Not getting advertised speed
I signed up for the 1200 mbps plan but I am not receiving anything close to that speed. My speed fluctuates from 200 mbps to around 400 mbps. I have tried all of the recommended tips for increasing speed and nothing works. I also tried to adjust the settings on my my Xfinity Gateway, but most options are grayed out. I also cannot find a phone number or email address to contact customer support, so I am posting this in the hope that someone from Xfinity will contact me to help resolve this issue.

Is this with a WiFi connection ? If so, for a test, does a computer / device that is hardwired directly to the gateway device with an ethernet cable have the same problem ?

Sorry for the delayed response. Yes, I was referring to my wifi speed. I know I can’t expect full speed through wifi, but my laptop is just a few feet away from the Xfinity gateway and I should be getting more than 200 Mbps.
Testing the speed through a direct ethernet connection is a great idea. My laptop does not have an ethernet port, so I bought a usb-ethernet adapter to test the speed using a direct ethernet connection from the gateway to my laptop. I’ll post the results tonight. In the meantime, my wifi speed is even lower than it was yesterday, hovering around 200 Mbps.

So I finally was able to test my speed though a direct ethernet connection. It ranged from 830 to 930 mbps. Fast, but not the promised 1200 mbps. Normally I would not quibble over this speed, but it is likely to be a factor contributing to my slow wifi speed -- which is significantly below 50% of the speed I should be getting just three feet away from the Gateway. I have searched the Xfinity site for a technical support number but could not find one, which is adding to my frustration. The automated chat function is basically useless and I feel completely stuck with no ability to talk to a company representative about this problem.
It is also frustrating because I cannot make any meaningful changes to my wifi settings, like change the wifi channel (I live in an apartment building and something as simple as changing the channel could make a difference). I am considering getting my own modem just so I have the ability to tweak the wifi settings.
Does anyone know how to reach technical support so I can try to sort this out? Any assistance would be greatly appreciated.

There are other options. Google for WiFi repeaters / range extenders, WiFi mesh systems / pods, powerline ethernet adapters, MoCA adapters. Good luck !

Same issue here. Upgraded from 100 mbps to 300 mbps. When i had the 100, my internet speed test was around 125. Now with the 300, only get around 250.
