Will attempting class 1 w/ the same modem in this case make any difference?

You will excuse my ignorance on this topic. I have never found a good
explanation of class 1 vs. class 2/2.0 which clearly defined the
consequences/advantages of using class 1. From what I have read, I deduced
(perhaps incorrectly) that class 1 was a bit like using a winmodem. They are
ok if your computer isn't doing alot of other things while you are using it
or if you have a real time operating system which can guarantee enough time
to the modem but when things get hairy you want hardware implementation.

Regards,
Rob
