No Wireless quando si installa 14.04 su Macbook Pro

20

Quindi sto tentando di avviare dual-boot OS X 10.8.5 (sistema operativo nativo) e Ubuntu 14.04. Ho installato Ubuntu (evviva!) Ma dopo l'avvio su Ubuntu ho scoperto di non avere alcuna connessione di rete dal sistema operativo. Sono molto nuovo a Linux.

Ho notato alcuni post simili , tuttavia l'unica" soluzione "che ho visto finora è quella di avvitare la connessione wireless e acquistare un adattatore Ethernet-Ethernet. Se stavo usando questo computer a casa, andrebbe bene. Ma questo è in un ufficio ed è solo WiFi.

Esiste comunque l'adattatore wireless per funzionare?

Mac Book Pro, Retina, 13 pollici, fine 2012 CPU Intel Core i5 da 2,5 Ghz Memoria 8 GB

Si prega di fare:

sudo apt-get update
sudo apt-get install firmware-b43-installer

Riavvia se non si connette pubblica un nuovo file dallo script.

Nessuna connessione Internet:

Scarica il file b43updated.zip in una chiavetta USB quindi trascina il file sul desktop di Ubuntu. Fai clic con il pulsante destro del mouse e seleziona Estrai qui.

Apri un terminale e fai:

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/*  /lib/firmware/b43
sudo modprobe -rv b43 
sudo modprobe -v b43

se non si verifica il riavvio.

Ho avuto lo stesso problema su macMini

>lspci -nn
02:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

e questo ha funzionato per me:

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source
sudo apt-get install linux-firmware-nonfree b43-fwcutter firmware-b43-installer

e poi un riavvio
