"No response frame" question

I am getting the “no response frame” for all of my devices and am at a loss of what to do.
This morning the MCV support team helped me get my VistaCam PT to work properly by doing a firmware update. It is after this update that things got buggy.
I have run the Repair/Heal function a few times and still no luck.
Any advice?
2 disclaimers:

  1. I am not an “advanced user”
  2. This unit is at a house I am not currently at, so I can’t physically touch anything.

Why not contact MCV support? Especially if this issue started after they made a change, I’d call them.

Fair point. I was hoping it was something simple, versus getting in the support queue again.
