90 Days on AT&T Fiber 1 Gig: The Honest Verdict
We ran AT&T Fiber 1 Gig in a household of four for 90 days, logging uptime, delivered speed, and every interaction with support.
What AT&T Fiber Gets Right
- Delivered speed is nearly perfect. Median download and upload both stayed above 97% of advertised for the entire 90-day period, with zero measurable peak-hour degradation — a direct benefit of dedicated fiber not being shared with neighbors.
- Uptime. We logged 99.97% uptime — about 8 minutes of downtime across the full 90 days, all from a single scheduled maintenance window.
- Price stability. No mid-contract increase, no promotional cliff — the price on day 1 matched the price on day 90.
Where AT&T Fiber Falls Short
- Availability is the real constraint. AT&T Fiber only reaches about 30% of AT&T's total footprint — most of the country still can't get it.
- The included BGW gateway's WiFi range is mediocre — coverage past 2 rooms required adding a mesh extender in our test home.
- Customer service wait times were longer than Xfinity or Cox in our comparative testing — averaging 11 minutes to a human versus 3-7 minutes for cable competitors.
The Verdict
Where it's available, AT&T Fiber is arguably the most consistently high-performing consumer ISP we've tested — the delivered-speed numbers back the marketing almost perfectly. The catch is availability, not performance: check att.com/internet for true Fiber eligibility before assuming Internet Air is your only AT&T option.
