Buying Guide for the Best CenturyLink-Compatible Modem
When we talk about a CenturyLink-compatible modem, we are talking about the equipment you need to access/ bring internet service into your home. This happens via wired connections, meaning that you must plug in your computer into your modem directly to access the internet. Basically, the modem is what links your ISP to your home internet, and the only way for you to make sure that you enjoy the best internet access/ connectivity in your home is by investing in a good modem.
What then do you need to look out for in that CenturyLink-Compatible modem?
Features/ Specifications of the Modem
While there are various generations of DSL technology, each upcoming DSL technology/ system is faster than the previous version of DSL. At the same time, the local DSL tech might not have the fastest speeds, which means that the decision to buy a modem running on the latest DSL technology will be dependent on your ISP’s system. In this case, you need to talk to your CenturyLink representative before you buy the modem with the best DSL technology.
That said, you need to know the DSL systems on the market allow you to enjoy varied internet speeds.
The ADSL, for example, allows you to enjoy high speeds of up to 7Mbps, ADSL2+ reaches speeds of 20Mbps, Bonded ADSL2+ up to 25Mbps, VDSL2 is fast at 80Mbps, Bonded VDSL2 offers high speeds of up to 100Mbps, while GPON reaches a high speed of 1Gpbs.
Type of internet connection
The first thing you need to consider is the design of the modem, specifically the type of connection offered by the modem. Here, you will come across things like ADSL, ADSL2+, Bonded Internet, and GPON. We’ll look at these connections briefly below.
ADSL refers to the Asymmetric Digital Subscriber Line. The DSL lines are designed to deliver internet on specific frequencies that are not used by or for voice calls. As a result, the ADSL lines are capable of delivering internet download speeds up to 8Mbps. Their upload speeds are much lower, though – typically below 1Mbps. But to ensure that you access higher download speeds, modern modems make use of the advanced ADSL2+ system, which is faster and allows high download speeds of up to 24Mpbs.
VDSL or Very-High-Bit-Rate Digital Subscriber line refers to the internet connection speeds that reach super high speeds of up to 50Mbps and 100Mbps, respectively (VDSL and VDSL2). Thanks to these high speeds, you can use the modem when streaming videos in HD. VDSL2 is a more advanced system, and it makes use of vectoring technology, which reduces interference, hence higher-quality internet connections.
Bonded internet is used by modem, and it refers to a type of DSL internet line that works for ADSL and VDSL internet lines. It’s also called the channel bonded broadband, and it features twisting copper lines that increase the bandwidth and the range coverage for the DSL network.
Also known as the Gigabit Passive Optical Network. It refers to the fiber optic type of internet connection designed to allow for high internet stability at high speeds and over large distances. It’s better than the copper connections, and GPON systems boast maximum download speeds of up to 2,000Mbps.
Note that CenturyLink makes use of all these DSL broadband networks, which means that when you are buying a new modem, you need to make sure that it’s connected to the best DSL network for your neighborhood.
The DSL network in your neighborhood is an important factor when it comes to determining the compatibility of your modem. You might want to confirm the ISPs DSL details to ensure 100% modem compatibility.
Usage and Number of Connected Devices
While the number of devices you have in your home will often determine the type of modem you settle for, we recommend buying a modem that comes with extra Ethernet ports for wired connections. Relying on the USB port connection is not the most reliable approach to pick, and you may be forced to buy a different modem after some months. The Ethernet connections give you an extra layer of flexibility, and you won’t have to worry about the performance of your modem when you have more devices connected to your home network.
Wireless technology capabilities
For a modem that offers the best high-speed internet connection speed and overall reliable performance, you might want to invest in a dual-band modem or even one that runs on a tri-ban system. A high-speed modem (modem-router combo) will be based on a WiFi 5 or a WiFi 6 system, offering higher internet speed connectivity via an Ethernet system.
