如何安装 Broadcom / STA 无线网卡(BCM43XX)

我最近在朋友的笔记本电脑上安装了 Ubuntu 12.10,但无法让它与他的路由器无线配合使用。我可以连接到互联网,并通过以太网连接正常使用,但我尝试设置的许多无线连接都将其“上次使用”显示为“从未使用过”。我不确定降级到工作版本或让当前版本连接需要哪些信息/图像。

希望这有帮助。

答案1

该设备无人认领。我推测这意味着没有驱动程序正在使用它:

  • 要么你有 Broadcom 开放驱动程序(它们在内核中,所以很可能是这种情况),但你没有 Broadcom 的二进制固件,你可以通过b43-fwcutter软件包。如果是这种情况,您应该在内核日志 ( dmesg) 中看到一些相关的错误消息。

  • ...或者你根本没有驱动器,你必须用它编译内核,或者安装 Broadcom 的专有内核,broadcom-sta

答案2

我在使用 Broadcom BCM4311 时也遇到了类似的问题。以下链接帮我解决了这个问题:

安装驱动程序后 BCM4311 无线无法工作

答案3

您需要安装无线驱动程序。

为此,您需要连接到互联网。

进入菜单并搜索“软件源”。应该会弹出一个写着“软件源”的按钮,你可以点击它。点击它。

这可能需要一两分钟,但软件源窗口很快就会出现在屏幕上。在此窗口的顶部,您将看到选项卡,其中一个选项卡显示“其他驱动程序”。单击它。

您将看到一个设备列表,在设备列表下方,是这些设备可能的驱动程序列表。由于您要查找的是无线驱动程序,因此只有一个驱动程序。找到您的 Wi-Fi 设备,单击所需的驱动程序,然后单击应用。输入您的密码,驱动程序应开始下载。下载完成后,您的 Wi-Fi 应立即正常运行。
