更新 2：正在尝试从这个答案中命令 -Ubuntu 22.10 MT7622 无线设备无法工作
但这没有帮助
答案1
创建一个名为的新文件/etc/modprobe.d/mt7921e.conf并将其用作其内容
alias pci:v00000b48d00007922xsv*sd*bc*sc*i* mt7921e
然后创建文件/etc/udev/rules.d/99-mt7921e.rules并添加
SUBSYSTEM=="drivers", DEVPATH=="/bus/pci/drivers/mt7921e", ATTR{new_id}="0b48 7922"
保存并退出然后运行sudo depmod -a
Reboot 看看是否有效
