Jason - I really doubt the problem is in the PM2 units - we have had several
clients who reported just what you are talking about and it turned out to be
their software (mostly Win95 version 950 or 950A - which has some bugs in
the DUN and networking code). Once the client got the OS problems
straightened out the download problems evaporated as well. We have several
PM2 units fully loaded and running at 155200 on the ports without any
problems...
As for software compression - turn that back on as you are not gaining
anything without it and really just penalizing the other customers in
possible speed....
