摘要：我插入了一个 USB wifi 适配器并被内核识别，但 UI 中没有任何地方可以配置它。
- 该计算机是使用 4 年以上的 HP 台式机（i7-4790S CPU、16GB RAM）。更多信息在最后。
我插入了 USB wifi 适配器。
Trendnet TEW-649UB v1.0R (I also have the DLink version of the same device.)内核识别了它。

不知道下一步该做什么，也不知道为什么这在互联网上基本上没有记录。

答案1
显然，我需要重新启动 NetworkManager。看起来我必须为每次启动都执行此操作。
sudo service network-manager restart
答案2
我对 Tails 也有同样的问题，但问题是硬件，所以解决方案可能不适用于您的笔记本电脑。我有 HP，我需要像这样将模块添加到黑名单中
sudo su
echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf
你需要重新启动。
它的作用是阻止加载负责 WI-FI 驱动程序的 acer_wmi 模块我什么的，我不记得细节了。您可能需要将不同的模块添加到黑名单，再次研究您的笔记本电脑型号。
