NETGEAR CM2000 DOCSIS 3.1 Modem Reviews

​The NETGEAR Nighthawk CM2000 is one of the latest modems released by Netgear under the Nighthawk lineup. The CM2000 can support speeds up to 2.5 Gbps, which really future-proofs this modem. It is compatible with most cable companies including Comcast XFINITY residential and business.


NETGEAR CM2000 Overviews

NETGEAR CM2000 is a new Cable Modem with AC1900 WiFi Router. It was one of the first to launch the DOCSIS 3.1 modem and basically doubles your internet speed. The DOCSIS 3.1 specifications support up to 10 Gbps downstream and up to 1 Gbps upstream network speeds, which means you can get over 300 Mbps per channel (a typical 8×4 modem offers around 100Mbps). If you like blazing fast internet then this is for you!

NETGEAR CM2000 Reviews

Design

The CM2000 switched to a new design and now has an external power adapter. I’m not happy about this change as it makes the modem bulky and it can’t be wall-mounted like most other modems. On the positive side, I love that the stand is large enough to allow me to stack two routers on top of it (the TP-Link Archer C7 & Asus RT-AC66U) without blocking any ports or interfering with airflow.

Smoke

I’ve never smelled melting plastic, but after only five minutes of operation, I could smell electrical smoke coming from inside the modem and quickly turned it off. *Update: After further review, I believe the smell was coming from my laptop’s USB port. It’s an old laptop that I rarely use. I haven’t had any problems with it before, but now after the incident, it has started to randomly disconnect from external hard drives.

Performance

The CM2000 is a very basic modem, which means you cannot tweak any settings or change the wireless channel. From what I’ve read this doesn’t affect performance much as most modems are configured using software on your router. The CM2000 does have up to 1-gigabit ethernet port, unlike other “DOCSIS 3” modems that only have two 100 megabit ethernet ports & four separate 10/100 switch ports (TP-Link Archer C7).

Connectivity

This is where the CM2000 shines. I’m on a plan that receives nearly 300/300 speeds from my ISP, but the TP-Link Archer C7 couldn’t deliver those speeds to devices located more than 10 feet away from it. The CM2000 didn’t have this problem and all of my devices received high speeds throughout the house.

Conclusion

I really enjoy using the NETGEAR CM2000 as a modem because of its great performance, but I can’t stand having multiple devices with external power adapters plugged into a wall outlet. If you don’t mind leaving an extra plug free for powering the CM2000 then I highly recommend buying one of these modems instead of just renting one from your ISP.
