the router with a wired Ethernet connection when you want to make configuration changes.

Guidelines for reducing interference on a wireless network
The following tips will help reduce the chances for 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, as these objects can
disrupt radio signals.
• Keep the wireless devices away from large masonry structures and other building structures
as these objects can absorb radio waves and lower signal strength.
• Position the access point or wireless router in a central location in line of sight with the
wireless devices on the network.
• Keep all wireless devices on the network within range of one another.
