無線網路連線：

• Within two minutes, activate WPS on your device. The device will automatically connect to the Wi-Fi network without needing to enter the password.

• Log in using the administrator username and password (also on the Credential Label).

維護

Wi-Fi速度慢：

• Ensure your device is connected to the 5 GHz band if available and within close range.
