HP G7000 笔记本电脑无法连接无线网络

Question

尝试在旧的 HP G7000 笔记本电脑上建立无线网络但无济于事。已经安装了firmware-b43-installer，但仍然没有。

\n\n

这是无线网卡：

\n\n

~$ lspci -nn -d 14e4:\n01:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 02)\n

\n\n

这是我到目前为止所做的：

\n\n

sudo apt-get purge bcmwl-kernel-source\nsudo apt-get update\nsudo apt-get install firmware-b43-installer\nsudo modprobe -r b43\nsudo modprobe b43\n

\n\n

以及现在的输出：

\n\n

Answer 1

您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

这需要一些时间，所以请耐心等待。完成后，检查：

ls /lib/firmware/b43

您应该会看到数十个固件文件。如果是这样，你应该已经设置好了。重新启动并告诉我们结果。

如果重新启动不可行，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

您的无线网络应该可以工作。

一旦安装了专有固件，该设备就可以在 Ubuntu 中正常工作。
