Monitoring Wireless Network Status
Make sure that there is no barrier or obstacle between the wireless router and the machine. Wireless communication between different rooms or floors is generally poor. 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.
Check3  Make sure that there is no source of interference in your vicinity.
If a device (e.g. microwave oven) using the same frequency bandwidth as the wireless station is placed nearby, the device may cause interference. Place the wireless station as far away from the interference source as
possible.
