Hi B43-dev,
I am having trouble with the wifi card in my macbook pro 2012. It's a
BCM4331 and it hangs on ssh sessions.
I noticed it documented here.
https://wiki.archlinux.org/index.php/broadcom_wireless#SSH_freeze_for_BCM4331_with_b43
Is there some testing I could contribute to help fix this?
Evan,
I do not have that card, thus I cannot test with that chip.
Given the age of the chips driven by b43, it is hard to imagine that there are
any undisclosed proprietary secrets buried in the code. Broadcom should open
source these old drivers.
What are the symptoms of the frozen sessions? Is there anything in particular
that you are doing when it freezes? Does the freeze require rebooting either of
the machines in question? Is anything logged in the dmesg output of either machine?
One useful test would be to run Wireshark to capture the data on the network
interface. That capture file might have information that you would not want to
share, but you should be able to supply only the last few packets.
A macbook of that vintage should be able to run wl. That may be your best option.
