Actually, the broader the frequency band, the more information that can get through at a time, the faster the connection. That's why FM radio stations sound better than AM stations, and why cable modems and DSL are faster than a dial-up service.
The reason for this is due to the nature of digital data. A digital signal takes up a wide array of frequencies, with the width corresponding primarily to the speed of the signal. If you tried to transmit data at a higher speed than what a line is designed for, some of the higher frequencies would be attenuated, and you would start to get a lot of errors.
