How far should a cable modem be placed from other electronic devices?

Placing a cable modem at least three feet away from other electronic devices is important for minimizing interference that can affect the modem's performance. Electronic devices, such as microwaves, cordless phones, and wireless routers, can emit electromagnetic interference (EMI) that may disrupt the modem's ability to send and receive signals effectively. By maintaining a distance of three feet, you create a buffer zone that helps to ensure the modem operates at optimal performance levels, providing a stable internet connection.

This distance is often considered a good standard based on typical interference sources found in residential environments. The choice of three feet balances the need for distance while still allowing for practical placement of equipment in a home setting without requiring excessive spacing that could be inconvenient.
