The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 82% of Fairfield, although its overall footprint is about 84%. If AT&T fiber reaches your address, it is the faster choice, with speeds up to 5,000/5,000 Mbps reaching about 15% of the city.
In Paradise Valley, Xfinity leads 94533 at about 68%, while AT&T fiber reaches about 27% of that ZIP, making it one of the better places to check for symmetrical high-speed service. Cordelia is even more cable-oriented, with Xfinity reaching about 79% of 94534, while AT&T fiber reaches about 4%, so Green Valley and nearby residential pockets deserve an address-level lookup rather than assumptions based on the broader city. Students at Solano Community College should be especially careful with apartments, where older DSL or copper infrastructure can mean a poor fit for Zoom, streaming, or gaming. Verizon, T-Mobile, and smaller fixed-wireless providers such as unWired Broadband can be worth checking where cable or fiber is unavailable, but their reach varies considerably. Coverage changes street by street, and Travis Air Force Base area addresses may differ too, so confirm the exact address before choosing.

THE TAKEAWAY
Our recommendation for Fairfield
At $90/mo for 12 months, AT&T’s 5 GIG Fiber plan offers up to 5000 Mbps both ways, a $150 reward card, and a Speed Score of 95/100, making it a top-tier option for the price. That score is above Fairfield’s city average of 58 and is competitive for demanding households, though this plan is available to only about 15% of the city. Address availability matters because AT&T also serves some locations with Internet Air, which offers up to 300 Mbps download and 30 Mbps upload at $40/mo with a Speed Score of 72, while fiber remains the stronger technology where available.

About AT&T
At $35/mo, AT&T’s fiber plan buys up to 300 Mbps, while $50/mo buys up to 1000 Mbps both ways and $90/mo buys up to 5000 Mbps both ways, making it excellent value where fiber is available. Fiber plans reach about 20% of Fairfield, while the 5 Gig option reaches about 15%; elsewhere, Internet Air offers up to 300 Mbps download and 30 Mbps upload at $40/mo across about 38% of the city, but fixed wireless can be less consistent and may not be sufficient for demanding modern use, so check your address for fiber first.

THE TAKEAWAY
Our recommendation for Fairfield
For the price you are quoted, unWired Broadband’s value depends on whether your address can receive its up to 400 Mbps download and 50 Mbps upload Lbr Fixed Wireless plan, which has a Speed Score of 80/100. That top plan is competitive with Fairfield’s 58 average, although fixed wireless can be more variable than wired service, and it covers about 5% of the city. The 200/25 Mbps plan scores 59/100 and the 100/20 Mbps plan scores 21/100, so those offer limited performance compared to alternatives and warrant checking other providers first.

About unWired Broadband
At the monthly price you’re quoted, unWired’s best value in Fairfield is up to 400 Mbps download and 50 Mbps upload, with an excellent 80/100 Speed Score, although that plan reaches only about 5% of census blocks. Because all three offerings are fixed wireless, availability and performance depend on your address, while the fallback options of up to 200/25 Mbps or 100/20 Mbps may be only adequate for modern households, so check for faster fiber or cable service first.

How We Calculate Speed Score
The Speed Score is a state-wide percentile from 0 to 100. It answers one question: of every internet option filed with the FCC in this state, across every technology, what share is slower than this plan’s maximum advertised download speed?
What goes in:
- The plan’s maximum advertised download speed, as the provider files it with the FCC and lists it for sale.
- Every other serviceable option in the state from the FCC Broadband Data Collection, counted by the census blocks it reaches.
Speed Score = share of the state’s filed options with a lower advertised download speed
A score of 85 means this plan’s advertised speed beats 85% of the options filed in the state. Fiber, cable, DSL, fixed wireless and satellite are all on the same scale, so a 1,000 Mbps plan scores the same whoever sells it.
What it is not: a measured speed test. It does not include latency, upload speed, reliability or congestion. Real throughput at an address varies with wiring, equipment and time of day.
How providers are ordered on this page: each provider’s tier scores are averaged across the census blocks it serves, then multiplied by the share of the city it reaches. Wired providers rank ahead of wireless-only ones, and satellite last, because their filings describe a signal footprint rather than a plant. The same rule sets the title and the 30-second verdict.

How We Calculate Capabilities
Estimated Capabilities predict how well each internet plan supports common household activities based on speed requirements and connection type.
Rating Scale:
- Excellent – Optimal performance, handles peak usage easily
- Good – Reliable performance with minimal issues
- Fair – Functional but may experience slowdowns during heavy use
- Poor – Not recommended; expect frequent buffering or lag
How We Rate Each Category:
Streaming
Based on download speed. 4K streaming requires 25+ Mbps per stream; HD requires 5+ Mbps. We account for multiple simultaneous streams.
Multi-device
Evaluates total bandwidth capacity divided by typical household device count (phones, tablets, smart TVs, computers). Fiber and cable handle many devices better than DSL or satellite.
Gaming
Considers both upload speed (for sending game data) and latency (ping time). Fiber and cable excel here; satellite connections struggle due to inherent signal delay.
Whole Home
Assesses whether the connection can reliably serve an entire household during peak evening hours. Factors in technology type (shared vs. dedicated bandwidth) and total speed capacity.
Note: Actual performance depends on your specific location, network congestion, and equipment quality.
