Modem Won't Go Above 100mbps

[rockncountry]

Hi all! This is the best forum I've found for answers to my tech questions! I have an Arris CM820 that is rated for 300 mbps. When hooked up to my 150 mbps connection I don't even reach 100 most of the time. The tech says that I need a new modem. It is a DOCSIS 3.0. He said that I need a DOCSIS 3.1. I'm confused. Please help. Thanks!

Maybe thats because it has Megabit ethernet ports and not gigabit ethernet ports so speed never goes above 100Mbps

Your ISP will post a list of approved modems for each level of service. You need to pick from that list.

if you are a real geek, investigate port speed and negotiation. If you are "I just wanna..." buy a new modem.
