I have an
HP Mini 210-1000 with a troublesome
[14e4:4315] LP-PHY rev 01 wireless card. I've done some analysis of the
b43 driver's performance with different firmware versions  in response to discussion  about the Archwiki documentation on obtaining the firmware .
I also have a
MacBookPro7,1 and created the first version of the Archwiki page for it  in hopes of gathering information, but have since given up.
Yay linux! :)
