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 wireless router away from such
sources.
• Check if the radio channel of the wireless router is close to that of other wireless routers
nearby.
If the radio channel of the wireless router is close to that of other wireless routers nearby, the
connection performance may become unstable. Be sure to use a radio channel that does not
interfere with other wireless routers.
• Check that the printer and the wireless router face each other.
Connection performance may depend on the orientations of the wireless devices. Replace the
wireless router 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 and restart the IJ
Network Tool to start over the measurement.
Note
• If any messages appear on Overall Network Performance:, move the machine and wireless
router as instructed on the screen to improve the performance.
