无线网卡找不到了

[royhu1988]

我的笔记本是ubuntu10.10 之前用ifconfig 是可以看到内置无线网卡wlan0的，也可以识别Dlink g122 识别后显示wlan11，但是我插上 TL-WN821N后识别不了，我在网上按照网友说的方法安装ath9k_htc-installer_1-0-2.deb后，安装过程没有特别提示，安装完成后不仅没有识别TL-WN821N现在连自己的内置无线网卡wlan0也找不到了插上之前可以识别的Dlink g-122之后也识别不了了，ifconfig只能找到eth0 和lo，求高手指点。现在只要能变回原来的样子就可以了。

1. sudo lshw -numeric -class network
2. sudo ifconfig -a
3. sudo route -nv

我是初学，您能说的具体一点吗，我不太看懂，就是没驱动吗？可是现在下的都是windows的驱动没有Linux的驱动啊
