ฉันเพิ่งติดตั้ง UBUNTU 14.04 LTS บน Toshiba Satellite C655D Wifi ของฉันลดลงเป็นครั้งคราวและสิ่งที่ฉันต้องทำเพื่อเชื่อมต่อคือปิดใช้งาน wifi ของฉันและเปิดใช้งาน wifi จากไอคอนไร้สายที่มุมขวาบน มันน่ารำคาญเพียง
ความช่วยเหลือใด ๆ ที่จะได้รับการชื่นชมฉันใหม่กับ UBUNTU แต่สนใจที่จะเรียนรู้คำสั่ง linux โชคดีที่บางคำสั่งนั้นคล้ายกับ DOS และรหัสชุดงาน
ฉันใช้เราเตอร์และไม่มีปัญหากับอุปกรณ์ไร้สายอื่น ๆ ในขณะนี้รวมถึงแล็ปท็อปเครื่องอื่นที่ใช้ 14.04 แต่เป็น Aspire One รุ่นเก่า
นี่คือข้อมูลจาก wireless_script ที่ฉันพบในฟอรัม:
