Any device or system that generates an electromagnetic field in the radio frequency spectrum has the potential to disrupt the operation of electronic components, devices and systems in its vicinity. This phenomenon is known as ElectroMagnetic Interference (EMI), also known as Radio Frequency Interference (RFI). It may frequently cause packet loss because of the abnormal operation of your modem and other devices.

The internal circuits of personal computers generate RF fields. Also, cathode ray tube (CRT) displays generate EM energy over a wide band of frequencies, monitors in other words. These emissions can interfere with the performance of sensitive devices (such as your modem) nearby. If you have a sensitive device of any kind and use it at the same time as you operate your personal computer, you will probably hear RF noise in the receiver that originates in the PC system.
