They know about it and are pushing a fix soon hopefully. So ends my day of mystery. https://twitter.com/viziosupport/status/1099794021373882368?s=21
I have a Vizio 55" D Series Smart TV purchased in 2014. I've used wifi connection through a Nighthawk router 2.4Ghz band and most recently a 1GB up/down FiOS router 2.4Gz band (for the last 7 months) for internet the entire time I've owned it without an issue. The TV is 6ft away from the current FiOS router.
In the last few days while connected via wifi, a "Network Disconnected" error screen has started randomly popping up every 30-45 minutes when NOT using an app, but just watching TV through the cable box. When it appears, the "Network Setup" button is highlighted but is not selectable. Only "Close App" is selectable. The idea that "Close App" is an option when no app was opened is the confusing part. I had changed no settings or connected any new input devices up to this point.
So at first I:
- Rebooted the router
- Reset the TV to factory defaults
- Turned "off" DHCP
- Turned back "on" DHCP
None of that worked, so I just decided to hard wire through ethernet, thinking that would take care of it. It did not.
So I reset the factory defaults one more time while the ethernet cable is plugged in just incase the wifi settings were still interfering somehow. The error message still showed up.
With the wired connection I'm getting about the same connection speed through the TV as when it was using wifi, 10-45mbps.
It appears that this only happens while on the FiOS cable box input with no apps open. If a Vizio App or my Roku input are being used there's no issues, I'm not getting any dropped connections during use, only when apps are not being used.
I'm at a loss. Logically, none of this makes any sense.
