If you're referring to the MiFi indicator when first syncing the outdoor array with the display console, you'll need an Android device (like your phone or tablet) and the AWNET Console Configuration app from the Google Play Store installed. Mac users have a similar option for their i-devices. You might also want to read the users manual as it explains the procedure fairly well.
The Wifi icon should be showing solid at all other times; i.e., not blinking, so long as there is a connection with your local wifi; AND, your display console is powered using the AC adapter.
