我购买了 HP Elitebook 725，并安装了 Ubuntu 以与 Windows 双启动。最初我安装了 14.10，但根据http://ubuntuforums.org/showthread.php?t=2254816，我安装了 14.04。在 14.04 和 14.10 上，wifi 都无法工作，以太网时断时续（我的意思是我可以 ping 通某些网站，但不能 ping 通其他网站，偶尔可以用 Firefox 连接到网站，但只能通过反复使用 Crlt-R）。
下面是我过去的无线脚本的输出http://ubuntuforums.org/showthread.php?t=370108
我对此束手无策，但还是希望 Wi-Fi 能正常工作（如果可能的话，以太网也能正常工作）。经过三天的尝试，我似乎没有取得任何进展，如果能得到任何帮助或建议，我将不胜感激。非常感谢，马丁。
