我的笔记本电脑 Lenovo Ideapad Y580(购买时预装了 Windows 7 Home Premium 64 位)上的 wifi 出现问题。卸载 Win7 并安装 Ubuntu 13.10 64 位(正常有线互联网工作的地方)后,wifi 不工作!
硬件开关禁用无线。

我检查了 BIOS,那里启用了无线网卡。
Fn + F5 没有用,我的电脑在外面没有物理开关,这就是我在这里问的原因。
rfkill unblock all
仅更改软块,并向sudo ifconfig wlan0 up
我显示:SIOCSIFFLAGS: Operation not possible due to RF-kill

上述解决方案对我不起作用(HP 6910p)。我最终找到了一个 YouTube 视频,其中有人将 BIOS 设置回默认值,保存然后正常启动。我不相信这么简单的事情会奏效,但我很绝望。无论如何,它有效!我想知道为什么这个错误还没有修复......有很多文章致力于尝试解决它!

好吧,我在一台新机器上安装了 ubuntu 13.10,但搞乱了我的网络设置。
我安装了gksu
运行: sudo gksu gedit
在 gedit 中打开在 etc-network-interfaces 中找到的网络接口文件
编辑文件:
然后保存它。
只是为了确保一切正常。请检查 etc-dhcp-dhcpd.conf 中找到的 dhcpd.conf 文件以确保
选项域名“example.org”;
选项域名服务器 ns1.example.org、ns2.example.org;
默认租用时间 600;
最大租用时间 7200;
前面不要有#。
现在重新启动你的系统,我希望它能像我的一样工作
