禁用 PCI 网络设备并使用 USB Ubuntu 20.04

我正在尝试在 Ubuntu 上通过板载 WiFi 使用 TP-Link AC600 USB 加密狗。

我已经安装了驱动程序并且设备正在被识别。

在 UI 中，如果我尝试通过 PCI 断开 USB Wifi，它们都会断开。如果我用来rfkill阻止其中一个设备，我会失去连接。

以下是一些系统信息：

我建议您将内部设备的驱动程序列入黑名单。从终端：

sudo -i
modprobe -r iwlwifi
echo "blacklist iwlwifi"  >>  /etc/modprobe.d/blacklist.conf
exit

一切已准备就绪。
