[driverloader] Interference between non-overlap channels?

[Chris Ma]

Dear all,

I have setup 4 wireless network cards on 3 computers, i.e. two
computers each have one wireless NIC (say A and B), and one computer
with 2 wireless NICs (say C). I would like to form 2 wireless networks
(i.e. A-C and B-C) using the NICs for testing purpose.

I found that even though I set the channels of the two networks to be
1 and 11, which are supposed to be having no overlap in frequency, the
total throughput of the two networks is just roughly the same as a
singular one, i.e. it looks as if the two networks are sharing the
same channel which is not true.

It is also found that the "Invalid misc" in "iwconfig" increases quickly.

I am using Linux Fedora Core 3 with kernel 2.6.12-1.1372_FC3.stk16,
and the NICs are all Buffalo WLI2-PCI-G54 using bcm4306kfb chip.

Are there any settings I have missed to cause this problem?

Thank you for any suggestions.

Regards,
Chris
