Vấn đề này theo kinh nghiệm của cá nhân cháu thôi nhé. Theo cháu thấy thì xài driver ko "chính chủ" nhiều khi hiệu suất wifi không được tốt, điển hình là cũng card đó, Windows (driver chính chủ) thì bắt rất tốt còn Linux nếu driver hàng ko đc nhà sx cung cấp thì rất chập chờn. Bác có thể connect wifi bị fail nhưng bác thử lại có khi lại được, hoặc thử vài lần thì lại được.
