你从哪里的文章上看到的配置文件的修改方法？你完全弄错了
/etc/modprobe.d/asus_nb_wmi.conf 里面不应该有引号
/etc/modprobe.d/iwlwifi.conf 的内容也是错的

wifi无法用是因为网卡没启用

谢谢您的回复，我的问题已经解决了，我的驱动已经装好了，只是原因是我没有开启wifi的硬件开关。

[zhidadiyu]

谢谢您的回复，我的问题已经解决了，顺便给后来的朋友和我一样遇到这个问题的朋友说下怎么解决的，实际上在安装Ubuntu的pool文件夹里就有大部分网卡驱动的安装包，之前我一直安装不上去实际上是因为自带的那个驱动已经过时，其实只用到Ubuntu官网里下载最新的bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb，这个包就可以解决大部分网卡的问题,sudo dpkg -i 安装包就可以了.如果还有朋友不明白的如果我能帮助到大家可以给我邮箱留言zhi_da_di_yu@163.com
