我在台式机上使用 Netgear WN311B PCI 无线适配器。该设备在 Windows（双启动）下运行正常。
我已经在“附加驱动程序”中启用了 Broadcom STA 无线驱动程序。
这是我在 Wicd 对话框中启用无线时 /etc/log/syslog 的输出：

这是我运行“sudo iwlist eth2 scan”的结果：eth2 没有扫描结果
这是 lsmod 的输出：

我不知所措。我试过使用 wicd，但没有结果。我试过移除并重新安装卡。我试过移除驱动程序并对其进行 modprobing。我试过禁用 STA 驱动程序。
我究竟做错了什么？
答案1
我的笔记本电脑也出现过同样的问题。安装后，我必须使用有线连接并卸载 Broadcom Sta 驱动程序，然后安装b43-fwcutter包。您还需要固件-b43-安装程序包。可以下载软件包和依赖项并手动安装，但通过有线适配器安装效果更好。
