我已经尝试了一段时间，想让我的无线网络在 Ubuntu 11.10 中再次工作，尽管在我安装当前版本的几个升级之前，无线网络在 10.04 中是可以工作的。我上过论坛，确保没有软块或硬块，未列入黑名单的 bcm43xx 驱动程序，删除了专有的 Broadcom STA 驱动程序，并安装了 B43 驱动程序，但这仍然没有帮助。我尝试了许多不同的解决方案，但似乎都不起作用。我的 lspci 输出如下。

您可能需要尝试重新安装对我有用的 bcm43** 驱动程序，转到系统 > 管理 > synaptic 包管理器。当屏幕出现时，单击重新加载，找到您的 broadcom 驱动程序，单击重新安装，然后重试。
