Orbi drops Internet Connection

Thanks for all your suggestions.  The date was wrong on my system as well but changing it didn't impact the issue of dropping the connection. I have quite a lot using my network as in my heating and A/C system, surveillance and alarm, lights, TIVO networking, etc.  My Orbi system worked beautifully initially after I bought it and got the base station and satellite spacing correct.  Then at some point, I assume when the firmware auto-updated, things went badly with dropping the Internet connection but ONLY when I have multiple users at my home.  After updating to V2.0.0.74 I instantly lost connectivity on everything and manually went back a few releases.  Then I powered every device on my network down, updated the Orbi to V2.0.0.74 again and brought each device up individually.  So far I am stable and reliable when I'm alone using my network but this weekend will be the real test when my kids come over.  I will say the Netgear support staff have been VERY proactive in their efforts to help me.  I'm knocking on wood myslef here so hopefully all goes well.
