2. Setup Guide

2.1 Physical Connections

1. **Insert SIM Card:** Locate the SIM card slot on the router. Carefully insert a Nano SIM card in the correct direction until it clicks into place.



2. **Connect Power:** Connect the provided USB Type-C cable to the router's power port and then to the power adapter. Plug the power adapter into a wall outlet. The router will power on automatically.
3. **Optional LAN Connection:** If you wish to connect a device via a wired connection, use the provided Ethernet cable to connect the device to the LAN port on the router.

2.2 Initial Configuration (APN Settings)

To ensure proper internet connectivity, you may need to configure the Access Point Name (APN) settings. This is typically done via the router's web interface.

1. **Connect to Router:** Connect your computer or mobile device to the router's Wi-Fi network (SSID and password usually found on a sticker on the router) or via an Ethernet cable.
2. **Access Web Interface:** Open a web browser and enter the default IP address: 192.168.1.1.
3. **Login:** Enter the default username (usually admin) and password (check the router's sticker or manual for default credentials).
4. **Navigate to APN Settings:** Once logged in, navigate to the "APN Setting" section.
5. **Configure APN:** Select "APN Profile" and enter the correct APN details provided by your mobile network operator. Ensure "4G Only" is selected for the preferred network type if you intend to use 4G exclusively.
6. **Save and Restart:** Save the settings. It is recommended to restart the router after making APN changes for them to take effect. You can usually find a "Reboot" option under "System Manage" -> "System Operate".

3. Operating Instructions

3.1 Modes of Operation

The R8 router supports two primary modes of operation:

• **Wired Mode:** Connect a network cable that can access the internet to the router's WAN/LAN port. The router will then simultaneously transmit WiFi and cable signals.
• **Wireless Mode (4G LTE):** Insert a traffic SIM card into the SIM card slot. The router will convert the 4G network signal into both wired (via LAN port) and wireless (WiFi) signals.

3.2 Connecting Devices

• **Wi-Fi Connection:** Search for the router's Wi-Fi network name (SSID) on your device and enter the Wi-Fi password.
• **LAN Connection:** Connect an Ethernet cable from the router's LAN port to your device's Ethernet port.

4. Maintenance

• **Cleaning:** Use a soft, dry cloth to clean the router. Do not use liquid cleaners or aerosols.
• **Placement:** Place the router in a well-ventilated area, away from direct sunlight, heat sources, and strong electromagnetic fields.
• **Firmware Upgrade:** Periodically check the router's web interface for available firmware updates. Keeping the firmware updated ensures optimal performance and security. (Refer to the "Firmware Upgrade" section in the web interface).
• **Resetting the Device:** If you encounter persistent issues, you can perform a factory reset. Locate the "reset" button (often a small pinhole) on the router, press and hold it for about 10 seconds while the router is powered on, then release. This will restore the router to its default factory settings.

5. Troubleshooting

Common Issues and Solutions:

• **No Internet Connection:**
  • Ensure the SIM card is correctly inserted and has an active data plan.
  • Verify APN settings are correct in the router's web interface (refer to Section 2.2).
  • Check the signal strength indicator on the router or in the web interface.
  • Restart the router and your connected devices.
• **Slow Network Speed / Signal Instability:**
  • Relocate the router to an area with better 4G signal reception.
  • Ensure the router's antennas are properly oriented.
  • Minimize interference from other electronic devices.
  • Check for network congestion with your service provider.
• **Cannot Access Router Web Interface:**
  • Ensure your device is connected to the router's network.
  • Verify you are using the correct IP address (192.168.1.1).
