Netgear CM1000 Key Specifications

Netgear has been one of the best home networking brands from decades. Their one of the best modem, the Netgear CM1000 is being advertised as the modem on the market delivering the highest speed. But how fast is it actually? And will the consumers actually gain any benefit from upgrading to this high-speed equipment? Or is it all just marketing?

In recent times, DOCSIS 3.0 was acknowledged as the latest kind of the protocol, supporting higher data speeds and IPV6. Later DOCSIS 3.1 has been implemented by ISPs of USA. This has a minor upgrade to the DOCSIS 3.0 standard, But providing crucial benefits on internet connections.

According to feedback from customers, this Netgear CM1000 modem worked great so far. They were getting internet speeds as per the new norms as they are supposed to be.

So, you do not need to rent a modem from your ISP and buy your own Gigabits modem to access lightning fast internet. When user have the 150mps download speed plan but surprisingly the modem’s download speed results clocking him at over 165mps(Wireless). It was tested on So the results are quite clear. He did not have any connectivity issues either since its registration.

With his original ISP modem, the speed was just par, however, after installing the CM1000 the speed had improved staggeringly. Even with an iPhone, the speed was impressive i.e 220-230 Mbps. Customers have been very impressed with how easy the setup was and how well it worked. However, a some of customers has also complained about not getting speed as specified. Maybe their ISP had some issues or they might have faced some connectivity issues, who knows?

So it is highly recommended that make sure that your system actually needs and handle such type of modem and the Gigabit speed it provides with. Last September, Comcast finally announced the latest DOCSIS 3.1 service. The advertised download speed is 1 Gbps, and 35 Mbps up. Most cable consumers are used to receiving speeds well below what’s advertised. But one can notice that Comcast is providing with a service that is technically capable of delivering 1.2Gbps and advertising it as 1Gbps. This is because there is and always will be some noise or cross chatter that reduces the actual bandwidth below the theoretical maximum.

Ports Comparison

Arris SB8200 Ports

It has 2 Gigabit ports for 2 separate networks (Global IP’s) and enables the user to utilize link aggregation. The dual LAN ports on the back are cool, but only useful if your ISP provider allows you to use the second one, sadly, Comcast Xfinity does not. While this particular modem is very easy to set up and gets working fast as well. Most people have purchased this because they needed two ports, both of them being gigabit and DOCSIS 3.1 means that they are set for future speed increases.

Netgear CM1000 ports

However the Netgear CM1000 bought has only one bright-yellow port, So there is always a risk of the Ethernet port failing, leaving you with no choice but to call the repair team or hiring a professional. Few customers also complained of the modem not giving continuous high-speed data as it has only 1 port. So customers of this particular often wish the unit had two gigabit LAN ports so they could run one to their router and the other to my OOMA phone box or switch for OOMA and Google Phone or any suitable equipment.

So, clearly Arris sb8200 has an advantages on ports.

Features Comparison

Arris SB8200 Features

This particular Arris modem supports IPv4 and IPv6 Internet browsing standards. Even though it has two working ports Cox Cable does not support activation of a 2nd Ethernet port, however, works smoothly on Comcast, dual Ethernet, after removing Bufferbloat issues. Rest it is compatible with most of the major cable providers in the US. It is absolutely perfect for 4K Ultra-HD Video Streaming and VR Gaming. Works easily on Comcast, dual Ethernet removed my Bufferbloat issues After upgrading old modem using DOCSIS 3.0, with 4 channels to SB8200. Speed should at least be doubled. No problems were found.

However, people complain that is very expensive and understandably so with such modern feature. Actually, people complain of it being way ahead of time. So by getting this particular modem you’ be absolutely future-proof.

Netgear CM1000 Features

This modem has 2 OFDM downstream & 2 OFDM upstream channels for DOCSIS 3.1 connections as well as it Works with XFINITY® from Comcast and supports fast web-based self-activation for XFINITY customers. Customers having Comcast, it’s super easy to set up. It would take less than ten minutes to set up your modem with your cable or PC. Those who have Comcast as their ISP there are instructions specifically how to set it up. Very convenient isn’t it? It has a full proof airflow design. No matter which way it is oriented, surrounding air will provide cooling either way. Remember, this modem is a lone but pivotal component in your home network.

If you upgrade to a high bandwidth modem and expect to get the data at exactly that speed through an outdated router, you’re definitely not going to get the performance you expect. So you may have to consider opting for an additional modem to help you push your bandwidth faster than you’ve ever thought possible.

If you checking for easy setup modem, netgear cm1000 will be winner. But I think setting up arris sb8200 would not that much of difficult.
