我买了新的笔记本电脑并激活了一些设备（视频、CPU 固件）的附加驱动程序。
但在激活 wifi 适配器的自定义驱动程序后，我收到错误。现在，连接管理器中没有出现任何 wifi 设备（没有互联网），并且 wifi 卡未列在附加驱动程序设置页面上。
之后，我遇到了同样的蓝牙问题。它从附加驱动程序设置页面中消失了，但蓝牙设备仍在工作。
我如何清除额外的驱动程序设置？
我的硬件：
- Ubuntu 16.04
- 戴尔笔记本电脑
更新：
$ lspci -knn | grep Net -A3
02:00.0 Network controller [0280]: Intel Corporation Device [8086:24fd] (rev 78)
Subsystem: Intel Corporation Device [8086:0050]
我已经停用安全启动，但没有任何变化
更新： 问题不在驱动程序中。以前可以正常工作。戴尔笔记本电脑附带所有驱动程序问题出在附加驱动程序管理器中。经过一些操作后，它失败并出现错误。现在，我尝试更改名为oem-bluez-自动启用出现错误后，此设备从列表中消失，就像之前的 wifi 一样

可以修复吗？

要清除无线的‘附加驱动程序’，请打开终端并执行以下操作：
sudo apt-get purge bcmwl-kernel-source
重启。
