Frequently Asked Questions

Is AT&T Fiber really better than Xfinity in Florida?

For most users, yes. AT&T Fiber offers advanced fiber technology with symmetrical speeds, no data caps, and strong reliability. However, Xfinity has wider availability and may be the only high-speed option in some areas.

Why are Xfinity upload speeds so slow?

Xfinity uses cable technology (DOCSIS) which allocates most bandwidth to downloads. Their upload speeds max out at 35 Mbps, while AT&T Fiber offers equal upload/download speeds up to 5 Gbps.

Can I get AT&T Fiber in my Florida apartment?

It depends on your building. Many newer complexes have AT&T Fiber, but some have exclusive agreements with other providers. Check with your property manager or use AT&T's address checker.

Is Xfinity's 1.2TB data cap enough?

For average users, yes. But households that stream 4K content, game online, and work from home can exceed 1.2TB. Xfinity charges $10 per 50GB overage (up to $100) or $30/month for unlimited data.

Which is better for gaming in Florida?

AT&T Fiber offers low latency for gaming (2-5ms) and symmetrical speeds. Xfinity can work well (10-20ms latency) but may experience congestion during peak hours.

The Bottom Line

Choose AT&T Fiber if: It's available at your address and you want high performance with low latency, especially for remote work, gaming, or multiple users.

Choose Xfinity if: AT&T Fiber isn't available, you want TV bundles, or you're looking for the lowest introductory pricing.
