Tôi đang sử dụng máy tính xách tay Asus U56E và sau khi cài đặt Ubuntu 12.10 cùng với Windows 8, tôi không thể kết nối với Mạng không dây. Tôi đã cố gắng giải quyết vấn đề này từ hai tuần và không thể giải quyết nó. Xin vui lòng giúp đỡ. Bất kỳ câu trả lời sẽ được đánh giá cao.
Dưới đây là một số kết quả dòng lệnh.
