我正在寻求帮助，让我的 Broadcom Wlan 卡在装有 Ubuntu 的笔记本电脑上运行。到目前为止，我都无法让它工作。我目前尝试的解决方案：1. 使用可通过 ubuntu 附加驱动程序菜单安装的附加驱动程序 2. 使用 ndiswrapper 和适用于 BCM4313 的 Windows XP 驱动程序
这两种解决方案似乎都有相同的问题。您可以扫描可用的 WLAN（iwlist 扫描）。ubtuntu 和 kubuntu 的 WLAN 前端也可以找到 WLAN。但无法成功连接到它们。最后，我使用 wicd-client 前端进行了测试。
问题：如何修复此问题以便能够连接到网络？如何查看问题所在？
