My 300mbps internet appears to be throttled to 100mbps

The internet works, the connections are stable but consistently around 110mbps.

@madeingouda Can you go into your router's interface and let me know what speeds it is reporting? Also, did you restart your modem after connecting different devices to it? Many times, routers will not update their settings between devices without a restart in between.

I’m just going off of what Xfinity is telling me on their website. The SB8200 is one of the models that came up when looking up my address and speed. The sb8200 is even listed as supporting 800mbps.

You are not going to get 100 up with that modem. An incompatible modem will also default to using a slower-speed bootfile for the download as well....

That makes very little sense. Then they need to put that on their website and not mislead customers into buying something incompatible and spend time on support calls and user forums. (edit: sorry - i didn't realize you were talking about just the upload speed)

Plot twist / update - after talking to a chat agent, I ordered a XFi Gateway to determine what was wrong with my connection. The day after we had an issue where my wife couldn't watch anything on the Xfinity app because it thought it wasn't on Xfinity home internet. This chat agent determined yesterday that my cable modem was not "activated". This sounds strange, as I definitely was on the XFinity connection with my WiFi?? I am unsure what was done but I am now getting 350mbps down and 25mbps up WITH THE ARRIS MODEM. This all seems to confirm my initial theory that my bandwidth was throttled on purpose until I complained about it, or upgraded to the XFi gateway.

@madeingouda thanks for taking the time to reach out. We're happy to hear the speeds have improved. Is there anything else we can help with today?

No worries ! And I couldn't agree more. They could / should have made things much more clear......
