Maintaining best connection on WinXP Pro

[Ralph Sims]

I would like to keep my evdo card, my 802.11 adapter and my lan connection
all up and running simultaneously.  The object would be to have WinXP select
the "best speed" based on some criteria.  In that manner I think I can
seamlessly roam between networks and always be assured of the fastest
connection.  There has to be some helper app to do this, but Google didn't
yield anything useful except a registry hack which didn't work.

Here's what I'm seeing...  I connect via my LAN and get an IP using DHCP (or
static, depending).  I plug in the evdo card and my gateway changes to that
of the card.  I'd like to keep the LAN connection as the gateway and when I
unplug from it, drop to the evdo.  If I have the 802.11 nic enabled along
with the LAN and the evdo card and the ethernet NIC the evdo still takes
over.
