One consideration to upgrading your modem is speed the other is fax capability
(cheaper that a fax machine). The maximum speed for analog modems is 58.8 KBS. (KBS
stands for Kilo Bits per
Second)
If your current modem is a 58.8 KBS then there is no reason to upgrade,
if you
don't have a fax or voice capability and would like to have it then you could do
that.
If you have a 58.8 KBS modem and are not getting that speed when connecting it
more than likely is your phone line. Have the phone company check you phone
line, some phone companies will not guarantee more than 28.8 KBS on a analog
phone line.
