我正在使用 Dell XPS L702x 并且使用 Ubuntu 10.04,因为我需要使用 f77(不要问)并且我无法让它在更高版本的 ubuntu 上运行。
我根本无法使用 wifi。我尝试修复它,但收效甚微(将 rfkill list all 的输出从 Hard blocked: yes 更改为 hard blocked: no)。
以下是 rfkill list all 的输出
aodhan@aodhan-laptop:~$ rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
以下是 iwconfig 的输出:
aodhan@aodhan-laptop:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
pan0 no wireless extensions.
以下是 ifconfig -a 的输出:
aodhan@aodhan-laptop:~$ ifconfig -a

请帮我!
先感谢您。
编辑:
更多信息 - 这是双安装,另一个选项是 Windows 7 系统。但是,直到明天我才能访问它(直到那时我才能访问 Windows 7 光盘,而且 grub 不允许我加载它)。因此,我不能确定它是否仍然能在那里工作。不过,以前是可以的。

看来解决你的问题的方法是将内核更新到 2.6.38
引自伦敦从这有关该问题的论坛帖子
我可以确认安装 2.6.38 内核后,wifi 可以正常工作。
我有一台 Dell XPS 17 702x,装有 Ubuntu 10.04(Lucid Lynx)
你帮了我很多忙,谢谢
为此,您需要添加苯甲酸并从中更新内核
打开终端并输入此命令
sudo add-apt-repository ppa:kernel-ppa/ppa
然后更新..
sudo apt-get update
最后安装内核和头文件..
sudo apt-get install linux-headers-2.6.38-1-generic linux-image-2.6.38-1-generic
希望这能让你 Wi-Fi 恢复正常