One thing you must look out for when buying a CenturyLink-Compatible modem is its remote connection capability. You need to make sure that the modem selected allows for connection from multiple sources of high-speed internet traffic. This is an important consideration when it comes to things like HD streaming, remote video conferencing, online gaming, and other high-speed reliant activities. Note that the only way for you to enjoy the best internet connection from CenturyLink is by opting for a CBRAS or a CenturyLink Broadband Remote Access Server Compatible modem.
Overall, the internet speeds from your modem will depend on the internet package you subscribe to. But this doesn’t mean that you shouldn’t look at the peak speeds that the modem is capable of offering. The speed is determined by the Gigabit ports of the modem. While some modems offer Gigabit speeds, others offer high speeds, but you cannot enjoy anything above 100Mbps. To enjoy Gigabit speeds, first, make sure that the modem is set up to offer Gigabit speeds. You also need to buy a modem with at least 4 Ethernet ports – at least one to connect to the modem and the rest to connect to your devices, particularly the ones that require high-speed internet performance.
Modem Technologies/ Specs
The best cable modems feature two important technologies – Channel Bonding and DOCSIS Standards.
DOCSIS stands for Data Over Cable Service Interface Specification, and it’s the technology or standard that determines how fast information travels to your home network from your ISP and back. The current DOCSIS standards for you to look for in a modem are DOCSIS 3.0 and DOCSIS 3.1.
DOCSIS 3.0 is the most common modem standard today, and it offers a maximum of 32 channels all running at once, at high download speeds exceeding 1Gbps at 1216Mbps. The newest highest speed modems will, however, run on the DOCSIS 3.1 standard. The DOCSIS 3.1 modems are capable of high download speeds of up to 10Gbps and upload speeds of up to 1Gbps. The DOCSIS 3.1 modems are future-proof and backward compatible with DOCSIS 3.0 systems.
The other important consideration you need to keep in mind is channel bonding. It refers to how information flows between your cable ISP and your home/office network. It combines multiple channels so that you have a system that allows more information passing through at the same time. Channel bonding appears as 16×4, 32×8, 24×8, etc. These numbers represent the number of channels for downloads versus the channels for uploads. A 32X8 channel bonded system has 32 download channels and 8 upload channels.
That said, it’s important to note that the maximum internet speeds you will be able to enjoy from the modem purchased pretty much depend on the service you’ve subscribed to. You cannot access gigabit speeds is the peak speed from the ISP is 300Mbps.
Do I have to use a CenturyLink Modem/ Router?
No. However, you need to make sure that the router you choose is compatible with the CenturyLink Service for the best internet experience. Choose one of the modems reviewed above for the best CenturyLink connectivity.
What is the difference between CenturyLink DSL and CenturyLink Fiber?
While routers are designed to use both DSL and Fiber, these two systems are completely different from each other. The Fiber system refers to the system that makes use of the underground fiber-optic cables running to your home via the ONT box (used in place of the ONT box), and the router is connected via the ONT box directly. Thanks to the setup of the fiber optic system, pretty much all routers are compatible with these fiber systems.
On the other hand, you have the DSL internet, which makes use of telephone lines for internet coverage. Given the telephone line setup, you must have a modem to be able to make that connection to CenturyLink. The router then connects to the modem, emitting WiFi throughout the network. The modem-router combo also uses the DSL system.
In between the DSL and the fiber system, you have the Transparent Bridging Mode, a system that has been set up because there are limited router-modem combos designed for the DSL systems. Because of the limitation, you need to make use of the CenturyLink modem/router system as the gateway system to third-party routers for the desired high WiFi speeds. This bridging is made possible by the Transparent Bridging Mode.
What does an N/A Modem Mean?
Essentially, an N/A modem means that the modem you are looking at hasn’t been tested, which means that it hasn’t passed the testing on specific CenturyLink technologies. Modems that have been tested and approved by CenturyLink will be marked tested or approved.
The modems reviewed above are the best of CenturyLink-Compatible modems. They are reliable and made to ensure the best internet connection. The speed of the modems will vary depending on the DSL system incorporated into the modem.
