EarthLink vs ATT: Compare Fiber Plans and Contracts

EarthLink vs AT&T usually comes down to the offer at your address, not a rule that one brand is better. Both advertise fiber plans with equal upload and download speeds and unlimited data. AT&T Fiber runs its own network and advertises no annual contract. EarthLink sells service over other carriers' networks, and its service agreement covers plans sold for a fixed term, so ask whether your quote is one of them and confirm the plan offered at your home is fiber. Then compare the written offers side by side before you order.

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.

Gigabit fiber and multi-gig speed tiers: EarthLink vs AT&T Fiber side by side

Both networks publish tiered plans, and the tier class matters as much as the top-line speed. Here is what each side offers as a tier, based on the plans each provider currently advertises.

EarthLink offers resold service, tiers set by the underlying carrier.
AT&T Fiber offers multi-gig fiber, up to 5 Gbps advertised where available.
Only AT&T Fiber is fiber, so its gigabit tier delivers matching upload speed. EarthLink's advertised gigabit tier is a download figure, and its upload runs materially slower on the same plan.
Tier availability varies by address. A multi-gig plan advertised in a market is not offered at every address inside that market, since it depends on whether the local optical distribution supports it.

Tier classes are derived from each provider's own advertised plans and change without notice. FiberNear does not set or guarantee speeds.

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:

AT&T Fiber is fiber, and fiber reaches a median of 64.2%.

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 about fiber internet availability

Which is better, EarthLink or AT&T Fiber?

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.
