  2. Select Network: A list of available wireless networks will appear. Identify your desired network (SSID). The Tenda U9 supports both 2.4GHz and 5GHz bands, so you may see two networks from the same router (e.g., "MyWiFi" and "MyWiFi_5G"). Choose the appropriate network.

    • Check for other devices on your network that might be consuming bandwidth.
