我在 MacbookPro 2016 上安装了双启动 MacOs 和 Ubuntu？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 MacBookPro13,2 上使用 wifi 时也遇到了同样的问题：
sudo dmidecode -s system-product-name
MacBookPro13,2
我已经安装了 Ubuntu 18.04 双启动，其行为是，虽然我可以看到 2GHz 的 wifi 网络（没有 5GHz），但是当我连接到它时，它会不断要求输入密码，即使密码输入正确。
我有相同的 wifi 硬件：
lspci -nn | grep Network
02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 02)

我希望brcmfmac司机支持BCM43602 [14e4:43ba] (rev 02)，
我在驱动程序加载时遇到同样的错误brcmfmac：
sudo rmmod brcmfmac
sudo dmesg -C
sudo modprobe brcmfmac

我的 e 盘里没有这样的文件/lib/firmvar：
brcm/brcmfmac43602-pcie.Apple Inc.-MacBookPro13,2.txt
brcm/brcmfmac43602-pcie.txt
以下是我所拥有的：
sudo ls /lib/firmware/brcm/brcmfmac43602*
/lib/firmware/brcm/brcmfmac43602-pcie.ap.bin
/lib/firmware/brcm/brcmfmac43602-pcie.bin
我发现各种讨论论坛上都有人说他们让这个硬件运转起来了。
我在 Ubuntu 16.04 上尝试了各种解决方案，但没有奏效，然后我放弃了，转而使用 Ubuntu 18.04，希望它更新，能更好地处理硬件。仍然不起作用。我想我会再次尝试一些描述的解决方案这里：
在它工作之前，我使用有线连接，使用 USB 转 eth 加密狗，但如果 wifi 可以工作我会非常高兴。
