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.
If still appears even if you have tried the above, finish the measurement, then restart the IJ Network Tool to start
over the measurement.
