尝试在旧的 HP G7000 笔记本电脑上安装无线功能，但无济于事。已安装 firmware-b43-installer，但仍然无济于事。
这是 wifi 卡：
~$ lspci -nn -d 14e4:
01:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 02)
以下是我目前所做的：
sudo apt-get purge bcmwl-kernel-source
sudo apt-get update
sudo apt-get install firmware-b43-installer
sudo modprobe -r b43
sudo modprobe b43
现在的输出是：

答案1
您在安装所需固件时出现了问题。请确保您已通过以太网或任何其他方式连接到互联网。打开终端并执行以下操作：
sudo apt-get install --reinstall firmware-b43-installer
这需要一点时间，所以请耐心等待。完成后，请检查：
ls /lib/firmware/b43
您应该会看到数十个固件文件。如果是这样，您应该已经设置好了。重新启动并告诉我们结果。
如果无法重新启动，则：
sudo modprobe -r b43 <---if it says it's not loaded, that's fine, just continue
sudo modprobe -r ssb_hcd
sudo modprobe -r ssb <---if it says in use, see lsmod for users
sudo modprobe b43
你的无线网络应该可以正常工作。
一旦安装了专有固件，该设备在 Ubuntu 中就能运行得很好。
