How We Choose

There is a lot that we take into consideration before choosing and recommending products.

We always ensure that we are choosing the best possible products that feature good specifications for gaming. In addition to this, we aim to choose a range of both high end, and reasonably priced options to suit all budgets.

We always thoroughly test the products we recommend, to ensure that they are of a good quality, and perform as expected. When we tested these modems we checked the connectivity, the connection speeds, the max download speeds, and also their durability.

Our team of experts look into each product carefully, and research them in detail, while also taking into consideration the opinions of customers. All the modems featured will help to lower your internet payment costs, and are great for use when gaming.

Things To Consider

Before deciding to purchase a Docsis 3.1 modem, here are six different aspects that you will want to keep in mind when choosing.

Price

The first aspect to take into consideration is the cost. The cost of the modem is important, as you will want to choose an option that is within your budget. When it comes to Docsis 3.1 modems, they are not always the cheapest options.

However, when you take into consideration their overall specifications, and the quality of the modems, the cost is often justified. This is especially true when they help to improve your internet speeds and gameplay.

While they do come with an upfront cost, they will save you money in the long run, and you will make this money back. This is because by purchasing your own modem, you will not have to worry about renting a modem monthly from your internet service provider. This requirement will then be removed, and you can choose a less expensive contract deal.

Internet Speed

The second aspect you will want to consider is the internet speed. When changing modems, the last thing you will want to happen is your internet speed declining. All the options we have chosen will help to increase your internet speed, especially when you connect via the Ethernet port.

The great advantage of choosing a Docsis 3.1 modem is that it stops the capping or throttling of your internet speed to very low amounts. The upstream caps for these modems are 2 Gbps, and downstream its 10Gbps.

This means that even if you are running on the lowest internet speeds, it will still be faster than an older modem, which can be as slow as 100Mbps. To receive the highest speeds, you will need to have 2 IP addresses registered, which is worth keeping in mind.

Compatibility

When choosing a new modem, you will need to take into consideration its compatibility. The last thing you want to happen is to connect the modem up to your internet, only for it to not be compatible.

Thankfully, all the options we have featured are compatible with the majority of ISPs, such as Xfinity, Spectrum, and Cox. However, they do have some limitations when it comes to fiber optic services, so you will need to take this into consideration.

Wi-Fi

You will also need to check the compatibility of the Wi-Fi router and the modem. While all of these options are compatible with the majority, if not all, of routers, other modems may not be.

The majority of routers will need to have a Wi-Fi router connected, however, some will have the Wi-Fi built into the modem itself. While the Ethernet port provides the fastest internet connection, if you are connecting other devices in addition to a gaming PC, such as smartphones, Wi-Fi is useful to have.

Durability

You will want to ensure that the modem you are purchasing is made from good quality materials. You want it to be sturdy enough to not fall apart if it does get knocked over.

As it is an investment, you do not want to have to replace it after a year or two because it is damaged. In the same vein, many companies will offer a warranty on the modem. This will give you peace of mind should anything happen to it within this time.

Security

Last, but not least, you will want to take into consideration the security of the modem. Some modems have been vulnerable to attacks in the past, mainly because of the cable haunt software flaw.

You will want to carry out research to ensure that the modem is safe from this. However, you can potentially receive a software patch from your ISP if there are any security issues. This will help to prevent any breaches from occurring.
