更新：我决定退回该卡，因为到目前为止似乎没有任何 Linux 固件支持。
我的 Wifi 卡（ASUS_PCE-AC88）无法在 Ubuntu 16.04 上运行，该卡未显示在网络管理器中。
我专门创建了这个问题，因为我[14e4:43c3]还没有找到任何关于 ubuntu 驱动程序的好信息。askubuntu 上关于 broadcom 驱动程序的帖子 (安装 Broadcom 无线驱动程序) 没有列出我的版本。
如果您需要更多信息，请告诉我。
我已经尝试安装bcmwl-kernel-source并加载模块 wl，sudo modprobe wl但导致启动时出现错误：
ERROR @wl_cfg80211_detach : NULL ndev->ieee80211ptr, unable to deref
我正在运行以下内核版本：4.4.0-72-generic

答案1
我知道这是一个老话题，但现在最新版本的 Ubuntu 已经支持这张卡了。
我刚刚安装了 Ubuntu服务器19.04，该卡开箱即可使用。
谨防新的安装程序根本不起作用，启动时崩溃，我无法工作，因此请使用备用安装程序。
答案2
正如您从链接的 Wikidevi 页面中看到的，您的设备的正确驱动程序是韓國；不是专有驱动程序韦由 bcmwl-kernel-source 提供。在消息，显示驱动程序已加载，但未找到所需的固件。
我相信最新版本的Linux 固件有需要的文件。通过以太网、网络共享或任何可能的方式建立有效的互联网连接，请打开终端并执行以下操作：
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.164_all.deb
sudo dpkg -i linux-firmware*.deb
重新启动并让我们看看：
