我有一台相当新的 Macbook Pro,最近我在上面安装了 Ubuntu 15.10。不幸的是,我似乎无法连接到 WiFi。
我通过终端确定了芯片组:
$ lspci -nn | grep 0280
03:00.0 Network controller [0280]: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)
我也看不到任何 5GHz 网络(不确定这是否是相关问题)。我尝试按照以下解决方案来修复它这里,我下载了brcmfmac43602 固件来自Linux固件git repo,然后将其复制到/lib/firmware/brcm
。重新启动我的机器后,我仍然无法连接到WiFi。
编辑:
一些诊断如下

似乎无法加载固件。另外,为什么我的网络接口从 重命名为wlan0
?如果可以的话wlsp3s01
,我想保留它wlan0
