Nighthawk C7000 random disconnects every day

So I waited for 24 hours and my router went off line again. The upstream light starts to blink, and we loose connection. Than sometimes my internet light blinks and we are out of connection again. So I called nertgear again and was on the phone with them while the tech was looking into it. My internet went down while he was helping us. He stated he will have his highest level techs call me at 4 on Thursday. But no one has called until now, it’s Friday. My internet is still down. Called XFINITY and they are showing no issues on their side. I am just about to throw the netgear router on the street and record it for YouTube, that’s how disappointed I am. I will be walking to Comcast to pick up their router soon. Do not buy Netgear. That’s just my experience.
