It's pretty hard to slip new tech by me, so I'm just going to assume that we're talking about a WAN miniport here.
Sounds like your modem is trying to dial up a connection before the system defaults to a broadband connection. Try this...
Start ---> Control Panel ---> Internet Options ---> Connections Tab ---> check the box labeled "Never dial a connection" ---> Apply ---> OK ---> reboot.
That should do it. If not, hit us back. Good Luck/Happy Holidays!
Thank you vig1lant3, I just did it as you suggested and I think that will make it.
Thanks a lot for dedicating time to help me.
