Purchasing a Modem for Xfinity – Applicable Factors

Before you think of buying the best modem for Xfinity, you must consider certain factors, and here are some of them:

#1) DOCSIS: DOCSIS is the telecommunications standard cable modem that is used for delivering data to your home. You will get two versions nowadays, such as DOCSIS 3.0 or DOCSIS 3.1. It is seen that DOCSIS 3.0. is cheaper and will provide basic service. DOCSIS 3.1. is the best technology for Xfinity. It is faster, future-proof, and offers lower latency.

#2) Speed: Speed is significant, and you must check for a modem that will offer you better internet speed. Not having proper internet speed will cause you to face lagging issues. You must check with the internet plan you are getting to see what maximum speed the chosen modem will give you.

#3) Ethernet Ports: A standard Ethernet port will support around 940 Mbps, and newer ones will support a speed of around 2500 Mbps. I would suggest you get a modem that offers a 2.5 Gigabit port so that you get the best performance at an affordable range.

#4) Home Size: Talking about modems, you need to check out the home’s size before you buy one. See whether your home needs more or less Wi-Fi coverage. Hence, it is better to see the modem or router that offers a better signal. You must have a strong network connection to reach all over your house.

If you have a larger home, then go for a better router, and if you have a smaller house, then you must opt for cheaper ones.

#5) Xfinity Voice: You must look for a modem that supports Voice Over Internet Protocol or VOIP if you have Xfinity Voice. That is because you will require a phone jack so you can connect the modem to your mobile phone. You will need to look for the Xfinity modem upgrade options for the firmware.

How we Selected these Products

While selecting the best modems for Xfinity, we had to keep certain parameters in mind:

• Speed: The first important factor which we had to consider is about having the right speed. A suitable speed will allow you to easily surf the internet with no lagging options.
• Channel Bonding: Having enough upstream and downstream channels will help you get the right results. A good channel bonding option with 32 downstream and 8 upstream will allow you to connect with more devices and hubs for faster streaming.
• Ethernet Ports and Connectivity Technology: The connectivity option for any modem will allow you to get connected to a router or directly to your device. It is thus very significant that you look at all Ethernet plug-in options or even other connectivity sources.
• DOCSIS Type: The DOCSIS type of the modem was slow to take into consideration. A minimum of DOCSIS 3.0 or DOCSIS 3.1 was kept to move ahead.

Cable Modems vs. DSL Modems

DSL modem will make use of the phone line to deliver internet service. On the other hand, a cable modem will use coaxial cable, something like cable wires, to offer internet service.

Here are the key differences between Cable Modems and DSL Modems:

• Speed: Talking about speed, cable modems will offer you faster speed than DSL ones. If you want to download a lot of content or do video streaming regularly, then you will need to have internet plans offering higher speeds.
• Availability: Cable modems are widely available, and there are some areas that offer only one ISP. While DSL is highly available across the U.S., availability might vary by location.
• Price: Keep in mind, the price of DSL modems will be cheaper than the cable modem plans. However, the pricing might vary depending on your location and the speed of the plan that you are opting for.

You must now pick up the modem as per your choice and basic needs.
