Not all plans are available in all areas. Provider plan, availability, and speed tier data provided by BroadbandNow.com. Speedtest real-world data is only present where sample size has reached significance within a region. Additionally, averages may include aggregated tests across multiple Internet Types (Fiber, DSL, Cable, etc.).
In most U.S. cities, fiber internet is a luxury—available in pockets, if at all. In Cary, it’s the default. Google Fiber and AT&T Fiber blanket most of the city, offering symmetrical gigabit plans that make buffering and lag a thing of the past. Perhaps that’s no surprise for a city that boasts it’s “at the heart of central North Carolina’s renowned Triangle region,” famous for its technology-focused businesses and schools.
But when it comes to speed, which fiber provider takes the lead? Based on Speedtest data collected in the second half of 2025, Google Fiber edges out AT&T for the top spot, with median download speeds of 433.43 Mbps and uploads at 333.93 Mbps. AT&T isn’t far behind, posting a still-impressive 345.38 Mbps down and 285.04 Mbps up. Both providers cover the vast majority of Cary—86% for Google and 93% for AT&T—making fiber a realistic option for most households.
Your internet needs depend on how you actually use your connection. For most households of three to four people watching a moderate amount of streaming video and performing simpler work-from-home tasks such as emailing, Slack, Zoom, etc., a 300 to 500 Mbps plan is more than enough. But for creators, tech professionals, or large households, gigabit speeds and strong upload performance make a noticeable difference.
How to Pick the Right Internet Provider in Cary, NC
Here are some practical tips:
Check Your Address
Many ISPs tout citywide coverage, but the reality is more complicated (like if your building isn’t wired for fiber). Use provider lookup tools or Speedtest’s zip code breakdowns to verify.
Consider More Than Speed
Reliability, customer support, and data caps matter just as much. Many fiber plans, for example, include unlimited data and no equipment rental fees. Watch out for plans that include data caps and extra charges.
Think About Uploads
If you send large files, stream on Twitch, or make frequent video calls, symmetrical upload/download speeds (only offered by fiber) are a game-changer.
Match a Plan to Your Needs
Don’t pay for 1 gigabit if you’re just browsing or streaming a few hours a night. On the flip side, don’t skimp if you’re running a business from home.
Read the Fine Print
Promo rates often expire after 12 months. Check for hidden fees, contracts, or equipment rentals that inflate the total cost.
