นี่เป็นปัญหาใน 13.04 และมันมีปัญหากับ wifi Ubuntu จะไม่เชื่อมต่อกับเครือข่าย อุปกรณ์อื่น ๆ ของฉันทำงานได้ดี
คอมพิวเตอร์ตรวจพบเครือข่ายและเปิดกล่องโต้ตอบรหัสผ่าน wifi ฉันป้อนรหัสผ่านที่ถูกต้องคลิกตกลงและพยายามเชื่อมต่อสองสามวินาทีแล้วถามรหัสผ่านอีกครั้ง ฉันใช้อะแดปเตอร์ D-Link Wireless N 150 Pico USB ใหม่ซึ่งทำงานได้ดีภายใต้ windows เพื่อเชื่อมต่อกับเครือข่ายเดียวกัน
ฉันค้นหา Google สักสองสามชั่วโมงและไม่พบคำตอบบางทีอาจมีบางคนที่นี่ช่วยได้บ้าง

ฉันมีปัญหาที่คล้ายกันใน Ubuntu 13.10 ของฉันกับแล็ปท็อป DELL ที่แตกต่างกันสองตัวอันหนึ่งคือ Inspiron N4010 และอีกอันคือ Latitude D630 ฉันทราบว่าปัญหานั้นเหมือนกันในแล็ปท็อปทั้งสอง แต่ปัญหาเกี่ยวกับการเชื่อมต่อ WiFi กับเครือข่ายทั้งสองนั้น <br/> แล็ปท็อปของฉันไม่มีปัญหากับเครือข่ายไร้สายก่อนอัพเกรดเป็น 13.10 มีทางออกสุดท้ายสำหรับปัญหา WiFi ทั้งหมดของ Ubuntu 13.10 หรือไม่
