我的笔记本电脑上似乎安装了 BCM43142 的驱动程序：
lspci -k
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
Subsystem: Dell Wireless 1704 802.11n + BT 4.0
Kernel driver in use: bcma-pci-bridge
kernel modules: bcma
但是，似乎没有与该设备关联的无线接口：
ip link
不输出无线设备的任何信息。我查看了 Archlinux 文档，它没有说明如何将接口（即 wlan0）连接到无线设备。知道我将如何解决这个问题吗？
dmesg| grep bcma
更新：我得到以下dmesg输出

安装Broadcom-wl-dkms包裹。
yaourt您可以使用（不推荐使用yay）从 AUR 安装它请查看 AUR 助手的完整列表：
yaourt -S broadcom-wl-dkms
卸载冲突的模块。
rmmod b43
rmmod ssb
rmmod bcma
加载wl模块：
modprobe -r wl
modprobe wl
