USB 3.0 Port Usage
The integrated USB 3.0 port (5Gbps) allows you to connect external storage devices (like USB drives) to the router. This enables you to share files and media across your network, creating a simple network-attached storage (NAS) solution. USB 3.0 offers significantly faster data transmission speeds compared to USB 2.0.

WPS (Wi-Fi Protected Setup)
The WPS button on the router allows for easy and secure connection of WPS-compatible devices to your Wi-Fi network without manually entering the password. Press the WPS button on the router, then activate WPS on your device within two minutes.
Turbo Button
The Turbo button (if present and active) can be pressed to optimize network performance, potentially boosting signal strength or throughput for a short period. Refer to the web interface for specific details on its functionality.
Maintenance
- Regular Reboots: Periodically rebooting your router (unplugging the power for 10 seconds and plugging it back in) can help clear its memory and improve performance.
- Firmware Updates: Check the WAVLINK official website for firmware updates. Keeping your router's firmware up-to-date ensures optimal performance, security, and access to new features.
