Miserable Setup Experience. Please help!
I have the Main Deco connected to the modem. It is solid green and working well.
Wifi signal has been disabled on the modem. DMZ+ set up on the modem.
I have 5 other sub Decos in the house on three different floors. They all will go online green for a while (day 1) and then flash red. All of them flashing red, disconnected after a day or so.
Here's what I've tried:
I factory reset everything, delte the network, and start over.
I have rebooted and restarted everything 1000x.
I have tried different ethernet cables, different ports on the modem.
I have brought satellite units (almost all of them) to test functionality right next to Main Deco. No dice.
If the Main Deco is working 100% of the time, and initially the sub-units are working (when I start over fresh) and then they all start blinking red...what could be happening? All disconnected. I am suspecting it's some issue with the setup of my Modem. AT&T Pace 5268AC. It makes no sense to me. I'm about to jump off a roof, I can't spend another day on trying to fix this but I don't want to return it and start over with another one.
I contacted customer service/support, was on for an hour plus, the lady could not figure out what was going on and elevated my request. She said someone would contact me. It's been 4 days and no contact.
