Just wanted to follow up and let everyone know that my laptop DUN via USB cable with the 6700 is flawless and is pretty fast via the EV-DO.

Afraid to install the bluetooth again for fear of having to mess everything up all over again. I did get a reply from the manufacturer and the tech there implied that the bluetooth adapter establishes its own IP address that could interfere with my laptop's IP address. This is something I've never heard of and I'm wondering how to avoid the conflict so I can use bluetooth to establish DUN that way without any INTERNET issues.
