Thanks for the link Chris. I'll try to get the steps to push the NIC card controlling the etherdongle above the regular one, so our utilities do work. Of course my setup is always a bit more challenging, running Windows and all the software inside an OS X window (through fusion). So far, I have yet to see an hardware incompatibility, so those steps might work. Of course the Network stack is controlled by fusion directly, so might have to fight a bit more there.
My current solution has been to swap the network cable whenever I needed to use the Lynx utilities. It's all on my desk, so not that big of a deal, but I liked the convenience of the software switch to select the com port when I was using the USB dongle.
