我将此设备连接到带有 Debian buster / sid（目前是 Debian 测试）的 PC，安装了驱动程序（mt7601u）和 wirmware aptitude intsall firmware-misc-nonfree firmware-realtek，但无法连接到接入点，它们的列表可用，但连接确实不会发生。

我还尝试在 NetworkManager GUI 中禁用 IPV6，但没有帮助。
我还从 USB 闪存驱动器启动到 Linux Mint 和 Ubuntu，一切正常。
如何使适配器在 Debian 中工作？
设备驱动程序在系统中创建了一个太长的设备名（例如.wlxd46e0e1f1528）并且linux不能正确使用它（例如它可以连接，但无法获取ip）。作为问题的解决方案：
