💡 If your Windows 7 is not updated to Service Pack 1 (SP1), the adapter may struggle to maintain a connection. Always ensure your OS is fully updated for the best wireless performance. If you'd like, I can help you further if you tell me: Do you see a specific error code (like Code 10 or Code 43)? Is your Windows 7 version 32-bit or 64-bit ? Does the adapter light up when you plug it in?
