CM2000 modem connections
A newbie question, I recently installed a CM2000 modem to take advantage of xfinity 1.2 Gbps plan. I am only achieving 900Mbps when connecting the modem directly to my PC. My newbie question: Should ...

Yes, and the LED indicator will turn from white to blue. The limiting hardware will be the 2.5 Gbps port on the modem. so it would pass the 1.2Gbps from ISP to the router. I can then use lan aggregation from router to a PC dual port PCI card. In theory it should. Link Aggregation from Netgear may or may not play nice with Link Aggregation on whatever brand of network interface card you choose. I have the Nighthawk mobile application installed on a Samsung tablet. Connected to the router, the internal throughput test measures between the modem and the router. No computer connection needed.
not sure I want to go this route or just upgrade my router. Thanks again
I have to ask the question. What activity are you using your internet connection (modem, router, computer) for that comes close to saturating a 1 Gbps throughput. In real life, the only way your will be able to tell the difference between 940 Gbps and 1200 Gbps is with a throughput capacity test application.

My newbie question: Should the multigig led on the modem be blue if xfinity is sending 1.2 Gbps? I know I won't see 1,2 Gbps on my pc as the network adapter is 10/10/1000 Mbps.
My current router is a NightHawk x10 R9000. What router with a 2.5 multigig port would be recommended that is comparable? Is there any way to configure the R9000 to achieve better than the 1 Gbps?
Thanks for any help.
No, the multigig LED on the modem only shows blue when the output of your modem is connected to a device that can receive multigig throughput. As long as your R9000 is connected to your modem through the 1 Gbps WAN port, the modem multigig LED will remain white.
The R9000 also has an SFP WAN input rated at 10 Gbps. You can get an SFP/RJ45 adapter and a Cat 6a Ethernet cable to connect your R9000 to your CM2000. From Amazon https://a.co/d/iX5LOAG and https://a.co/d/4rGg5lV. They work fine together with the R9000
đ.
Regardless of what you do to soup up the input to your R9000 it is equipped with 1 Gbps LAN ports and in real life the most they can transfer out is around 940 Mbps.
See attached.

Thank you for your help. I am using Xfinity ISP. I got a promotional deal1(1yr free upgrade from 800Mbps) to the 1.2Gbps plan. IT is overprovisioned at around 1450Mbps. I I installed the CM2000 with 2.5 Gig port. I decided to add a 2.5 gig PCIe card to my PC, rather than attempting Link aggregation. So with out the router restriction to 1.0 Gbps, I am getting 1450Mbps download an 41Mbps up load, through the router, Nighthawk R9000, I get 900mps. So thinking if I upgrade my router I could get around 1300Mbps, and better WIFI. I know not significant differences in internet speed, but just playing around.
