whats the baud rate of the modem of the computer
Data Transfer rate in modems is measured in Bits per second (Bps).
A faster modem will provide for faster faxes,since the data is being processed at a faster rate.
A NIC is capable of receiving and transmitting data at a faster rate than a modem. However, if the NIC is connected to a network which is powered by a modem, they will both run at the slower speed of the modem.
Diamond SupraMax DSL642WLG Wireless DSL Modem Router is a highspeed modem ideal for DSL connection. It allows the maximum 24 Mbps downstream data rate and up to 1024 Kbps upstream data rate, making it one of the fastest modems for its price.
A regular modem will carry data at the rate of virtually one terabyte in optimal conditions. However dedicated T1 lines will always carry it at that rate and so are quicker.
The speed at which data is transferred using a modem is called the "baud rate" or "bit rate." It is typically measured in bits per second (bps) and indicates how many bits are transmitted in one second. This speed can vary depending on the type of modem and the quality of the connection. Higher baud rates generally allow for faster data transmission.
Bandwidth of an optical fiber determines the data rate.

Increase the Data Transfer Rate of your Modem. If it is a wireless connection, re-position your wireless modem. You can monitor your changes through some Connection Wizard.
