4. Operating Instructions
4.1. Connecting to a Wi-Fi Network
- Access Wi-Fi Settings: Once the driver is installed, click on the Wi-Fi icon in your computer's system tray (usually in the bottom-right corner for Windows).
- Select Network: A list of available Wi-Fi networks will appear. Select your desired network (SSID).
- Enter Password: If prompted, enter the network security key (Wi-Fi password) for your chosen network.
- Connect: Click "Connect." Your computer should now be connected to the Wi-Fi network via the ASUS USB-AC53 Nano adapter.
4.2. Dual-Band Usage
The adapter supports both 2.4 GHz and 5 GHz Wi-Fi bands. If your router broadcasts both, you may see two network names (SSIDs), often distinguished by "_2.4G" or "_5G" suffixes. For optimal performance in activities like 4K streaming or online gaming, connect to the 5 GHz band if available and within range. The 2.4 GHz band offers wider coverage and better penetration through obstacles, suitable for general use.
