我知道很多关于如何让 Broadcom wifi 卡与 bcmwl-kernel-source 或 firmware-b43-installer 驱动程序配合使用的帖子。我已阅读所有内容并尝试了所有方法，但均未得到结果。请帮忙！
我有 BCM4322 [14e4:432b]。我尝试（从 lubuntu 16.04 的全新安装）删除 bcmwl-kernel-source 的 --purge，安装相同的驱动程序，然后重新启动并确保在“软件和更新”的“其他驱动程序”选项卡中选择了该驱动程序。这不起作用后，我尝试删除 bcmwl-kernel-source，然后安装 firmware-b43-installer。rfkill 列表显示没有阻止任何内容。此外，安全启动选项已停用。
有什么想法吗？如果您需要任何其他信息，请告诉我。

答案1
您已尝试了该设备普遍接受的驱动程序套件 bcmwl-kernel-source。我们已确认您安装了最新版本。此驱动程序产生了经常出现的错误，通常针对您的确切 14e4:432b 设备：
ERROR @wl_cfg80211_scan : WLC_SCAN error (-22)
<snip> and many others
您已尝试使用 b43 和 ssb 驱动程序套件并安装了所需的固件。在创建无线接口并且网络管理器尝试管理它时，也会导致错误：
state change: unavailable -> disconnected (reason 'supplicant-available') [20 30 42]
我们从别名中知道，驱动程序 brcmsmac 和 brcmfmac 都不能驱动您的设备。
我相信你的选择现在缩小到两个：
购买完全支持的 USB 无线设备。这篇文章可能有助于您选择一款：https://ubuntuforums.org/showthread.php?t=2359573&p=13639455#post13639455
尝试 17.04 和 14.04 的实时 USB 或 DVD，看看 Ubuntu 的更高版本甚至更早版本是否可以运行。
很遗憾我目前无法让您的设备正常运行。
