This card should be the latest that Socket makes, I just bought it, and
the "Rev" version is "G". The card is software upgradable, but my
understanding is that the latest firmware is version G.

Do you know of a newer card that they make?

By default my card shows:
 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1
 (Seems to be missing only HV2, HV3)

I am able to get a connection if I only turn on DH5, but here at work I'm
unable to get good phone service for testing. When I go home I'll check it
where I get five bars of service to see if forcing the largest packet size
will give me higher speed...
