运行lubuntu 16.04 LTS的macbookpro7,1上没有wifi
我知道有关如何使用bcmwl-kernel-source或firmware-b43-installer驱动程序的broadcom wifi卡的许多post。 我已经阅读了所有内容，并尝试了所有内容，但没有得到任何结果。 请帮忙！
我有BCM4322 [14e4：432b]。 我尝试（从干净安装的lubuntu 16.04）删除 – 清除bcmwl-kernel-source，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”选项卡中选择了驱动程序。 在此操作无效后，我尝试删除bcmwl-kernel-source，然后安装firmware-b43-installer。 rfkill列表显示没有被阻止。 此外，还会停用安全启动选项。
有任何想法吗？ 如果您需要任何其他信息，请告诉我。
