 -> I have a question with regards to my modems login speeds. I have a Dual Std.

 -> I have a USR Courier Dual Standard v.FC, v.34 28.8k modem.  I have had it
 -> for about a month now, and I have not ONCE made a connection to another
 -> 28.8k modem, even another v.34 at more than 26.4k....  I even got a short
 -> 2ft. serial cable.... still, no more than 26.4k..... what do you think the
