3. Select Status on the View menu.

   The Status screen is displayed and you can check the printer status and connection performance.

   
   
    

   1. Signal Strength:
      Indicates the strength of the signal received by the printer, ranging from 0% to 100%.
       

   2. Link Quality:
      Indicates the signal quality excluding the noise while communicating, ranging from 0% to 100%.

      
       Important

      • If the indicated value is low, move your printer closer to the wireless network device.
         

4. If you measure connection performance in detail, click Advanced Measurement....
   The Connection Performance Measurement screen is displayed.
    

5. Click Next>.
   The measurement starts and the status displays. Measurement takes a few minutes.
    

   
    

6. Check status.
   When the measurement is complete, the status is displayed.
    

   
    

   When is displayed in Connection performance between the printer and the wireless router:, the printer can communicate with the wireless router. Otherwise, refer to displayed comments and the following to improve the status of communication link, and click Remeasurement.

   • Check that the printer and the wireless router are located within the wireless connectivity range with no obstacles between them.

   • Check if the distance between the printer and the wireless router 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 wireless router.

     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 wireless router.

     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.
    

7. Click Finish.
