Repeater XR – PICO Reset and Reload Instructions

Posted by A.J. Farmer on

The following instructions describe how to reset and reload the configuration for your PICO outdoor WiFi receiver.  You should follow this procedure if you are having the following symptoms when using your JEFA Tech Repeater XR:

  • You can see your repeater’s private WiFi network, but when attempting to connect to it, you may receive an error message such as “unable to obtain IP address”, “limited connectivity”, “Self Assigned IP” or “DHCP error”
    • NOTE, your repeater’s private WiFi network may be named “jefatech-repeater” or it may be a custom name that you have given your repeater

You should first verify that your PICO is properly connected and powered on:

  1. Verify the black cable from your PICO is plugged into the port marked POE on your indoor AIRGATEWAY unit
  2. Verify that the bottom two lights on the PICO are lit.  The bottom light indicates it is getting power.  It should be steady on.  The second light up indicates an Ethernet cable link to the indoor unit.  It should be on and it may flicker.  If you aren’t getting these lights, check your cable connection between the PICO (outdoor unit) and AIRGATEWAY (indoor unit).

After verifying the above, disconnect from and reconnect to your repeater’s private WiFi network.  If you are still experiencing the same symptoms, you should reload the configuration of your PICO :
