3. Check3 Make sure that the machine is not placed far away from the access point.

   The access point is located indoors within the effective range for wireless communication. Locate the machine within 164 ft. / 50 m from the access point.

4. Check4 Make sure that there is no obstruction.

   Wireless communication between different rooms or floors is generally poor. Adjust the location of the devices.

5. Check5 Make sure that there is no source of radio wave 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.

6. Check6 Make sure that the network settings of the computer are correct.

   For the procedures to connect a network device to the computer and set them up, refer to the instruction manual of your network device or contact its manufacturer.
