苹果笔记本用的一般都是博通的网卡？
可以试试 sudo apt install broadcom-sta-dkms 安装下驱动

最好执行下 lsusb 和 lspci -nn 看看蓝牙适配器以及无线网卡的硬件 id，才能知道需要啥驱动

lspci -nn

只有这些信息

也许是主板缺什么驱动。

蓝牙驱动型号，内核版本方便说一下嘛？

02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4350 802.11ac Wireless Network Adapter [14e4:43a3] (rev 05)

这是 BCM4350 的博通无线网卡，看上去不被 broadcom-sta-dkms 驱动包支持，但是我记得 V23 系统里预装了这个驱动模块，可能会导致一些异常。

P.S. 参考 networking - Ubuntu 16.04 driver for Broadcom Limited BCM4350 802.11ac Wireless Network Adapter [14e4:43a3] (rev 08) - Ask Ubuntu

解决方案（？）：

• 终端执行 sudo apt purge broadcom-sta-dkms 卸载博通网卡闭源驱动 并重启，应该就可以正常使用？理论上重启后会自动加载内核中的 brcmfmac 驱动模块
• 如果不行，再继续执行 sudo modprobe brcmfmac 看看

P.S. 一般苹果的笔记本用的都是 BCM4360 或者 BCM43142 来着，BCM4350 也就 Dell 会用吧......
