I only can speak for iwn, run and the em thing in my machine. I am travelling with this hardware most of the time I have bought it. I hardly notice drops on the em interface connection to locally connected machines. I see a drop range from 0 to 100% when iwn is connecting to the same AP while run ranges from 0 to 10% at the same moment of time. But when I connect via iwn to a different AP and stay within 10m the drop rate is 0 again. With other words, it can be a problem caused how the actual hardware pieces connect to each other. It could be in your case that the PCI card has simply a better layout. I do not believe that on-board hardware is generally bad. Can you change the hardware this machine is talking to? Erich
