I have xfinity 1.2gb plan and was looking to update to some newer or better cable modem as my old one is not doing that great. My download stream light is blinking (sec. led light from top to btm) and from my research is time for a new modem. I want to take advantage of the 1.2gb speed on my pc. (Had this from 2018)

I have a Netgear nighthawk cm1100 right now.

Thanks for your time.

***Update: Just ordered a Netgear CM3000 .
