Internet Connection Types Explained - CNET (2024)

When comparing internet providers in your area, you're most likely checking available speeds and pricing along with the fine-print details like data caps and equipment fees. There's another factor to consider that is equally as important but easy to overlook: the connection type, or what technology your internet service provider uses to send internet to your home. We at CNET have encountered them all and can tell you first-hand the difference the connection type can make.

ISPs use wired or wireless connections (or a mix of the two). Wired connection types -- meaning a wire is connected directly to your home -- includefiber-optic, coaxial cable and copper (DSL) internet. Satellite internet, fixed wireless and the increasingly popular 5G home internet round out your potential wireless internet options.

So what's the difference between them all? This guide will walk you through the different types of internet connections that may be available in your area, how they work and what limitations you can expect from them. Connection types are listed in order of most to least recommended.

Locating local internet providers

Fiber internet: The best, but least available

Fiber-optic internet uses long, thin strands (fibers) of glass or plastic to send data as light signals. The result is speed and reliability that are superior to other connection types.

Fiber-optic can deliver download speeds as fast as 10 gigabits (10,000 megabits per second) or higher -- fast enough to download a 2-hour movie in HD in less than a minute -- but you're likely to find max download speeds around 1,000 to 5,000Mbps from most fiber-optic providers.

Locating local internet providers

Upload speeds, which are essential for working and learning from home, uploading to videos to social media and gaming online, are also significantly faster with fiber-optic service and typically mirror download speeds. No other connection type can deliver symmetrical upload and download speeds like fiber-optic internet.

Pricing for the ultraspeedy plans can easily run you $100 or more per month, but most providers also offer slower speed tiers (if speeds of 100 to 1,000Mbps can be consideredslow) for $40 to $90 per month. Other connection types may present slightly lower introductory prices, depending on the available providers in your area, but when you take into account the speeds you get for the price you pay, you're likely to find the best value with fiber internet.

Availability is the only real disadvantage with fiber. Laying enough fiber-optic cables to connect entire cities and regions is a huge logistical challenge, and with lots of competition and red tape to cut through, it's been slow going for any of the major service providers to expand coverage to underserved areas. Consequently, fiber internet is only available to around 40% of US households and primarily those in urban areas, according to the Federal Communications Commission.

Cable internet: Your standard connection

Cable internet lacks the full speed potential and reliability of fiber-optic service, but it's much more widely accessible. Cable is one of the most common types of internet connections -- available to nearly 90% of US households -- and you'll often find it bundled with TV packages. That makes sense, because cable internet uses the same coaxial connections as cable TV.

Though not as speedy as fiber internet, cable internet service is still one of the fastest connection types. Most cable providers offer a variety of speed options, including a gigabit plan with download speeds around 940Mbps. Upload speeds are a much different story, however, as few cable internet providers deliver upload speeds above 50Mbps. Speed reliability can also be a concern with cable internet as the connection type is susceptible to network congestion and slowed speeds, especially during peak usage times.

Cable internet pricing varies quite a bit among providers, but cable is, for the most part, one of the more affordable internet connection types. You can get a broadband connection from providers like Astound, Mediacom and Xfinity starting at around $30 per month or less. Spectrum, another big name in cable internet, has a higher starting price at around $40 per month but comes with max download speeds of 300Mbps.

5G home internet: A growing wireless alternative

Mobile internet is largely designed for your phone, but as the technology improves and speeds increase, 5G mobile connections are becoming more practical for home internet use.

With this internet connection type, a cell carrier such as T-Mobile or Verizon sends 5G signals in all directions. Many are picked up by cellphones, but for home internet, a router receives those signals and turns them into a home connection. It's a great way to get broadband without the need for running a line to your home or in some cases, dealing with the companies that have run those lines -- ISPs are notorious for low customer satisfaction ratings.

If you're living in a city or another area with strong cellular infrastructure, you might be able to connect over 5G, with providers like Verizon offering speeds up to 1Gbps. You'll also find cellular internet plans that use LTE, the previous generation of technology, or a mix of LTE and 5G.

When shopping for mobile internet for home use, it's probable that you will only have one or two plans to choose from with a flat rate for whatever speeds are available at your address. T-Mobile offers a single 5G plan ($60 per month for download speeds ranging from 72 to 245Mbps), while Verizon offers two ($50 or $70 per month for download speeds ranging from 50 to 300Mbps or 85 to 1,000Mbps, respectively).

Fixed wireless internet: Also wireless, but with a few strings attached

Another wireless internet option -- but one that may come with more steps and equipment while delivering slower speeds and less data -- is fixed wireless. Similar to 5G, fixed wireless providers send internet signals over the air. But unlike 5G, you'll need a mounted receiver with a direct line of sight to the nearest tower to receive those signals. Hills, trees, buildings or other obstacles nearby can distort or outright block your connection.

