If by "duplex mismatch" you mean that I had a box running base 10 that
was slowing down the entire network, that makes sense, but all the nics
I'm using are capable of 100 and the router indeed had the proper LED
color to show that it was proportedly running at full duplex. I will
concede, however, that my router may be a piece of crap and not capable
of switching at full duplex. I don't know. Maybe I'm just blowing
bubbles. ;-)
