如何解决 MacbookPro(Ubuntu) WIFI 上的双启动问题？

  • 772

我在 MacbookPro 2016 双启动 MacO 和 Ubuntu 上安装了吗？我没有连接wifi，只有局域网（有时）。我尝试了一些我找到的命令，但没有解决方案。谢谢。

    我在带有 wifi 的 MacBookPro13,2 上遇到了同样的问题：

    sudo dmidecode -s system-product-name
MacBookPro13,2

    我已经安装了 Ubuntu 18.04 双启动，行为是虽然我可以看到 2GHz wifi 网络（没有 5GHz），但当我连接到它时，它一直在询问密码，即使它被正确引入。

    我有相同的wifi硬件：

    lspci -nn | grep Network

    Kernel driver in use: brcmfmac
    Kernel modules: brcmfmac

    期待司机brcmfmac支持BCM43602 [14e4:43ba] (rev 02)

    brcmfmac驱动程序加载时我有同样的错误：

    sudo rmmod brcmfmac
sudo dmesg -C
sudo modprobe brcmfmac

    我的/lib/firmvare 中没有这样的文件：

    brcm/brcmfmac43602-pcie.Apple Inc.-MacBookPro13,2.txt
brcm/brcmfmac43602-pcie.txt

    这是我所拥有的：

    sudo ls /lib/firmware/brcm/brcmfmac43602*
/lib/firmware/brcm/brcmfmac43602-pcie.ap.bin
/lib/firmware/brcm/brcmfmac43602-pcie.bin

    我发现了各种讨论论坛，人们说他们让这个硬件正常工作。

    我在 Ubuntu 16.04 上尝试了各种解决方案，但都不起作用，然后我放弃了，并切换到 Ubuntu 18.04，希望它更新并更好地应对硬件。还是不行。我想我会再次尝试这里描述的一些解决方案：

    在此之前，我使用有线连接，使用 USB 到 eth 加密狗，但如果 wifi 能正常工作，我会很高兴。
