Ring camera problems?

Have a ring spotlight camera and all of a sudden it started showing battery 3% and would not connect video.   Tried 2 additional batteries and problem persisted.   Purchased another ring  spotlight camera with new battery and same problem.  Called ring tech support and I did everything he said to try and it still did not work.  He said I received a faulty unit and to return it and try again.   Returned the unit and the third one will not connect either and occasionally it says streaming error.   I followed all the instructions + troubleshooting instructions exactly and problems continue.   Any suggestions on what the problem could be?   Could it be a wifi issue and not an actual problem with the ring itself since the same problem has happened 3x now with 2 of the rings being brand new?
