AT&T internet services (Fiber and Internet Air) come in sixth place in Reviews.org's Fastest Internet Provider report. Delivering internet across 26 states, its average download speed is 187Mbps (for reference, Google Fiber offers the fastest fiber internet at around 250Mbps). Its 5G service called Internet Air offers speeds of 90–300Mbps.

Fiber is the best when it comes to internet service. Due to its symmetrical speeds, mobile bundle discounts, and new-customer deals, many enjoy the superfast connection that fiber can provide. AT&T Fiber goes all the way up to 5,000Mbps, and most customers actually love it.

These five cities are home to the fastest AT&T internet download speeds in the country.

It’s worth noting that many of the cities in our chart belong in California. This makes sense as AT&T internet is widely available in Northern and Southern California (and it’s the only state that isn’t part of AT&T’s copper shutdown finalizing in 2029).

You can find excellent speed in other big cities such as Austin, Texas, offering AT&T Fiber speeds up to 5Gbps across much of the city. Kansas City, Missouri, has solid fiber coverage up to 5Gbps. And San Antonio, Texas, is another solid one, with plans to grow its fiber to Armed Forces bases across the San Antonio area.

While speeds aren’t this fast everywhere, most customers are still likely to get adequate speeds from their AT&T internet. Lauren Hannula, an AT&T customer living in San Diego, pays for the Fiber Internet 300, which delivers advertised max speeds of 300Mbps. She just ran a speed test in January 2025, and here are the results:

As you can see, the download speed is even better than the speed she currently pays for (the 300Mbps plan). She did point out that her upload speed is usually symmetrical (the same as the download speed). But, she says, “Today has been a little laggy.”

Let’s head to the other side of the United States now. My former colleague, Becca S. lives and works in Wyoming, Michigan, as a Registered Nurse. She’s been paying for AT&T internet for several years now. She currently pays for the same Internet Fiber 300 plan as Lauren Hannula (in San Diego). A day after Lauren, Becca ran a speed test through our site, and you can see how they match up.

Her download speed is also running on the higher side at 343Mbps, and her upload speed more closely matches it.

Not sure if you’re getting fast enough internet speeds from AT&T? You may be able to find other options in your area. Run a search with your zip code below.

Our guide to fastest internet providers analyzes speed test data, several personal reviews, and input from real customers. Google Fiber takes the crown, followed by Verizon Fios, Cox, Xfinity, and Spectrum. For a flat rate of $70 per month, Google Fiber delivers 1,000Mbps—so speedy, so smooth. I personally have it, and I’ve never looked back.

Verizon Fios comes in second. Though you can only find it on the East Coast, it beats out most non-fiber providers. Take a look at how we break down different elements of its service in our honest deep dive.

For three to five people in a house who want to stream, game, or make video calls on three or more devices, we recommend 100–300Mbps.

We recommend AT&T's 300Mbps plan. It comes with unlimited data, no contracts, and 300Mbps for downloading and uploading. Lauren Hannula uses the 300 Fiber plan and states, “I love my AT&T fiber more than someone should love a utility.”

We recommend the 300Mbps plan as the sweet spot for a mid-sized family.

The average U.S. household has more than 17 connected devices, including fitness equipment, digital personal assistants, gaming consoles, thermostats, security cameras, smart watches, and the like). But GIG plans are overkill. Even with that many devices, 300Mbps can get the job done nicely.

Do you need AT&T’s GIG plans that are 57x and 134x faster than cable internet?

Respectfully, no.

There are cases where a GIG plan could be a good idea— like if you live in a big household and share Wi-Fi with a bunch of other people, if you're into content creation and livestreaming, or if you have a nice VR gaming setup in your house.

Here’s what you can do with different internet speeds:

To back up its internet plan speeds, AT&T has a guarantee that offers customers a full-day credit for a qualifying outage of 20 minutes. Use your state, service, and zip code to see if there’s an outage at your address.

No fiber available? Internet Air (AT&T’s 5G home internet service) may be a good 5G internet option if there’s coverage at your address. The wireless service’s reliability and strength depends on the 5G network in your area, and other factors like weather and network congestion can disrupt signals. But Internet Air offers download speeds between 90Mbps and 300Mbps, and you can get the same internet deals with AT&T Internet Air that you do with AT&T Fiber. So don’t worry, you can definitely stream your favorite Netflix show (life priorities, right?).
