Reduce interference on a wireless network

The following tips can reduce interference in a wireless network:

Keep the wireless devices away from large metal objects, such as filing cabinets, and other
electromagnetic devices, such as microwaves and cordless telephones. These objects can disrupt
radio signals.

Keep the wireless devices away from large masonry structures and other building structures. These

objects can absorb radio waves and lower signal strength.

Position the wireless router in a central location in line of sight with the wireless printers on the
network.
