Buyer’s Guide

From the dawn of the internet, there has been a surging increase to access the near-infinite knowledge stored in this virtual library. The cost of maintaining continuous access is usually astronomical in the long run. This sudden need brought forth the introduction of devices such as Modems and Routers that allow you to access the internet from your systems at your convenience. Various factors need to be thoroughly checked if you are willing to buy a Modem or a Router, some of which are explained below. Once you grasp the basics, it’s pretty easy to get a gist of your actual needs and select the perfect device that suits them. Please keep on reading to refresh your knowledge on these devices.

1. Speed

With the growing trend, faster connections are readily available throughout the market as most network users hate slow network speeds. Choosing the best Modem also corresponds to the total uplink and downlink speeds it can support. One of the best available Modems is the ones that provide a link speed of 1 Gbps. Keep a note of your network provider’s highest speed limit too, since using a 1 Gbps high-speed modem for a 100 Mbps network connection will still cap your speed at 100 Mbps. Also, the 1 Gbps speed highlighted by the sellers only refers to the Downlink speed. The upload speed commonly peaks at about one-quarter of the download speed.

2. Channels

The number of available channels also determines how fast the modem is going to be. For example, in a 32 x 8 Channel modem, the total downlink channels are 32 and the uplink channels are 8. This is because most users tend to download data more than upload some. There are a few high-end systems that provide the same number of channels for upload and download but the applications of such systems are best in scientific research. For ordinary use, try to get at least a 16 downstream channel modem since it can tend to most networking needs of the current trend.

3. Compatibility

The next thing to be considered is the ISP compatibility. Most of the big shots in the Modem market provide products that support nearly all ISPs that exist, but some are limited in their scope as well. It’s always best to check whether the ISP you have is compatible with the Modem you are willing to buy. The best way is to just Google your ISP compatible modems or try calling your ISP to clarify the same.

4. DOCSIS Protocols

‘Data Over Cable Service Interface Specification’, commonly known as DOCSIS, denotes that your modem can provide broadband internet access through Coaxial cables. There are 2 versions available. The DOCSIS 3.0 is cheaper and is thus inevitably slower than the other variant. But, since most ISPs cap at around 100Mbps, DOCSIS 3.0 is enough to match the speed. If your ISP supports 1Gbps data transfer speeds, then DOCSIS 3.1 is the only way to go since it can support high-speed networks without any lag. This consequently makes it costlier than its counterpart by nearly twice to thrice its rate.

5. Design and Security

As far as design goes, there are only two options. You can either go for a Standalone design where the Modem and Router are obtained separately or you can opt for a paired device. Paired devices are usually the better option for novice buyers since there is a higher level of compatibility between the Modem and the Router. For those who are experienced, they can pick those that meet their exact needs as well. In terms of Security, Routers usually provide the means to restrict access based on the user’s preferences while Modems don’t have any security systems installed in them. The best way is to always check with your ISP, to confirm that your modem is secure at all times.


1. What is the advantage of a modem and router combo?

A modem router combo is much more efficient than an individual modem or router. It will save much space as it performs the functions of two devices in a single device. A combo will need fewer numbers of wires and cables. It can connect both wired devices and wireless WiFi devices. It also takes a simple process to set this up, saving your time. 

2. How is DOCSIS 3.0 protocol different from DOCSIS 2.0, 1.0?

DOCSIS 3.0 protocol is the internet standard that is a much-updated version of DOCSIS 1.0 or 2.0. DOCSIS 3.0 will provide high-speed internet connection than its predecessors. There is also DOCSIS 3.1 technology in modems and routers. If you prefer advanced technology for ultra-fast internet, you can opt for 3.1. DOCSIS 3.0 will support download internet speed up to 1 Gbps. 

3. What are the security features to look for in a modem or router?

Modems and routers are vulnerable to hacking over cables and by malicious sites. You cannot completely secure your device 100% but can look out for basic security features for optimum network protection. Features such as parental control options, WPA / WPA2 wireless encryption are some of the security features provided by the modem or router brands. You can contact your ISP to keep you updated on the internet security over the line. 

4. Why is ISP compatibility so important?

Your modem compatibility with your internet service provider will determine its working and speed. Modems usually come with a list of ISPs that it supports. You can either look at this list through modem websites or research on your own. You can also contact your internet service provider to gather the compatibility details.  

5. How to set up a modem at home?

You should plug in one end of the Ethernet or network cable to the modem and plug in the other end to your computer or any other device you want to connect. You can switch ON the power switch if there is one in the modem. Now, open your internet browser and enter the IP address of the modem to get access.  

The Optimum approved routers and modems listed above are of reliable quality and high-speed performance. Most of the models support internet speed more than 500 Mbps to provide you excellent browsing experience. Choosing the right modem or router for your home can be tricky, especially when there are many choices. You should sort out the number of devices you are going to use and select the device accordingly. Try not to skip crucial factors such as DOCSIS protocol, number of channels/ports, internet speed before you place your order.
