Tablo 4th Gen Screen Freeze Ups

I got the fourth-generation Tablo and successfully set it up. However, when watching any of the channels, the screen constantly freezes up for a second, kind of like it’s buffering. I have a strong signal from my antenna, and I have a three-year old, $300 wi-fi gaming router. Both the 2.4 and 5.8 lights are on. Do I need to make adjustments to the router, or is it something else? Thoughts?

Do you have the ability to wire it temporarily to try to rule out it being a WiFi issue?

Thanks for the suggestion. My cord does not reach that far. I called customer support and found out that the Tablo does not support the Chromebox, which is what I am using. I was told that they may support it in a couple of months.

I returned the Tablo.
