There are a number of considerations when choosing an Xfinity modems and routers.

To decide which type of broadband connection to get from Comcast, consider how much you use the Internet, what kind of content you stream, and whether you need high speeds. Then look at the different options available. You may be able to save money by buying a lower-speed plan than you would if you had unlimited usage.

If you want to buy a modem and/or a wireless access point (routers), you should consider them separately because they offer different features and benefits. For example, routers typically provide better coverage than modems.

Frequently Asked Questions

What features should you look for when buying a combo modem/routers?

When shopping for a modem router combination, check to see if it works with your current Internet Service Provider (ISP). Most of the models we've listed will work with most cable modems, but the Motorola M7711 will only work with Xfinity Voice and BroadBand services.

If you have a digital subscriber loop (DSL) or fibre service, the models on our lists won't be compatible, so this would mean that AT&T and Verzion DSL, fibre, or FiOS subscribers will be left out. You may be able to get a modem-router combination that works for your particular service, but there are some caveats. First off, not every modem-router combo will work with every type of service. Secondly, even if you're lucky enough to get one that works, you might not be able to use it because your provider doesn't support it. Lastly, even if they do support it, you might not be allowed to add it to your account because it could cause interference with other devices on your network. So, the best advice here is to check with your ISP before buying anything.

Modems vs Renting modems: What are the pros and cons?

While renting a modems may seem bester — you do not have to put down several hundreds of dollars to cover the costs at once — it can end up being costly in the long run. Comcast, for example, charges $14 per month rent, up from the previous price of $13. This implies that anybody who leases devices will be subjected to shifting market and economical situations. In two years, Comcast’s monthly rental charge will amount to $336 at current prices.

If you choose not to buy a modem from them, they may charge you an additional $5 per month for a router.

When shopping for a new router, consider what features you really need. Do you need a fast connection? Is speed important to you? Will you be streaming video or playing games online? What kind of security do you need? Are you concerned about aesthetics? How much space do you have in your living room? You can find routers that offer everything from basic internet connectivity to advanced gaming capabilities. Some come with built-in wireless access points so you can create a network without having to buy one separately. Others include multiple Ethernet ports so you can connect additional devices such as printers, TVs, and game consoles. And some allow you to customize the appearance of your device with skins that change the color scheme and add special effects.

If you're not too technical, renting a modem from an internet provider will allow you to get started quickly. Once you feel more comfortable, then you can move onto your own hardware.

What is the difference between DOCSIS 3.0 and DOCSIS 3.1?

As the transition from Wi-fi 5 to Wi-fi 6 in the wireless world has shown us, DOCSIS 3 was an improvement over DOCSIS 2. DOCSIS 3.x is a new specification for delivering high speed internet service via cable modems. It provides better performance than DOCSIS 2.x.

DOCSIS 3.x supports a maximum upstream speed (download) of 200Mbps and a maxi­mum downstream speed (upload) of 1Gbps. However, DOCSIS 3+ promises to be 10 times faster than DOCSIS 3.X at download speeds with a downstream speed of 10 Gbps.

If you're not a heavy user of high resolution videos, a DOCSIS3.0modeme will suffice for most people. You'll also be saving some cash by choosing a DOCSIS3 modeme that's built into a Wi-fi5routernowadays. Advanced users who want the best tech will probably go with a DOCSIS3modeme that's paired to a Wi-fi6orWi-fi6erouternowadays.

Does my modem require a battery back up?

In general, most modern modem/modem-router combinations do not include a backup battery. However, some older devices might offer one as an option. Modem manufacturers often add a backup battery to their products because they know that people who own these devices will likely lose power frequently. For example, someone living in a rural area where power outages are common would probably benefit from having a backup battery installed.

If you don't have a backup power supply for your modems, you'll still need to use a backup power source.

If I want to use voice services with my modem-routers, what do I need to know?

You may want to consider buying a combination device if you need both a land line and cellular connection. Many people now use their mobile phones exclusively for communication, so having a second port might be useful.

Can my ISP let me connect using my own modem?

Most people who buy their own DSL Modems do so because they can get better service for bester than what they would pay if they were renting one. In addition, buying a DSL Modems allows them to avoid having to deal with the hassle of dealing with their current phone company. However, before purchasing a new DSL Modems, make sure that your current phone company does offer DSL service in your area. Also, make sure that your new DSL Modems is compatible with your current phone line.
