Just out of the blue..I have had no prior issues.. This morning I power up my bird and it does not find the signal.. The app gave me a firmware update status.. So I updated the firmware 1.6.0 and it confirmed update.. But still will not find signal.. it says "signal lost" every time I power up... It again told me firmware needs update : current version unknown new version 1.6.0 .. repeat steps several times and it still will not connect.. I swapped out sd card and power cable as precautionary measures and it made no difference... Any suggestions ?
