Random stuttering

My FireTV stick (4k) experiences random stutters with my Tablo. If I pause the recording it clears up, but only for a few seconds. So I have to restart the FireTV and then it seems to clear up (until the next time, again, it’s random). Is this common with FireTV’s & Tablo? I’ve played with the recording/live tv settings but it doesn’t seem to affect anything other than quality, of course.

I had lip sync issues with my RokuTV before, so that’s why I switched to FireTV.

Wireless signal is strong so I don’t think that’s an issue (Google Wifi), but I can’t ‘choose’ 2.4 vs. 5, Google does that automatically.
