I'm using a usb frontech modem(VD56US) with winXP in my pc, the modem speed varies from around 40kbps to 45.2kbps.But in my office PC I'm using an external D-link modem DFM-562E(V.92 56000bps) and the speed is about 115 kbps. Is it bec' of the modem or phone line that I'm getting this difference in speed? Will I get faster speed if I use the D-Link modem in my pc? If so can any one recommend a better modem.
