Google Fiber has the fastest average internet speeds in the US, followed closely by Verizon Fios. These two fiber internet providers have impressive download speeds, upload speeds, and ping rates.

RCN, MetroNet, and Xfinity also average respectable speeds. Like Google Fiber and Verizon Fios, MetroNet is a fiber internet provider, so it can give equal upload and download speeds. Starry and RCN, on the other hand, give customers slower upload speeds than the advertised download speeds—86.7 Mbps and 19.8 Mbps, respectively.

We came up with these findings by drawing data from 4.4 million speed tests that internet customers across the United States conducted with our speed test tool from March 1, 2020, to March 16, 2021. We use download speed as the main base of comparison between providers because most of our activity on the internet involves downloading data.

The fastest residential internet speeds usually top out around 1,000 Mbps. Xfinity and Google Fiber offer speeds up to 2,000 Mbps, but those plans are either cost prohibitive or have very limited availability, or both. And there are a few providers sprinkled throughout the US (like EPB Fiber Optics in Chattanooga, TN) that offer speeds up to 10,000 Mbps. But those are pretty rare and almost certainly overkill.

Almost every ISP has a gigabit internet plan nowadays. So to identify the internet service providers with the fastest advertised speeds in the US, we used data from the Federal Communications Commission’s Ninth Measuring Broadband America Report. We included providers on this list who surpassed actual-to-advertised speeds for most users according to the report (because it’s no use paying for top speeds if you’re constantly getting less than you pay for).

Pro tip:

Speaking of getting the speeds you pay for, you should regularly test your internet speed to make sure you’re getting the most out of your internet connection. Vroom-vroom!

What’s the difference between average speeds and advertised speeds?

The average speeds we’re discussing reflect what customers get from the internet plans they’ve purchased. But many of these providers also have Wi-Fi plans that give you faster speeds, if you so desire. To get a sense of just how fast a provider’s internet can go, take a look at its maximum advertised speeds.

Fastest internet providers by region

The fastest providers in New York City aren’t the same as the ones in Los Angeles. The US is a massive country, so we broke down our data set into four regional categories to help you find the fastest internet speeds in your neck of the woods.

Jump to: Northeast | Midwest | South | West

Fastest internet providers in the Northeast

Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont

RankProviderInternet typeAvg. download speedMax advertised download speedGet connected
#1 Verizon Fiber141.9 MbpsUp to 940 MbpsView Plans
#2 RCN Cable132.9 Mbps940 MbpsView Plans
#3 Xfinity Cable128.9 Mbps2,000 MbpsView Plans
#4 Cox Communications Cable128.0 Mbps940 MbpsView Plans

Verizon Fios takes the top speed spot in our rankings for the Northeast. That’s no surprise, seeing as the fiber internet provider also earned first place in J.D. Power’s 2019 U.S. Internet Service Provider Satisfaction Study for the East and came out on top of the American Customer Satisfaction Index (ACSI) Telecommunications Report 2018-2019 as well.

In particular, Verizon Fios had notably higher average upload speeds than other providers in the region, which is typical for fiber internet service compared to cable.

That doesn’t mean cable internet is slow. Four of the Northeast’s fastest ISPs are cable internet providers. All of them offer gigabit (or close) internet speeds.

Fastest internet providers in the Midwest

Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin

RankProviderInternet typeAvg. download speedMax advertised download speedGet connected

#2 RCN Cable132.9 Mbps940 MbpsView Plans
#3 MetroNet Fiber129.9 Mbps1,000 MbpsView Plans
#4 Xfinity Cable128.9 Mbps2,000 MbpsView Plans

With the exception of Xfinity, local internet providers dominate the Midwest. Allo Communications, Metronet, and RCN all have relatively small service areas in only a few states in the region:

  • Allo Communications is available throughout Nebraska.
  • Metronet is available in Indiana, Illinois, and Kentucky.
  • RCN is available mostly in East Coast cities but offers service in Chicago as well.

While these local providers offer the fastest speeds, they don’t have the widest availability. Xfinity offers a bit of both with better coverage and fast speeds. But it’s telling that the Midwest’s fastest internet providers are so limited and concentrated around bigger cities.

Pro tip:

Much of the rural Midwest exists outside of service areas for cable and fiber internet. If you’re out in the boonies but still want the best connection possible, check out our guide to rural internet.

Fastest internet providers in the South

Alabama, Arkansas, Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, D.C., and West Virginia

#2 Verizon Fiber141.9 MbpsUp to 940 MbpsView Plans
#3 C Spire Fiber129.2 Mbps940 MbpsView Plans
#4 Xfinity Cable128.9 Mbps2,000 MbpsView Plans

Both Xfinity and Google Fiber provide service in the South. There are also more fiber-only internet companies on this list in general, so it looks like the South is doing pretty well when it comes to high-speed internet access.

