EarthLink vs AT&T Fiber

How the two actually differ, which one wins on what, and how to tell which of them reaches your address.

By , Editor · Updated August 15, 2026 · Availability figures from the FCC Broadband Data Collection, as of December 31, 2025

Short answer: AT&T Fiber is the network; EarthLink is a way to buy it

These are not really competing technologies. AT&T Fiber operates its own network. EarthLink resells capacity delivered over other carriers' networks, so what you actually get depends on which network reaches your address — it may even be AT&T Fiber's. Compare them on billing, contract terms and support rather than on the connection, because the connection may be the same one.

  • EarthLink is reseller, operated by EarthLink LLC. AT&T Fiber is fiber to the home, operated by AT&T Inc..
  • EarthLink: the tiers available depend entirely on which underlying network reaches your address.
  • AT&T Fiber: plans commonly range from 300 Mbps up to 5 Gbps where available.
  • Their footprints overlap in few of the markets FiberNear tracks, so at most addresses only one of the two is actually orderable.
  • Both are built out address by address. Whichever reaches your specific property usually settles the question before preference does — FiberNear checks that free.

Speeds and footprints are advertised by each provider, vary by address, and change without notice. FiberNear does not set or guarantee them.

How often each one is actually available

Specifications decide which connection is better. Availability decides which one you can buy, and it is the part comparison pages usually skip. Across the 29 markets FiberNear holds FCC data for, this is how much of each city the two technologies reach at 100/20 Mbps or better:

Source: FCC Broadband Data Collection, residential fixed broadband, as of December 31, 2025. Figures are advertised availability self-reported by providers, not measured speeds. These are technology-level figures, not brand-level ones — the FCC's public summary files report how much fiber or cable reaches a city, but not which brand owns it, so no coverage percentage here should be read as a figure for EarthLink or AT&T Fiber specifically.

Common questions

Which is better, EarthLink or AT&T Fiber?
These are not really competing technologies. AT&T Fiber operates its own network. EarthLink resells capacity delivered over other carriers' networks, so what you actually get depends on which network reaches your address — it may even be AT&T Fiber's. Compare them on billing, contract terms and support rather than on the connection, because the connection may be the same one.
Is EarthLink faster than AT&T Fiber?
On advertised download speed the two are closer than most people expect. The difference that matters is upload: EarthLink is reseller and AT&T Fiber is fiber to the home, and those two technologies behave differently on upload and latency even when the download figure looks similar. Advertised tiers are set by each provider and vary by address.
Can I get both EarthLink and AT&T Fiber at my address?
Sometimes, but far less often than the coverage maps suggest. Both networks are built out street by street, and plenty of addresses that show inside both footprints can only actually order one. Entering your address is the only way to find out which — FiberNear checks it free and there is no obligation.
Is FiberNear paid to recommend one of these?
No. FiberNear is an independent comparison and referral service, not an internet provider, and it is not affiliated with, endorsed by, or sponsored by any carrier named here. We may be compensated if you choose to move forward with a provider, which never changes which options we show you.
