Well, basically I only had to add the second repeater for remote access to my NVR. I need the 1st repeater to grab the signal and rebroadcast so that I have a signal throughout the house.
No, I do not need it connected it is more of a convenience. The thing is it was working great until I upgraded my POE switch and changed the wire config. Funny thing is after I changed the wire config back to have the NVR directly connected to the POE switch it dropped one camera once real quick and hasn't done it since. I'm going to leave it this way and watch it over the next couple of days.
