Upload speeds nowhere near what I'm paying for.

We just switched our plan over to a new one and I was assured that I would be getting 1000mbps down and 100mbps up. We are not getting those upload speeds at all, and they seem to be capped between 35-40mbps during the day, but in the afternoon, they randomly plummet to single digits and bounce all over the place wildly. My upload speeds become so unstable it's insane.

I've spoke to multiple chat agents, made a phone call, switched to my own equipment, switched back to the xfinity gateway, spoke to MORE chat agents that just keep telling me over and over again that they've fixed the problem, and it's STILL ongoing.

Yes, I've reset the router. Yes, I've fixed my firewall settings. Yes, I've tried the connection on another pc wired directly to the gateway and get the same results. I'm using a brand new ethernet cable, it's a cat6 that's rated for high speeds. I just activated the gateway hours ago and have been chatting with various people all day. Each one has said they would send a confirmation email and we have received none.

Just... help please lol
