Broadcom Corp. BCM4313 无线在 Ubuntu 12.10 中未检测到

Question

我将我的 Toshiba PORTÉGÉ 从 Precise(12.04) 更新到 Quantal (12.10)。更新到 Precise 无线设备后工作正常。但更新无线设备后，网络管理器未检测到。

该lspci命令说：

以太网连接工作正常。我尝试安装，firmware-b43-installer但它说：

$ sudo apt-get install firmware-b43-installer
...

我也执行这个，这是输出：

    Hard blocked: no

我在http://linuxwireless.org/en/users/Drivers/b43 中检查了模型：

BCM4313 - chipset uses unsupported LCN PHY, we work on it

我在视觉环境中配置了私有驱动程序，来自 Broadcom 802.11 Linux STA 无线驱动程序源，bcmwl-kernel-source但也不起作用。

Answer 1

我相信 bcmwl-kernel-source 适合您的设备。让我们再试一次：

sudo apt-get install linux-headers-generic
sudo apt-get install linux-headers-$(uname -r)
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

你应该准备好了。
