我通过以太网电缆连接到互联网,并想在运行 ubuntu server 22.04 的 macbook air 2019 上启用 wifi。我的 pciid 如下:
73:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4377b Wireless Network Adapter [14e4:4488] (rev 04)
我查阅了一些现有资源来解决这个问题,但没有找到任何关于 broadcom 4488 的说明。
我尝试安装
bcmwl-kernel-source
firmware-b43-installer
但没有成功。任何帮助都值得感激。非常感谢!
编辑1:添加相关信息:
uname -r 给了我这个“5.15.0-91-generic”,
modinfo brcmfmac | grep 4488 没有返回任何内容。

我想说的是,我遇到了与完全相同的网络控制器 [14e4:4488] (rev 04) 完全相同的问题,并且我已经设法解决了该问题。
以下命令sudo dmesg | grep brcm
给出了以下输出:

我的系统上的问题是固件。只需下载最新版本的 deb 文件即可从这里。
现在将此文件放入/lib/firmware/brcm
。导航到那里并运行:
sudo dpkg -i apple-firmware.deb
然后重新启动。现在问题应该已经解决了。