Fixed wireless internet speeds often range from 5 to 50Mbps. There are many variables that can affect the quality of the incoming signal, including distance from a local tower, so your available speeds may vary. Regardless of the speeds you can get, expect flat-rate pricing or around $50 per month. Plans also typically come with a monthly data cap of 200 to 300GB, depending on the provider.

Though fixed wireless has traditionally been a rural internet option, the connection type is rapidly expanding in metro areas thanks to providers like Google Fiber and Starry Internet. Instead of beaming services to individual residences, these providers send internet signals to entire buildings, such as an apartment complex, then run service to individual units via an Ethernet cable. These providers are capable of delivering speeds much faster than traditional fixed wireless service with gigabit speeds available in select areas.

DSL internet: A last resort before satellite

DSL (that's "digital subscriber line") is a fixed connection most popular in areas without access to cable or fiber internet. With DSL, your connection to the internet runs through copper phone lines. it's similar to dial-up service in that regard, but DSL is significantly faster than dial-up and won't tie up your phone line.

DSL internet is best for those in rural communities looking for a somewhat reliable and affordable internet connection. While it does lack the speed potential of pretty much every other internet type, it is typically a cheaper and sometimes faster alternative to satellite internet. Since DSL uses existing phone lines to deliver service, availability is high and providers can keep prices relatively low.

Satellite internet: When there are no other options

Satellite internet is the most widely available type of internet because it doesn't rely on ground-laid infrastructure like cables, cellular towers or line-of-sight antenna connections. Instead, you'll use a mounted dish to connect with geostationary satellites orbiting miles overhead. If you have a clear view of the southern sky, there's a pretty good chance that there's a satellite provider willing to install a dish and offer you service, for a price.

On average, today's satellite internet providers offer speeds that typically vary from 12 to 100Mbps. In most cases, that makes it a suitable option for smaller households who want to stream video, browse the internet and update social media.

New satellite providers -- namely Elon Musk's Starlink network, which began expanding service in select areas the last few years andAmazon's Project Kuiper-- are promising to bump those speeds up by using low Earth orbit satellites that are closer to the ground. That means that the signal doesn't need to travel as far, which also makes for a reduction in latency, or lag.

Increased competition in the satellite internet industry may help bring costs down for the consumer. Currently, satellite internet is the most expensive internet connection type, by far. Starting prices for satellite internet are around $60 per month, but that's often for slow speeds and low data allowances. If you want faster speeds or more data, satellite internet can quickly get up to $150 to $200 per month, and equipment fees will add another $15 or so to your monthly bill.

Finding the right internet service for you

So which kind of internet connection is right for you? It depends on several factors. The first thing to think about is your typical usage, and how much speed you really need. If you plan to surf the web and check email only, you can get away with a slower connection, but smaller households with users who stream videos, play games online, or upload files for work or school will ideally want access to download speeds of at least 100Mbps.

Costs are another key factor, obviously. Some providers bundle their various services to offer you a discount, but be aware that the promotional pricing might not last as long as the service contract. In that case, you'll pay more for the same service during the second year, for example.

In the end, the biggest factor is likely beyond your control and that's your location. Some parts of the US have lots of options for getting online, while others hardly have any options at all.

Whatever choices are available to you, understanding the different technologies at play will help you know what to expect before you sign up.

Internet connection types FAQs

What type of internet is Wi-Fi?

Wi-Fi is a way to connect to the internet, not a separate type of internet. With Wi-Fi, a router converts your internet connection into wireless signals and transmits them throughout your home. If you have a cable internet connection, your Wi-Fi is a wireless means of connecting devices to your cable internet service.

How do I know what type of internet connection I have?

Wireless connections are fairly obvious -- you have a satellite dish or antenna mounted for satellite or fixed wireless service, or your provider is Verizon 5G Home Internet or T-Mobile Home Internet.

Determining the type of wired connection you have can be a bit more of a challenge, but a good speed test should do the trick. If your speed test shows similar upload and download speeds, your connection is most likely fiber. Speed tests with download speeds over 100Mbps, especially in the 200 to 940Mbps range, but with significantly lower upload speeds, indicate cable internet service.

If your speed test shows download speeds around 100Mbps or lower, it's possible you have cable or DSL internet. In that case, take a quick peek at the back of your modem -- a coaxial cable means cable internet while a telephone line means a DSL connection.

What is considered broadband?

The FCC recently upgraded the speeds required to qualify as broadband from 25Mbps down and 3Mbps up to 100Mbps down and 20Mbps up. Consequently, many DSL services, which often fall below 100Mbps down and almost always below 20Mbps up, are no longer considered broadband internet. Satellite internet may have the ability to deliver 100Mbps download speeds, but the 20Mbps upload speed is a difficult threshold to cross, meaning satellite internet does not meet the requirements of a broadband connection in many cases.