Fiber is the fastest type of internet, and it really boosts speed scores. But if a provider also offers DSL services, those can drag down the overall average speeds from that provider, which results in a lower score. You don’t have to worry about that here.

Fastest internet providers in the West

Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming

#4 Spectrum Cable103.5 MbpsUp to 940 Mbps (wireless speeds may vary)View Plans
#5 AT&T Fiber, fixed wireless102.9 Mbps940 MbpsView Plans

It’s no surprise that Google Fiber has the fastest internet in the West. It has the highest speed in the whole country. And in areas that don’t have access to the very fastest, you can still get ridiculously fast internet speeds with one of many fiber internet providers, whether you’re on the coast, up the mountains, or in the desert.

If you’re looking for top speeds, we’d advise splurging for fiber internet. It’s simply much faster, though many fiber networks have much smaller coverage areas than other types of internet.

Not surprisingly, Google Fiber has the highest speeds for fiber internet providers. It’s the fastest provider nationwide for all internet types. It also has exceptional upload speeds, reflecting fiber internet’s unique capability to provide symmetrical upload and download speeds.

RCN is the fastest cable provider, beating out much bigger cable providers like Xfinity and Mediacom. Other cable providers do frequently provide high-speed service, including gigabit speeds. And we’re also impressed by Starry Internet, another relatively small provider that’s been making inroads as a 5G-based fixed-wireless provider. Expect to see more 5G, fixed-wireless options in the future.

Frontier’s speeds are really impressive for a DSL provider, but keep in mind that Frontier also has fiber internet—so its total average could be weighted higher since fiber internet speeds are generally much faster than DSL internet.

What is the fastest type of internet?

Fiber-optic internet is the fastest type of internet. Across the US, fiber internet providers ranked highest in our speed comparisons. Cable internet also made a good showing among the fastest internet service providers in the US. Both fiber internet and cable internet offer speeds up to (and sometimes exceeding) 1,000 Mbps (1 Gbps).

Beyond cable and fiber, there are several types of internet connections, and each type can affect your speeds in different ways:

Fiber is currently the fastest type of internet available, with speeds up to 10,000 Mbps in a few areas. It uses glass fiber-optic threads bundled together to transfer light signals, which are fast and reliable over long distances. Fiber isn’t affected by speed issues common in older types of internet connections.

Cable internet uses buried copper coaxial cables and electrical signals to transfer internet. While it can reach gigabit internet speeds, cable has more limited bandwidth than fiber. This can cause network congestion when too many internet users in one area are online at the same time.

DSL stands for “digital subscriber line” internet. It uses landline phone wires to deliver internet, allowing much faster speeds than dial-up. But because it still uses older telephone infrastructure, DSL is less reliable than cable or fiber. Its top speeds max out around 100 Mbps.

Satellite internet uses wireless signals between your home, a satellite orbiting earth, and the provider. This tech can currently reach speeds up to 100 Mbps, but it has much higher latency than other types of internet because all your data has to travel literally thousands of miles. The satellite signals can also be interrupted by bad weather.

Fixed wireless internet works very similarly to satellite internet, but it uses radio tower transmitters as the midpoint instead of a satellite. The main limitation to fixed wireless is that it requires line-of-sight to transmit signals. Most fixed-wireless carriers currently offer limited speeds, often not reaching over 100 Mbps. But the technology has a lot of potential to deliver speeds that could match fiber, especially with the emergence of 5G.

Cellular connections, also known as mobile or wireless, connect your mobile devices to the internet via cell towers. This differs from other forms of internet because it’s not a one-to-one connection. Every mobile device connected to a cell tower shares the same bandwidth, which can dramatically affect speeds if the network gets congested.

How we ranked the fastest internet providers in the US

We took data from more than 4.4 million speed tests taken by users with our speed test tool between March 1, 2020, and March 16, 2021. We identified the internet providers with the fastest average upload and download speeds and ping rates (latency) in the US.

We ranked the internet providers based on download speed, since that’s the speed internet users depend on the most. It’s also the main speed that internet providers rely on when advertising their speeds and quality of service.

When it comes to download and upload speed, the higher the speed, the better. For latency, however, lower numbers mean faster response times and a smoother connection overall. Latency (also known as the ping rate) is the delay that happens when a signal is sent from a device to a network, or vice versa. It’s measured in milliseconds, and higher rates of latency lead to glitchy video and audio performance in streaming and online games.

Our data is based on averages across many different internet plans and locations, so your experience might not exactly match our results. It’s definitely possible for you to have service from one of the fastest internet providers and still have slower internet speeds. It’s also possible to get faster service from one of the slower internet providers.
