The Facts You Know Before Buying
- After spotting a cable modem to purchase, you need to confirm if it is going to offer you the value that you are looking for. You should consider the following before you part with your cash:
- Compatibility with your cable provider: Not all modems work with all cable providers. It can be frustrating to buy one only to find that it isn’t compatible with your ISP. Therefore, it is paramount to check whether the modem appears in the ISP’s list of the compatible modems before you make a purchase.
- If the provider doesn’t have the list, get relevant information from customer forums or enquire it from the customer care representative.
- Speed: With fast a fast modem and fast cable Internet plan, you will be able to enjoy fast internet connection speeds. You can know how fast a modem is by confirming whether the modem utilizes DOCSIS 3.0 technology, which helps cable modems offer high internet speeds.
- Reliability and efficiency: It is vital not to rely only on the modem’s approval by Comcast. Seek to find further information from the relevant customer reviews about the reliability and efficiency of the modem.
- Standards Compliance: This refers to the technology used by ISPs to communicate to devices in their networks. Nowadays, most ISPs use Docsis 3.0 which is a newer version of Docsis 2.0 to provide super-fast internet speeds.
- Also, due to the increasing number of devices accessing the internet, ISPs have moved from IPV4 to IPV6 (Internet Protocol Version 6). The reason is that IPV6 allows more data transmission within a network and also more devices to connect to the network than IPV4.
- All cable modems are compliant with certain standards whether it is Docsis 2.0 or 3.0. You should, therefore, ensure that your cable modem is compliant with DOCSIS 3.0 standard if you want to enjoy the fastest internet speeds.
- Design: Cable modems are supposed to be functional so when it comes to their design, the simpler the design the better. The ports should be well-spaced to provide ample space for cables to attach and detach without interfering with other connections.
- If the router is designed with ventilation holes, always leave the holes open for better cooling.
- Wireless Standard: The codes you see on your router such as 802.11/a/b/g/n/ac/ad are known as the wireless standard (or protocol).They are used to rate the data transfer speed and range of routers. Here is what Most wireless standard is capable of;
- I. 802.11n – supports speeds up to 450 Mbps
- II. 802.11ac – supports speeds up to 1.3 Gbps.
- III. 802.11ad – supports speeds up to 4.6 Gbps
- Wireless 802.11ac is the most used standard today. However, wireless 802.11ad is the newest and is 4 times faster than the 802.11ac standard.
- Range: If you own a standard-sized home, most modern routers will cover your entire home without a problem. However, if your home is large, a single router will not cover your entire home. You will need to purchase long-range wireless routers or Wi-Fi extenders to extend your Wi-Fi range.
- Heat: All modems and routers get hot when in use and more so when overworked. In fact, manufacturers state that modems can operate at temperatures of up to 104 degrees Fahrenheit when overworked.
- To prevent them from overheating, always place them in open space and ensure their ventilation holes are kept open always.
- Advanced Features: Here are some key features you should look out for if you want to enhance your internet experience at home.
- A. Quality of Service (QoS): The QoS feature acts as a manager where it prioritizes devices on your home network and allocates more bandwidth to them.
- For instance, if your work is based at home, you can configure your network to prioritize the devices in your office than your kids’ phones or tablets. This will ensure that your work is not interrupted by your kids’ online gaming or video streaming.
- B. MU-MIMO: In full, MU-MIMO is multi-user, multiple-input-multiple-output. It allows the router to connect and communicate with multiple devices in its network more efficiently. This technology is extremely helpful in a business setting where you have a lot of people connecting to your network.
- Mu-mimo technology ensures that the speed of your internet remains constant even when many users are connected to your network.
- C. Beamforming: Beamforming technology is a clever piece of technology used in wireless routers to make their wireless signals more efficient. This feature focuses a router’s wireless signals towards the direction of the wireless devices rather than sending out signals aimlessly in every direction. This increases the range of connection and makes the connections stronger.
- Future-proofing: Future-proofing is buying the latest modem with next-gen technology with the hope that you’ll enjoy the best and fastest internet speeds when ISPs roll out the next technology in their cable services.
- It is good thinking but hard to implement as there are many variables such as your location, your ISP and the workings of the technology.
- In short, future-proofing might work out well for you but there’s also a huge probability that you might waste money on a modem that might not work in the future.
- Warranty: There’s no expected lifetime for cable modems but a glimpse at forums dedicated to cable modems sheds light on what you can expect. Based on the forums these cable modems start to deteriorate at the seven-year mark.
- At this age, most modems start to overheat, shutting down suddenly and then restart automatically. Therefore, make sure that your modem has sufficient warranty.
- Price: That said, the higher the specs, the more the cable modem will cost. Therefore, let your needs guide you so that you buy the correctly specced modem. Most lower-priced modems are suitable for home use but if you are running a business with many employees, you can look at higher specced versions to support your business’ needs

You will get the benefit of getting expert opinions about certain modems and getting firsthand experience from users who own the modems.

What about DOCSIS 3.1?
Docsis 3.1 is the next-gen internet standard for ISPs that provide cable internet. With this new standard, users will get data transfer speeds of up to 10 Mbps and enhanced download efficiency with better queue management for multiple downloads.
What’s more, Docsis 3.1 provides increased internet stability even at slow speeds. Even though Docsis 3.0 is capable of providing gigabit speed, its data transfer speed is rated at a maximum of 1 Gbps, which is 10 times slower than Docsis 3.1.
The good thing about the Docsis 3.1 standard for ISPs is that they can easily upgrade from DOCSIS 3.0 to 3.1 without having to change their cable infrastructure.
And since Docsis 3.1 is completely compatible with Docsis 3.0, subscribers with DOCSIS 3.0 modems won’t be obliged to purchase new modems but will get the option of upgrading to the new DOCSIS 3.1 modems if they want to enjoy the benefits of this new standard.
Reasons for Purchasing a Cable Modem Router Combo for Accessing the Internet Connection from Xfinity
You’ll most likely come across a modem/router set as you look for a modem for your network. The router/modem unit offers you an opportunity to buy a modem and a router in one box.
The two will function from the same table, performing their respective functions. You’ll undoubtedly like the fact that the combo has fewer wires, is easier to set up and has less clutter as compared to buying the two components independently.
It looks like a great idea, right? But, wait! In fact, given a chance, I would discourage you from buying this set. The major drawback of this unit is that you’ll have to replace the whole of it in case you need to upgrade your router.
On the other hand, improving an independent router is less costly and more comfortable as it won’t interfere with the functioning of your modem.
Buying of a Used Modem for Accessing Comcast Connection: Is it a good idea?
As much as it may seem to be a cheap option, don’t even think about buying a used modem for accessing Comcast internet connection.
There are high chances another Comcast user may have used a modem that’s not new, hence added to their accounts.
The other user may be from a different state from where you reside and their account is normally closed. However, the MAC address of the modem remains in their account.
Therefore, you won’t be able to delete the MAC address from the account, hence the inability to add it your account since the address is limited to a single account.
For that reason, you will have to take the used modem to a cable store of Comcast for its verification and addition to your Comcast account.
You shouldn’t continue paying high monthly modem bills while experiencing annoyingly slow cable internet connections. Get the value of your money and replace your slow modem with a one-time purchase fast modem that will make you forget about all your internet issues.
Choose the modem which is efficient and reliable, as well as the one that matches your cable internet plan and cable internet service provider.
