Help please. I just activated ATTWS on a V551 phone. Under Network Settings, one of the options is Speed. There are 4 choices: slow, medium, fast and continuous. It has been defaulted to Medium. I live in the Central NJ area, so what is the best selection for me?

Can you please also explain what this is and the differences in the selection? I called ATTWS Customer Service but they were clueless.

Thanks in advance.
