我正在运行 Ubuntu 20.04。我想启用 USB wifi 适配器。
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
我有两个我试过的适配器，Netgear WNA3100 和 Linksys WUSB6100M，我尝试添加几个从制造商支持页面下载的 Windows 驱动程序文件，使用ndiswrapper.
$ ndiswrapper -l
bcmwlhigh6 : driver installed
device (0846:9020) present
netuac8 : invalid driver!
netuac8x : driver installed
device (13B1:0042) present (alternate driver: ath10k_usb)
scmndisp : invalid driver!
我按照这个答案来接近这个答案，但答案是几年前的，这可能会导致我找不到的问题。例如，包ndisgtk不再存在。它“感觉”很近，但 wifi 无法正常工作。尽管操作系统告诉我它可以看到 USB 设备和驱动程序，但在搜索连接时我看不到 wifi 信号。两个 USB 适配器都可以在 Windows 机器上正常工作，我知道 wifi 路由器工作正常。任何帮助表示赞赏。

我也试过：
$ sudo mokutil --disable-validation
EFI variables are not supported on this system
因为我认为驱动程序签名是一个问题，但坚持如何在 EFI/UEFI 中重新启动（？？）所以我真的被卡住了。
