Have tried replacing the batteries in the third and still will not re-sync. No blue light comes on at all.

Alos, be sure to simply place the batteries in their slots - don't push them down. Let the battery door do the pushing.</P> Wed, 20 Dec 2017 21:49:01 GMT https://community.arlo.com/t5/Arlo/Can-t-sync-third-camera/m-p/1463205#M46361 jguerdat 2017-12-20T21:49:01Z
