我使用 ubuntu 16.04 LTS 我正在尝试安装 tp-link wn722n 如何在 Ubuntu 14.04 上安装 TP-Link TL-WN722N 的驱动程序？
经过上述设置后，我的默认笔记本电脑 wifi 适配器未被检测到。而且 tp-link 适配器也不起作用

我尝试这样做来恢复：
sudo apt-get install linux linux-headers-generic kernel-package
sudo apt-get purge b43-fwcutter firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl*
sudo apt-get install b43-fwcutter firmware-b43-lpphy-installer bcmwl*
sudo apt-get install b43-fwcutter firmware-b43-installer bcmwl*
和这个：
sudo apt-get remove bcmwl-kernel-source
sudo apt-get remove firmware-b43-installer b43-fwcutter
sudo apt-get install firmware-b43-installer b43-fwcutter
我不明白如何恢复我的默认 wifi 适配器笔记本电脑驱动程序。
