The circle of death?

I purchased a SPVR2-01-NA about a year and a half ago and it worked great for a year.currently having very bad playback issue. I call it the circle of death.

TABLO Model: SPVR2-01-NA
External Hard drive: Currently using Samsung 860 Pro 1TB SSD
Antenna: Antop AT-133 Indoor TV Antenna
Router: Linksys EA9500 Max-Stream AC5400 MU-Mimo GB Router
Playback Device - NVidia Shield and Roku 3

Programs seem to record fine. Upon playback, I either get a circle spinning or the video freezes and audio continues.
I can fast forward to get out of the freeze, but I can’t get it to play the frozen part.

Troubleshooting thus far:
Swapped Hard drives. Moved from an external Seagate SSD to the Samsung 860 Pro. Both were 1 TB
Swapped Routers. Originally on a Neatgear nighthawk. Moved to this Linksys
Ran antenna all the way to the attic - getting perfect signals on all big 4 stations

Any advice would be greatly appreciated.


Are you wired up?

if on wifi, are you bouncing back and forth between 2.4 and the 5.0?

Side note, how do you like the Antop?
