4. Setup Instructions
- Insert the Adapter: Plug the UGREEN AC1300 WiFi Adapter into an available USB 3.0 port on your desktop or laptop computer. For optimal performance, use a USB 3.0 port (usually blue inside).
- Driver Installation:
- Windows 10/11: The adapter features a built-in driver. In most cases, Windows will automatically detect and install the necessary drivers. Wait for the installation to complete.
- Other Windows Versions (7/8/8.1/XP), Mac OS, Linux: If the driver does not install automatically, you may need to install it manually. The driver can typically be found on the included mini-CD (if provided) or downloaded from the official UGREEN support website. Follow the on-screen instructions for installation.
- Adjust Antennas: Once the adapter is recognized and drivers are installed, adjust the dual antennas for the best signal reception. You can rotate them vertically up to 90° and laterally up to 180°. Experiment with different angles to find the strongest signal.
- Connect to WiFi: After driver installation, your computer should detect available WiFi networks. Select your desired network and enter the password to connect.

5. Operating Modes
5.1. Receive Mode (Station Mode)
In Receive Mode, the adapter acts as a standard WiFi client, allowing your computer to connect to an existing wireless network (router). This is the primary mode for most users.
- Ensure the adapter is properly installed and drivers are functioning.
- Open your computer's network settings (e.g., WiFi icon in the taskbar for Windows, Network Preferences for Mac).
- Select the desired WiFi network from the list of available networks.
- Enter the network security key (password) if prompted.
- Click 'Connect'. Your computer should now be connected to the internet wirelessly.

5.2. Launch Mode (Soft AP Mode)
In Launch Mode, the adapter can turn your computer into a wireless hotspot, allowing other devices (like smartphones or tablets) to connect to your computer's internet connection.
- Ensure your computer has an active internet connection (e.g., via Ethernet or another WiFi adapter).
- Access the adapter's utility software or your operating system's hotspot settings.
- Enable the 'Soft AP' or 'Mobile Hotspot' function.
- Configure the network name (SSID) and password for your new hotspot.
- Other devices can now search for your hotspot's SSID and connect using the password you set.

5.3. Dual-Band Usage
The adapter supports both 5GHz and 2.4GHz bands. You can choose the band that best suits your needs:
- 5GHz Band: Offers higher speeds and less interference, ideal for online gaming, 4K video streaming, and large file transfers. Best for devices closer to the router.
- 2.4GHz Band: Provides wider coverage and better penetration through walls, suitable for general internet browsing and devices further away from the router.

6. Maintenance
- Keep Clean: Regularly clean the adapter with a soft, dry cloth to prevent dust buildup, especially around the USB connector and antenna hinges.
- Avoid Physical Damage: Handle the adapter carefully. Avoid dropping it or exposing it to excessive force, which could damage the antennas or internal components.
- Optimal Placement: For best performance, ensure the adapter is not obstructed by other objects and is positioned to receive a clear signal from your router.
- Temperature and Humidity: Store and operate the adapter within recommended temperature and humidity ranges to prevent damage. Avoid extreme heat, cold, or moisture.
7. Troubleshooting
7.1. No WiFi Signal or Connection
- Check Adapter Connection: Ensure the adapter is securely plugged into a USB 3.0 port. Try a different USB port.
- Driver Installation: Verify that the drivers are correctly installed. Check Device Manager (Windows) or System Information (Mac/Linux) to see if the adapter is recognized without errors. Reinstall drivers if necessary.
- Router Status: Ensure your WiFi router is powered on and broadcasting a signal. Try restarting your router.
- Antenna Adjustment: Adjust the adapter's antennas to different positions to optimize signal reception.
- Interference: Move the adapter away from other electronic devices that might cause interference (e.g., microwaves, cordless phones).
7.2. Slow Connection Speed
- USB 3.0 Port: Ensure the adapter is connected to a USB 3.0 port for maximum speed. USB 2.0 ports will limit performance.
- Signal Strength: Check the WiFi signal strength. A weak signal can lead to slower speeds. Try moving closer to the router or adjusting antennas.
- Band Selection: For faster speeds, connect to the 5GHz band if available and within range. The 2.4GHz band offers wider coverage but generally lower speeds.
- Router Congestion: If many devices are connected to your router, it might be congested. Try disconnecting some devices or optimizing router settings.
- Driver Update: Ensure you have the latest drivers installed for the adapter.
7.3. Hotspot (Soft AP) Mode Not Working
- Internet Connection: Verify that your computer has a stable internet connection before attempting to create a hotspot.
- Software/OS Settings: Ensure the Soft AP feature is enabled and configured correctly in the adapter's utility software or your operating system's settings.
- Firewall/Antivirus: Temporarily disable your firewall or antivirus software to see if it's blocking the hotspot functionality.

8. User Tips
- For desktop users, consider using a USB extension cable to position the adapter higher or in a more open area for better signal reception.
- If experiencing intermittent connections, try manually setting your router's 5GHz channel to a less congested one (e.g., 36, 40, 44, 48).
- Always keep your operating system and adapter drivers updated for optimal performance and security.
- When using Soft AP mode, ensure your computer's power settings are configured to prevent it from going to sleep, which would disable the hotspot.
