BTW: I will install in a short time an wrap board with 2xcm9 working in
5.8GHz band.
Will let you know how it is doing the job.

Hi Edwin
How are you?
I had 2 radio cards in 5.8GHz running with 10mbps throughput without
any problems
if I remember right BUT with wrap!!
At the moment I have wrap with 5.8 and 2.4 cards in use in the same
wrap..
If you have still a wrap board try it with wrap instead of alix...

Sean,
Thanks for the thoughts. While noise is possible, the radios are 5.2
and 5.8 bands respectively and 5Ghz is non-overlapping as well so I
wouldn't think the effect would be this dramatic. I've run 2 2.4GHz
cards in a common box and did see some throughput effect but nothing
like I've reported here. The cpu load doesn't go up much though the
ksoftirqd does consume a fair number of cycles. I also wonder
whether the board's design is a factor wrt to the minipci bus, hence
the posting. Another possible explanation is the driver in handling
the interrupts/dma transfers on the bus.
I have a 3 ethernet port ALIX that I will test this on using only the
wired interfaces to rule out/in anything to do with madwifi, hal,
atheros chipset, etc.

It could be radio noise in the box, even though you may be using
different channels.
It could also be cpu. What percentage does your cpu get up to in top
while running the tests? It would also be good to find out how much
the minipci backplane in the alix will support.
