Xfinity Gigabit speeds

I tested four modems to see what speeds I can get with Xfinity Gigabit (model DLmbs/ULmbs): CM1000 950/46CM700 720/6CM600 720/6CM500 560/6 with or more that Xfinity offers 100, 200, 300, 600, 1000 in my region. So for gigabit you clearly need a CM1000 as it is DOCSIS 3.1 and xfinity has gigabit optimized for DOCSIS 3.1 and the boot process is also optimized for DOCSIS 3.1. If you have a data plan of 600Mbps or less even the CM500 will suffice as you will only see a maximum of 95% of your data plan, this also assumes you are not overly concerned with UL.

Pros
  • Easy to use
Cons
  • High price
