obstructions and sources of interference (e.g., microwaves, cordless phones) to maximize Wi-Fi coverage.
Rebooting: Periodically reboot the router by unplugging it from the power outlet for 10 seconds and then plugging it back in. This can resolve minor network issues.

Troubleshooting

No Internet Access

Check if the 4G/LTE LED is solid. If not, ensure the SIM card is properly inserted and activated with your mobile carrier.
Verify that the Internet LED is solid. If not, check your SIM card's data plan and signal strength.
If using a wired WAN connection, ensure the Ethernet cable is securely connected and your modem is working correctly.
Try rebooting the router and your connected devices.

Weak Wi-Fi Signal

Relocate the router to a more central position in your home or office.
Avoid placing the router near large metal objects, concrete walls, or other electronic devices that may cause interference.
Ensure your devices are within the router's Wi-Fi range.

Cannot Access Web Management Interface

Ensure your device is connected to the router's network (either via Wi-Fi or Ethernet).
Verify that you are using the correct access address (e.g., 192.168.1.1 or mwlogin.net).
Clear your browser's cache and cookies, or try a different browser.
If you forgot the login password, perform a factory reset by pressing and holding the WPS/Reset button for approximately 6-8 seconds until the LEDs flash. Note that a factory reset will erase all custom settings.
