Cable Modem Router (Combo) Buying Guide

When you go for a cable internet connection the service provider will often tell you that with a small rental you can have your own modem also and you simply agree with it because you need to go online. But before you rent one just do some research and you will find many manufacturers offering cable modem router combo at an affordable price and the best part is these are quite durable and helpful and easy to control your internet usage. Compared to giving rental every month for gods how long, buying your own cable modem router always a good deal. Basically renting you a modem is a company policy to squeeze out money from you.

There are also some other factors important enough in a rental you must consider. One of these is the quality of a modem. Well, whenever you’re going for the rental you do not have your choice. You have to compromise with the modem the service provider will set up. Now this one cannot be efficient enough to fully utilize the speed of your internet connection. So you have to compromise with a lower speed.

Also, a rental modem can never have factory settings. It is a second-hand item so probably the security settings of the modem are preinstalled. So you cannot customize it to secure your privacy. So anyone near your house can eavesdrop your activity through the modem router and leech off the internet connection of yours. So, it is good to buy a brand new cable modem router (combo) for your home internet network.

Important things to consider while buying a cable modem router (combo)

Whenever you’re going to think of a home internet network, it is clear that you’re going to buy your own modem without depending on the service provider. Now before you buy a new cable modem router there are certain things you need to consider. These parameters are important because without having an idea about them you cannot get the full outcome of an advanced cable modem router.

Contact your service provider prior to buying a modem

Though almost any modem can work on the broadband internet connection still there are some exceptions too. Unlike a Motorola Surfboard SB6141 which can work with any major service provider modems like Verizon FiOS cannot do so. The major service providers have a list of compatible modems listed on their websites. It is good to contact the customer support section of the provider and confirm it. And if anyhow your modem is not working then some minor setting changes are required to fix it. The customer service executive will also tell you about when you call them.

Most Speed of the modem is important

The standard cable operator uses for information exchange through wires is DOCSIS. The different variations of DOCSIS are 1.x, 2.x, 3.x. so it is better you go for a modem compatible with DOCSIS 3.x or higher compatible. A middle or lower range modem will not utilize the speed of your connection fully. Generally, a DOCSIS 3.x modem offers a download speed of 340 Mbps and 130 Mbps of uploading speed. Higher-end modems give higher speed. Most of the modems have four to eight “down” channel and four “up” channel. A DOCSIS 3.x gives 43 Mbps in each channel which supports the speed measurement of the overall modem. Now there are sixteen channel modems that are also available in the market which has a download speed of 688 Mbps.

However, the speed of the modem can never boost the speed of the overall internet connection. If you have a 100Mbps internet channel then it won’t be upgraded to 300 Mbps as you’re using a DOCSIS 3.x modem with 340 Mbps speed. It will stay the same. So before you decide to buy a modem you have to have knowledge about the speed of internet connection you’re using and the compatibility of the modem with it. Otherwise, you cannot get the fullest of both the internet connection and the modem.

Ethernet port speed is also an important factor

Even if you have a high-speed internet connection with a high-end modem still your router will never give you the best speed in this setting due to the slow Ethernet port connection. The internet signal has to travel through the cables of the service provider to your modem then to the router through the Ethernet cable and through the air to your laptop or mobile. In between this route the Ethernet cable can be problematic. As there can be many choke points in the Ethernet cable.

Also the interruptions due to the wall, door and other appliances you cannot get the fullest of your internet connection. You must upgrade to the latest standards of Ethernet port to get the fullest output. But if you go for a modem router that supports internet speed in the gigabyte range then slow Ethernet port will not be a very big deal. But still, it is way too expensive for simple home use purposes. Cable modem routers with gigabyte range speed are best for professional gamers.

It should be your decision whether you need a cable modem router or not

While searching for the best answer for your home internet network, you will come across a variety of options. Like the combinational modem routers which serve all purposes in a single box. This means fewer wires and less complexity and fewer space adjustments. But it is not recommended always as this will simply limit your resilience. Now if you like to upgrade your router or the modem keep other parts the same then also you need to replace the total set up as it is compact.

There are many reasons you can have not to change a combo pack but there are also many reasons you need to change or upgrade the router or the modem. Like you need to upgrade the speed to stream high definition videos and play more games that require the high speed. Now the speed of internet connection cannot be increased but changing the router you can get the best outcome of the internet speed.
