The metal, concrete, or timber including the metallic material, mud wall, or insulator may interrupt a wireless communication. If the machine cannot communicate with the computer over a wireless LAN for the wall material, place the machine and the computer in the same room or floor. • Check 3: When using wireless LAN, make sure that there is no source of interference in your vicinity. Since a device such as a microwave oven uses the same frequency bandwidth, it may cause interference. Place the wireless devices as far away from the source of interference as possible.
