I installed ubuntu 14.04.02 on a new macbook pro 11,5 (15 inch), but wifi doesn't work.
Here are some information about the wifi adapter.
$ lspci -nn | grep 0280
04:00.0 Network controller : Broadcom Corporation Device [14e4:43ba] (rev 01)
$ sudo lshw -C Network
description: Network controller
product: Broadcom Corporation
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:04:00.0
width: 64 bits
capabilities: pm msi pciexpress bus_master cap_list
configuration: driver=wl latency=0
resources: irq:18 memory:b0800000-b0807fff memory:b0400000-b07fffff
I followed the answers of the following questions, wifi still doesn't work. I tried many times, the final results are the same.
I didn't see the chipset id, but I think [14e4:43ba] should be the pid:vid of wifi adapter. I didn't see much discussion about this device. Hope anyone can share your experience of how do you get this work.
Thanks in advanced!
PS: I have a usb to ethernet adapter, I finished apt-get update and upgrade, it doesn't help.
