I had the wireless (AirPort) working on my MacBook Pro 8.1 with a
dual boot MacOS/Debian setup without any difficulty for a couple of years.
A couple of days ago, I decided to try MacOS to configure a new modem,
as the wired connection in Debian would just show "connecting"... and
sit there. I very very rarely use MacOS... but I figured I'd try it for this.
To my surprise, the wired connection worked in MacOS, and I also connected
with the wireless to a router in MacOS. I rebooted into
Debian... and since that the wireless has not worked. The wireless
continues to work in MacOS. I am currently connecting with a wired
connection (in Debian).
I previously had the wireless configured with the b43 driver.
The install of the b43 driver is straight forward:
# apt-get install b43-fwcutter firmware-b43-installer
COMMENT:
I tried un-installing and re-installing. It didn't help.
I am running out of ideas of what to try. The situation is
unusual... as I had the wireless working previously.
I have only found one vaguely similar description related
to VMware (
http://askubuntu.com/questions/260209/networking-disabled-under-vmware-fusion-on-mac-os-x
).
I am not using VMware. The dual boot is done with rEFIt.
Here are a few things I tried/looked at:
---------
# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
COMMENT:
No blocks appear to be present.
I vaguely remember reading that MacOS puts network cards into some sort of
suspended mode... and they don't work afterward. I read this a couple of
years ago. I also have a MacMini... not sure it is in association with that.
In any case, I can't find anything for this vague recollection... possibly
imaginary problem.
Working the theory that MacOS screwed the network card... which is my
working theory (due to the temporal association):
I booted into MacOS -- and disabled the AirPort... rebooted into
Debian. Wireless still broken.
networksetup -setairportpower en1 off
Described here:
http://osxdaily.com/2011/05/31/enable-disable-airport-wireless-connections-command-line/
I booted into MacOS -- enabled the AirPort... rebooted into Debian.
Wireless still broken.
It should be noted that I rarely booted into MacOS into the past.
Preceding said, this is the first time since upgrading to Debian
'jessie'.
Any thoughts on reseting the wireless card from MacOS?
I did find something on that here:

I am somewhat confused that "lspci -vnn -d 14e4:" shows "Kernel driver

At least one other person seems confused about this:

COMMENT:
'iwconfig' detects the wireless card.
FURTHER COMMENTS:
-I also tried the 'wl' driver -- as described in detail
here: https://wiki.debian.org/wl
I did get the 'wl' driver installed and had purged the
'b43' driver. The wireless didn't work.
-I re-started the network between with: /etc/init.d/networking restart

COMMENT:
When I first looked at the file
(/var/lib/NetworkManager/NetworkManager.state) it showed
'WirelessEnabled=false'. I changed it to 'WirelessEnabled=true'. It
has stayed as 'true'...
even after reboots.
