There should be no difference between these two as far as the Internet 
connection is concerned unless there is some problem on your local 
network, or there is some configuration difference between the 
computers on the different links.

What is your topology?

What are these counters looking at?

Are these pings? to where? Are you pinging your local ISP's gateway to 
your DSL connection? or something up-stream from that?

I also forgot to ask earlier -- is this a new connection? If it is, the 
problem is most likely with the ATM cloud behind the DSLAM which 
connects you to your ISP. My experience has been that it takes "a 
while" (more than one iteration) to get that circuit provisioned 
correctly... especially if the changes don't get backed up and they 
have to reload the CO switch with yesterday's parameters.
