Re: Interference between non-overlap channels?

Hi,

on some systems with wireless cards based on the Broadcom chipset, a few 
users have reported that the 'Invalid Misc' value in the output of the 
'iwconfig' is increasing quite rapidly. So far, this known problem 
doesn't seem to be harmful for a common usage of DriverLoader.

Since this is a throughput problem, it is possible that DriverLoader is 
not the source of the problem. Did you tried with a similar setup but 
under Windows to see if you have the same problem?
