我正在使用 Edup Wifi 适配器型号 AC1661，使用Ubuntu 20.04内核版本5.11.0.41。我按照说明从下载并安装驱动程序此链接。当我将适配器重新物理插入时，驱动程序可以工作。我可以连接到网络。但是一旦我重新启动系统。它根本无法连接到网络。
这是 lsusb 的结果

这个问题有一些重复，但没有一个提供解决方案。有些票建议更改 grub 文件。我就是这么做的
blue@blue:/etc/default$ sudo cat grub
[sudo] password for blue:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 intel_idle.max_cstate=1 net.ifnames=0"
GRUB_CMDLINE_LINUX=""

我还创建了一个 .link 文件
blue@blue:/etc/network$ cat 10-wlan0.link
[Match]
MACAddress=e8:4e:06:96:e3:5f
[Link]
Name=wlan0
这里有日志对于 networkManager 未连接时日志当我能够连接到 wifi 时
知道为什么会发生这种情况吗？我该如何解决？
