Ok now I am frustrated with streaming

Help me out here please. I was really enjoying getting into streaming. Just purchased a Node 2i 2 weeks ago and have been enjoying it. Testing Tidal and Qobuz, leaning toward Qobuz. I was testing both wifi and ethernet connection. I seemed to pick up some noise and distortion on what I thought was the ethernet so I have been listening on wifi. I really enjoy finding new music on the streaming service. Tonight I was enjoying Sierra Hull because I listen to a lot of Alison Krauss. I was listening to Sierra Hull's new 25 Trips album and got to track 7 Escape and I heard a bunch of static/distortion, almost like a blown tube, except I have solid state equipment. I switched to Tidal to see if it was a problem with the Qobuz stream and same thing. Hooked up my MacBook pro to rule out a problem with the Node 2i, same thing. Now I am listening to Clapton's Unplugged and I hear the same thing. Is it my internet? I have a brand new modem, a Motorola MB7621, and a brand new Asus AC3100 router. I did a speed test and we are getting 237 mbps. My daughter was watching Netflix on a TV upstairs at the time, when she was finished I did a reboot of the cable modem and reboot of the Node 2i and then it was fine after that. I listened for about an hour after that. Is it my internet speed? Do I need to call Comcast/xfinity and up my speed package? Is it something else? Its getting frustrating and its not supposed to be like that, I am at the point where I may just send the Node back on the return policy and stick with CD's.
