[NCLUG] system hangs for 5-10 seconds every few minutes

[Benson Chow]

I had something like this happening with wireless at one time, and fixed 
it by mucking with the router config, though the wireless card probably 
also could be changed to fix.  I believe it was something to do with 
beacon transmissions.  Of course this is wrong if you can't reproduce this 
with another machine with the same wireless adaptor.

AFAIK this likely is some sort of timing expiration bug with the wireless 
driver based on what I'm seeing.  Try moving the antenna and make sure it 
gets good signal.

Another datapoint is to see is if you witness this stalling on console - 
try hooking up a console - if you don't see it on console, then the 
network layer is highly suspect.
