CM500 Slow download speed
I have the Xfinity 400 Mbps package and when I connect my computer directly to the modem, I'm only getting between 60-90 Mbps download speed. I called Xfinity customer service last night and they checked everything, ran some tests and said the problem isn't on their end and that I need to contact the maker of the modem. So, here I am.

What wired device do you have connected to the CM modem that your speed testing with?
What is the mfr and model# of the ethernet adapter in your PC?
What speed testing apps are you testing with?
Try a different wired PC to compare?
I'm using my laptop. It's a HP 17-x114dx.
I don't know what my ethernet adapter is. Not sure how to find that out.
I used the speed test on the Xfinity website and the speedtest.net.
I can try my wife's laptop and see if it's any different.
Look at the network properties in Windows for the brand and model of the adapter used on the wifi and ethernet adapter. It maybe Intel. Ensure the drivers for these are up to date.
