Hi Rafal,
I bought some 43224 cards to begin playing with the firmware. Unfortunately I
have problems with the throughput that is really low. Kernel is the latest from
wireless git and firmware comes from broadcom-wl-5.100.138. I see that the
transmitted power is low, I monitored it with a spectrum analyzer and it
confirmed. A lot of packets are lost given the low power and minstrel always
select 1Mb/s. When receiving with the 43224 in monitor mode, I see that it
receives only a few of the frames that are received by a close 4318-based box:
the reported power levels are low too. Please find attached all info about
kernel/firmware and devices below.
I tried all the four cards I have and they behave the same: find a photo of one
of them here

I tried the cards on a MacBook White, on an Intel Atom based motherboard, Intel
Pentium, and AMD Sempron, and I always got very low throughput. The same cards,
with the same antennas (everything untouched) but with brcmsmac work well and
the spectrum analyzer reports "normal" emitted power levels.
KR,
