Tôi vừa cài đặt UBUNTU 14.04 LTS trên Toshiba C655D. Wifi của tôi thỉnh thoảng bị tắt và tất cả những gì tôi phải làm để kết nối lại là vô hiệu hóa wifi của tôi và bật wifi từ biểu tượng không dây ở trên cùng bên phải. Nó chỉ gây phiền nhiễu.
Bất kỳ trợ giúp sẽ được đánh giá cao, tôi mới biết về UBUNTU, nhưng thích tìm hiểu các lệnh linux. May mắn thay, một số lệnh tương tự như DOS và mã hàng loạt.
Tôi sử dụng bộ định tuyến và không có vấn đề gì với các thiết bị không dây khác vào lúc này, kể cả một máy tính xách tay khác chạy 14.04, nhưng đó là Aspire One cũ hơn.
Đây là thông tin từ Wireless_script mà tôi tìm thấy trên diễn đàn:
