我的無線WIFI操作不了

[ray_cheang2003]

因為昨天手賤把無線網咭驅動重裝,但不成功.留下旧驅動還留下.
之後我的無線網咭操作就不能工作起來,好像鎖了般.
但我在TERMINAL 中得到以下這息

是自编译安装了一遍新驱动不成功？如是，应该可以用以下方法去掉残留的错误驱动：

1. 看一下在grub里是否留有前面版本的kernel，确保grub中有2个以上版本的kernel（为防止进一步的意外，最好有3个以上的版本）；

2. 然后有用你习惯的方式卸载掉当前工作的那个kernel，用synaptic或commadn line都行；

3. 卸载当前版本的kernel成功后，reboot；

4. 重新装回刚才卸载的那个版本的kernel；

5. 用新安装的kernel重新boot，检查无线是否可用，如有必要再自行编译安装无线驱动。

Your old wireless subsystem modules were left intact:

這是我之前安裝驅動時信息

如果不是又什麼做。
而且能否詳細一點如何做。

我前面写了那么多，你好象试都没试过吧？

以我现在能够看到的信息，你的AR9285的无线网卡在ubuntu14.04的3.13.x版本的内核下是不需要额外再安装什么驱动的，系统内核中包含的kernel module ath9k就可以正常驱动了。所以等于你前面手动再安装你自己下载的驱动就是一个画蛇添足的动作。

解决的思路看我前面的那个回复。就是把你目前使用的内核先¨彻底删除¨（不知道什么是彻底删除，就安装一个synaptic，删除包的时候会给你选择的），重启系统后系统使用的就是前一个版本的内核了，这个内核是不包括你自行编译的驱动模块的，所以应该可以正常使用无线网络。确认好这一步成功了，再去把3.13.0-35的内核装回来，问题就解决了。
