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 products on the
network.
