6. Check the status.
When the measurement is complete, the status is displayed.
When is displayed in Connection Performance between the Printer and the Access Point:, the
printer can communicate with the access point. Otherwise, refer to displayed comments and the
following to improve the status of communication link, and click Remeasurement.
• Check that the printer and the access point are located within the wireless connectivity range with
no obstacles between them.
• Check if the distance between the printer and the access point is not too far.
If they are too far, move them closer together (within 164 ft./50 m).
• Check that there is no barrier or obstacle between the printer and the access point.
In general, connection performance decreases for communications through walls or between
different floors. Adjust the locations to avoid such situations.
• Check that there are no sources of radio interference near the printer and the access point.
The wireless connection may use the same frequency band as microwave ovens and other
sources of radio interference. Try to keep the printer and the access point away from such sources.
• Check if the radio channel of the access point is close to that of other access points nearby.
If the radio channel of the access point is close to that of other access points nearby, the
connection performance may become unstable. Be sure to use a radio channel that does not
interfere with other access points.
• Check that the printer and the access point face each other.
Connection performance may depend on the orientations of the wireless devices. Replace the
access point and the printer in another direction to achieve the best performance.
• Check whether other computers are not accessing the printer.
If appears in the result of the measurement, check whether other computers are not accessing
the printer.
