Xbox Series X Internet Speeds

I’ve recently upgraded my internet package to 400mbps, however, I can't enjoy it while gaming. Every other device (phone/tablet/laptop) I've done speed tests on shows down speeds of ~400mbps EXCEPT my Series X. If I do the Xbox system speed test, or even use speedtest on the Edge browser, I get no more than ~200mbps down. That's quite a drop. Most of my devices are wireless, and I understand wired is always the way to go, but sheesh. Why would I be getting HALF of my possible max down speeds?

I've ensured every app is closed on my Series X, cleared my MAC Address, and even changed the DNS address. I'm out of solutions at this point.

Hello u/thoed_e and thank you for reaching out to us via our Forums. Having issues with any of your equipment while trying to game or just enjoy your services would be upsetting and frustrating. This is never something we want for you to experience from us. You have come to the correct place to help you with all your Comcast account needs. I know if I was having the same type of speed decrease I would be reaching out too. 

 

From everything I have read in your post it leads us to believe that this could be a device related concern. If all your devices were having the same speed changes I would be led to service related. Personally I have a few devices in my household that are not able to use the full speeds we pay for. For example on a 1 GB internet plan, the download speeds of the Xbox Series X averages between 200 Mbps and 320 Mbps. This is due to the limits of the Xbox not being able to use the full speeds being provided. Please let us know if you have any other questions about your Comcast account as we are always here and happy to help you!

@XfinityPeterB I have the 400mbps unlimited plan, my series x is directly plugged into the router, and it runs around 70 mbps 60% of the time and 8-15 mbps 40% of the time. Same as the other guy, other devices are getting full speed. This is an obvious throttle. This is horrible.  What a joke comcast.

I've seen Series X download speeds above 320mbps. For instance, when I take it to relatives' homes. Unfortunately for me, mine fluctuates SO much. I've topped out above 300mbps but will drop as low as 40mbps. I just don't understand it. I can't tell if it's the console throttling the speed or my gateway.

Thank you for that info @thoed_e. I can understand where this would be frustrating. Since you aren't having issues on other devices, this points to your Xbox. Is your Xbox hard wired to your modem with an ethernet cable, or are you connected via Wi-Fi?
