Most all works well.....except.....DJI Vision app on androin phone show no connection to drone.  App shows no telemetry.  App does show battery level of Range Extender.   Is this a bad WIFI module in the bird or something else?   Help me all you veterens.  Thanks

You might consider contacting DJI.  They have just recently begun repairing these P2V series Phantoms for free provided you haven't modded the bird.  

Will do.  Thanks for the tip!

I'm afraid that this issue can not be figured out remotely. Please kindly start a case and send it in from here: https://www.dji.com/support
