Buffering issues on live and recorded shows

Since updating to 2.2.6, I’ve had lots of random buffering during live and mostly recorded shows. It will last 1-3 seconds and occur every 2-5 minutes. I’m watching on a sling Android TV and a Nexus Player. Please help as this makes watching anything painful and I don’t want to lose the wife’s approval.

I get occasional buffering and my setting is 720p. I have a Roku3, everything hardwired (so that part matches what they found). I am not seeing this at a level that many others are at this point.
