- Driver installation: Ensure Bluetooth drivers are installed. Check Device Manager for Bluetooth devices and update or reinstall drivers if needed.
- Windows Bluetooth settings: Verify Bluetooth is enabled in Windows settings (Settings > Devices > Bluetooth & other devices).
Slow Speeds or Frequent Disconnections
- Antenna position: Adjust antenna orientation for better signal reception. Try different angles.
- Interference: Move the computer away from other electronic devices (e.g., microwaves, cordless phones) that may cause wireless interference.
- Driver update: Ensure you have the latest drivers from the manufacturer's website.
- Router settings: Check your router's settings for optimal channel selection and ensure its firmware is up to date.
- Signal strength: Use Windows Wi-Fi settings to check signal strength. If very low, consider repositioning the computer or router closer to each other.
