4.2 Dual-Band Wi-Fi
The system operates on dual bands: 2.4GHz and 5GHz. The 2.4GHz band offers speeds up to 300Mbps, suitable for general browsing and smart home devices. The 5GHz band provides faster speeds up to 867Mbps, ideal for HD video streaming, online gaming, and large file downloads.

4.3 Seamless Roaming and Smart Connect
With Roaming/Band Steering technology, your devices automatically connect to the fastest and strongest Wi-Fi signal as you move between rooms. Smart Connect ensures a uniform Wi-Fi name (single SSID) across both bands, simplifying network management.
4.4 Gigabit LAN Ports
Each mesh unit is equipped with Gigabit Ethernet ports, allowing for high-speed wired connections to devices such as PCs, gaming consoles, or smart TVs.
4.5 MU-MIMO and Beamforming
The system supports MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) for efficient communication with multiple devices simultaneously. Beamforming (on 5GHz) focuses the Wi-Fi signal directly towards connected devices, improving signal strength and range.

5. Maintenance
To ensure optimal performance and longevity of your meross WiFi Mesh System, consider the following maintenance tips:
- Placement: Position the mesh units in open areas, away from obstructions like large metal objects, thick walls, or other electronic devices that may cause interference.
- Firmware Updates: Regularly check for and install firmware updates through the router's web interface (192.168.58.1). Updates often include performance improvements and security enhancements.
- Cleaning: Keep the units clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners.
- Restart: If you experience network issues, try restarting both mesh units by unplugging them from power for 10 seconds and then plugging them back in.
6. Troubleshooting
If you encounter issues with your meross WiFi Mesh System, refer to the following troubleshooting steps:
- No Internet Connection:
- Ensure your modem is working correctly and has an active internet connection.
- Verify that the Ethernet cable is securely connected between your modem and the first mesh router's WAN/LAN port.
- Check the LED indicator on the main mesh router. If it's not solid blue, refer to the setup instructions.
- Weak Wi-Fi Signal / Dead Zones:
- Relocate the second mesh unit closer to the area with a weak signal, ensuring it's still within good range of the first unit.
- Avoid placing units near large metal objects, microwave ovens, or cordless phones that can cause interference.
- Ensure both mesh units are powered on and their LEDs are solid blue.
- Cannot Access Router Configuration Page (192.168.58.1):
- Ensure your device is connected to the meross Wi-Fi network or directly to a mesh unit via Ethernet.
- Try clearing your browser's cache or using a different browser.
- Restart the mesh router and your device.
- Slow Speeds:
- Confirm your internet service provider (ISP) speed.
- Ensure your devices are connecting to the 5GHz band when possible for higher speeds.
- Reduce the number of active devices or bandwidth-intensive activities on your network.
