Buying Guide For The Best DOCSIS 3.1 Modems?

To choose the best DOCSIS 3.1 modem, you should be able to tell the difference between different modems. To help you out, we have detailed the most important things that you must for in a DOCSIS 3.1 modem.

1. ISP Support

One of the most important things is ISP support. Before you get a modem home, you need to make sure that it is compatible with your ISP. Look for modems that are compatible with major ISPs like Spectrum, Cox, Xfinity, etc. You cannot use a modem that is not supported by your ISP.

2. Upload and Download Speed

Besides knowing the connection speed of your internet plan, you must also know the connection speed offered by your modem. It is important to know the upload and download speeds that you are getting from your modem. Remember, every modem offers different speeds. To enjoy fast internet speeds, you need a modem that offers the highest speed.

3. Multiple Ports

All modems are not the same. The number of ports offered by a modem will vary from model to model. We recommend you opt for a modem with four ports. The more ports a modem has, the more devices you can connect. Before buying a modem, check the number of ports it has.

4. Modem Router Combo

We would suggest you get a modem-router combo as it makes a better choice than buying the two devices separately. Purchasing a modem router combo will help you save money. Instead of spending money on two separate devices, you will pay for just one device.

5. Security

When choosing a modem you must look into the security features it has. A cable modem with a Broadcom chipset is considered the best. This is because it enhances the security of your network and also provides protection against DoS attacks. In case, you are purchasing a modem-router combo, look for devices that support WPA/WPA2 and WEP wireless security protocol. This comes in handy in preventing unauthorized access.

6. Warranty

You must also check the warranty of the modem before getting it home. Look for modems that have the longest warranty period. You will need some time to judge the performance of your modem. Most modem manufacturers offer a 1-year warranty. But you will also find modems that offer a 2 or 3-year warranty.

7. Cost

Last but not least; you should also consider the price of a modem. You might get tensed seeing the high costs of DOCSIS 3.1 modems in the market. But you don’t need to spend hundreds of dollars to get the best modem. Many reputable manufacturers offer modems within an affordable range. Just check the reviews of the modems before buying and you are good to go.

What to Choose: Modem or Modem-Router Combo?

When you purchase only a modem, you are faced with several problems. For example a shortage of ports. Most modems have only one or two ports in the back. Even though this is not a major problem, other things need to be taken into account.

Opting for a dedicated router is generally considered more advantageous. This is because dedicated routers are more advanced, and can offer up to the tri-band network. This feature is great for people with several devices.

If you opt for a separate modem and router, the biggest disadvantage is the cost. Since you are buying the devices separately, it will cost you more. Modem-router combo, on the other hand, is more affordable because you are paying for just one device. This is why we would suggest you opt for a modem-router combo. It will not only help you save money but also make your life easier.
