What Is Important Before Buying A Perfect Cable Modem :

First thing first, know about your internet service provider and the speed you are getting. After that make a comparison yourself which cable modem best suits you. For that purpose, a number of factors should be kept in mind. As discussed earlier some major key factors are elaborated below:

Docsis Protocols:

The maximum speed that a modem can deliver depends highly on DOCSIS (Data Over Cable Service Interface Specification) protocol that is fundamentally the standard by which all cable modems provide internet access over cable. DOCSIS 3.0 is the most widely used standard these days, it can offer speeds up to 1Gbps. The most recent development is DOCSIS 3.1 standard, which skillfully provides a massive speed of up to 10Gbps. You don’t need to get the latest standards as they are highly expensive.

Upload And Download Speeds:

While purchasing a modem every single factor has its impacts but like DOCSIS protocols, download and upload speeds play a major role in the performance of the modem. However, these speeds completely depend upon the number of downstream and upstream channels provided in the machine.

So what download speed you prefer from your modem? Of course the maximum it is the better it is. But, it completely relies on the speed you are getting from your ISP. For example, if you are purchasing a modem handling 600Mbps downloading speed, you must be subscribed to the 600Mbps speed or higher from your ISP. Then you might be able to get the desired results.

Cable internet speed in the USA is gradually increasing as ISPs are going to roll out Gigabit internet speed plans. That’s why you must buy a modem that has at least a 1Gbps download speed (if you can afford). That means you’ll be ready for faster internet speeds once it’s in the market shortly.

No. Of channels for speed

As discussed earlier the download and upload speeds primarily build upon number of channels equipped in the modem. Hence more number of channels means more speed you get. However please don’t forget that the greater the number of channels the greater is the price. So be specific.

Compatibility With Your Isp

Here is a piece of advice, don’t go for panic buying. If your old modem is dying and purchasing a new one is the only solution, calm down. Confirm with your ISP that the modem you are interested in will work for the internet plan you are ready to pay for.

Regrettably, some modems are not supported by some ISPs. So it always helps to first confirm from your ISP through its list of compatible modems or through contacting the customer service centre.

Price To Features Ratio

The price of the modem is that factor; most of you are better familiar with it. Different brands furnish their devices with different features and characteristics. You should consider a modem that provides a balanced price to features ratio.

You don’t have to get the cheapest modem in terms of price. Instead, go for the device which pays for itself. Also, make some comparisons with different brands. For a better price, you can also wait for discounts some retailers offer on certain occasions.

Reliability As Compared To Other Modems:

Cable modems are electronic devices as you know. That’s mean they have a limited lifespan like other electronic products. So make proper research for the best reliable cable modem that can serve you for a long duration.

For this purpose go through some of the customers reviews online for the product you are planning to buy. Also compare different models of different brands online and choose the best modem.

Warranty Period:

Warranty is another focal point you must consider before buying a modem. This is a type of security form the company that makes sure your investment is safe for a certain period. These warranties cover repairing or replacement of the product during the warranty period.

Usually, different companies offer different warranty period on their modems typically ranging between 1-2 years. Of course, the longer the warranty period is the better it is.

Built-In Wireless Router Or Just Modem:

This is a confusing matter to think for a few of you. Some cable modems are equipped with a built-in Wi-Fi router usually referred to as Combo Router or Router Modem Combo while others come alone. Using a Modem Router combo means hitting two targets with one arrow.

Buying a combo device is too expensive than just modem but on the brighter side, it saves you space and money being spent on a separate wireless router.

Easy To Use

Of course, every cable modem user wants a stable and fast internet connection with very simple and easy handling. It should also be easy to use with fast installation and plug and play connections. No one wants to call service center time and again for help on installation and setup. So a decent cable modem is always easy to install and use.

Design & Size Of The Modem: Must Look Attractive

As you know, cable modems are all about fast speed internet. But sometimes design and size of the device has an impact on your surrounding and it has to be figured out. Compact and slim designs look beautiful and can easily adjust in small space. It is also very nice to have a cable modem that can provide complete information about network status with indicator lights.

The design of the modem also helps in the passage of enough air to cool it down in many situations, which ultimately increases the working capacity. So, maybe the design of the modem comes after the performance and speed but that doesn’t mean you should ignore it.

Cyber Security: It’s Important:

Cable Haunt is a new critical vulnerability found in various cable modems. The remote attackers execute frivolous code on your modem; indirectly through an endpoint on the device ultimately intercepting private messages, redirecting traffic, or participating in botnets. Make sure a software patch is available to resolve this issue before buying a perfect cable modem for you.

Cyber attacks and denial of service attacks are also being common these days. While looking for a new modem you should also probe about all of its security features.

Ethernet Ports For Faster Connections

Connecting more than one device on your network through wire requires Ethernet ports. You might want multiple Ethernet ports on your modem but contrary to this, most of them in the market have just 1 port on them. You can connect your computer or a Wi-Fi router for more wireless connections via Ethernet port.

Few modems have 2 or 4 Ethernet ports with them but they are mostly expensive models. So go with your needs.

Brands To Consider

Last but not least, the choice of the brand solely depends on you. There are so many companies in the race for manufacturing the top best cable modems. But few companies have made valuable repute in the field of networking equipment along with their other achievements. These brands include Netgear, Motorola, TP-Link, Arris, etc…
