One of my outdoor camera stopped connecting but my other one still works.

I have 2 simple safe outdoor cameras.  They worked fine for about 6-8 months but a couple of weeks ago one of them would connect but it would never be able to display anything and stop trying giving me a link to trouble shooting.  I finally got to the point where I removed the device thinking I would just re-add it.  No dice.  The camera would blink (it says white but it looks more blue'ish but there is no error code for that).   The camera that is furthest from the router works just fine.  I have tried multiple time to get this device to re-add but it never does.
