I had similar issue on Dell XPS 15 with:
02:00.0 Network controller: Broadcom Corporation BCM43602 802.11ac Wireless LAN
SoC (rev 01)
Subsystem: Dell BCM43602 802.11ac Wireless LAN SoC
Kernel driver in use: brcmfmac
Kernel modules: brcmfmac
I resolved this by loading the proper firmware into kernel. I am using
Refind with support of UEFI bios, so my kernel is self loaded (no Grub
or Lilo, etc.) including the firmware for specific hardware.
Here are some hints how I resolved non-working wifi. The .txt file is
not available for some of brfmac devices (as my case as well).
Look here for detailed analysis and resolution, be patient as was also
resolving how to properly load the firmware into kernel:
