What is Gigabit Internet?
Gigabit Internet is a cutting-edge high-speed internet connection that guarantees uninterrupted online gaming and smooth video conference calls. The purpose of this technology is to provide data speeds of 1 gigabit per second, which equals 1,000 megabits per second.
Gigabit internet is ten times faster than the broadband speed of 100Mbps commonly used today. With these speeds, you can effortlessly download files in seconds or stream a full HD movie in just a few minutes. Additionally, you can engage in graphics-intensive gaming without experiencing any frustrating lag.

Customer Feedback
Additionally, we considered feedback from users who have incorporated these modems into their daily lives alongside our evaluations. To gain insights into reliability, longevity, and overall customer satisfaction, we thoroughly examined user reviews on websites. This ensures that our recommendations not only meet requirements but are also aligned with users’ actual experiences.
Ultimately, we managed to decide on the best gigabit modems available. These modems showcase technical specifications and consistently deliver on their promises. Choosing the modem to enhance your internet connection speed is an important decision, and we wanted to provide you with all the necessary information to make an informed choice.
Things To Consider Before Buying A Gigabit Modem
If you enjoy watching movies of the highest quality and have devices connected to the internet simultaneously, having a fast internet connection is essential. To upgrade to a high-speed internet connection that can reach speeds up to 1Gbps, the first step is to replace your modem.
While some internet service providers (ISPs) offer their modems, they charge a fee, which can become quite expensive over time. That’s why getting your modem is recommended, as it performs better and saves you money in the long run.
In this section, we’ll discuss all the factors about Gigabit modems that everyone should consider before purchasing. Without further ado, let’s dive in!
Broadband Standard
First and foremost, it’s crucial to be aware of the technology trends regarding modems. The performance of a modem largely depends on the broadband standard it utilizes.
That said, it’s important to know that the current top broadband standard is DOCSIS 3.1. This new standard is ten times faster and more advanced than the DOCSIS 3.0 standard. In DOCSIS 3.1, standard modems perform better thanks to the OFDM signal processing technique.
This technique provides downstream channels resulting in quicker internet speeds. With DOCSIS 3.1, speeds of up to 10Gbps are possible, while DOCSIS 3.0 can only reach a maximum of 1Gbps. However, it’s worth noting that most internet service providers currently only offer up to 1Gbps plans, so both DOCSIS 3.1 and 3.0 modems will work perfectly fine.
Internet Speed Limit
As previously mentioned, DOCSIS 3.1 modems may provide 10Gbps internet rates. In contrast, DOCSIS 3.0 restricts speeds to 1 Gbps. Few ISPs offer plans beyond 1Gbps these days. You may examine the modem’s maximum internet speed and pick one that meets your demands.
Acquiring a modem that can support 10Gbps speeds is pointless since no ISP provides such fast internet services. However, the best choices now are DOCSIS 3.1 or 3.0 modems with up to 1Gbps speeds.
Compatibility
Before buying a new modem, verify if your ISP accepts third-party modems. Additionally, if your ISP allows third-party modems, make sure they support your ISP. Most modems on this page are compatible with big ISP brands, including Xfinity, Cox, Spectrum, and others.
Gigabit Ports
When looking for gigabit modem options, it’s essential to consider the number of ports. While most modems only have one ethernet port, there are also options with two or more ports. Having Ethernet ports allows for setting up connections, especially in office settings.
Additionally, it’s essential to ensure that the ethernet port on the modem is a gigabit port delivering 1 Gbps speed.
Build Quality And Design
Other factors to consider are the design and build quality of the modem. Unlike old models, modern modems are not unattractive. You can find stylish options on the market that you won’t feel the need to hide away.
It’s also worth checking for a built modem that can withstand drops without issues. Some modems even offer wall mounting options if that’s something you’re interested in.
Warranty
Lastly, when purchasing a modem, it’s crucial to consider sticking with well-known brands. It’s because reputable brands are usually reliable in offering support if any issues arise with the modem.
Additionally, opting for brands provides the added benefit of product warranty coverage. While certain popular brands offer a one-year warranty, some extend it to a two-year period, which is even more advantageous for customers.
Frequently Asked Questions
A: We recommend using a modem with a 32×8 configuration. If you want to ensure your internet connection remains future-proof, consider getting a modem that follows the DOCSIS cable company standards, specifically DOCSIS 3.1. This version supports download speeds of up to 10 Gbps. Remember that it should have Ethernet ports to handle that maximum speed.
A: The gigabit modems mentioned in this article typically range in price from $150 to $300 when purchased brand new. If you’re open to the idea, you might be able to save some money by considering a used or refurbished modem; just make sure to buy from a reputed seller.
Most internet service providers (ISPs) offer modem equipment for their subscribers. However, there may be a fee associated with it. While the monthly cost for renting an ISP’s modem is usually low, those expenses can accumulate over time.
That’s why purchasing your gigabit modem could potentially be a long-term investment as long as its capabilities align with the speed of your current internet plan.
No, achieving speeds of 1Gbps is possible with DOCSIS 3.0 technology.
However, it’s important to remember that DOCSIS 3.0 is a standard that will eventually be phased out. Therefore, it might be an idea to consider purchasing a modem that follows the DOCSIS 3.1 standard while still being compatible with DOCSIS 3.0.
Furthermore, DOCSIS 3.0 has a speed of around 1Gbps, whereas DOCSIS 3.1 can handle speeds up to 10Gbps. If you plan to upgrade your plan to a gigabit package in the future, investing in a DOCSIS 3.1 modem could be the better choice for you.
The Bottom Line
If you’ve made it this far, we hope you’ve already checked out our selected list of gigabit modems. We provided all the information and specifications for each modem option making it easy for anyone to compare and find the ideal fit.
It’s crucial to have a combination of internet service provider, modem, and router to maximize your internet speed.
Remember to check your internet plan speed limits before buying any equipment. You wouldn’t want to invest in something that supports speeds your plan doesn’t offer. Look for indicators of a quality gigabit modem to assess your internet requirements. Choose a reviewed option that suits your budget.
However, if you still have any doubts, we highly recommend going through our buying guide, as it can greatly assist you in selecting the modem from our list.
