¿Cómo puedo resolver problemas de arranque dual en MacbookPro (Ubuntu) WIFI?

¿Tengo instalación en MacbookPro 2016 con arranque dual, MacOs y Ubuntu? No tengo conexiones wifi, solo con LAN (a veces). Intento algunos comandos que encuentro, pero no hay solución. Gracias.

Tengo el mismo problema en MacBookPro13,2 con wifi:

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

He instalado Ubuntu 18.04 de arranque dual y el comportamiento es que, aunque puedo ver una red wifi de 2 GHz (no de 5 GHz), cuando me conecto, sigue pidiendo la contraseña, incluso si se introdujo correctamente.

Tengo el mismo hardware wifi:

lspci -nn | grep Network
02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 02)

lspci -nnk | grep 0280 -A3

    Kernel driver in use: brcmfmac
    Kernel modules: brcmfmac

Espero que brcmfmacel conductor me apoye BCM43602 [14e4:43ba] (rev 02).

Tengo los mismos errores cuando brcmfmacse carga el controlador:

sudo rmmod brcmfmac
sudo dmesg -C
sudo modprobe brcmfmac

No existen tales archivos en mi /lib/firmvare:

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

Esto es lo que tengo:

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

Encontré varios foros de discusión donde la gente decía que habían conseguido que este hardware funcionara.

Probé varias soluciones en Ubuntu 16.04, que no funcionaron, luego me di por vencido y cambié a Ubuntu 18.04, con la esperanza de que sea más nuevo y se adapte mejor al hardware. Todavía no funciona. Creo que intentaré nuevamente algunas de las soluciones descritas.aquí:

Hasta que esto funcione, estoy conectado por cable, usando un dispositivo USB a eth, pero me alegraría mucho que el wifi funcionara.
