[Soekris] Multiple Wireless Network Card Problem

[David Burke]

I have a Soekris NET4526 board with two wireless (mini-pci) cards running a
stripped down version of RedHat Linux.  The software that I am running was
written by another company so I am not terribly intimate with their
software.  I will tell you that it is configured to operate as a router.

My problem is that the board and software works fine when I have either of
the two wireless cards installed in the Soekris board by themselves, but as
soon as I install the other card such that both are installed
simultaneously, I can't get either of them to work.  What I mean by this is
that the "Signal Level" reported by iwconfig goes from say -47 dBm with only
one card installed to -95 with both installed.  Each of the two wireless
cards are setup for completely different frequencies (i.e. one at 4.9x GHz
and the other at 5.8x Ghz).

I have verified that they are both configured properly using iwconfig and
ifconfig.  The most baffling thing is that I would think that as long as one
of them is disabled (i.e. down) that the other one would work just like it
was the only one installed in the board but it doesn't.

Any help would be greatly appreciated.
