Compare every internet provider in Cupertino, CA: coverage from FCC filings, plan prices checked monthly, and an address check for your street.
The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 74% of Cupertino, while its broader network reaches about 90% of the city. If AT&T reaches your address, it is the faster choice, with fiber speeds up to 5,000/5,000 Mbps reaching about 38% of the city.
The local map gets especially interesting in Monta Vista, where AT&T fiber covers about 43% of ZIP 95014, while Xfinity reaches about 23% there with its fastest cable tier. In ZIP 95015, AT&T fiber is the clear winner, reaching about 78%, with Xfinity covering about 22%. That makes ZIP 95015 unusually fiber-friendly, while parts of Monta Vista, Rancho Rinconada, West Cupertino, and Garden Gate still require a careful address check, particularly where older copper infrastructure may limit AT&T speeds. De Anza College students should verify apartment-specific service before signing a lease, since reliable Zoom, streaming, and gaming performance can vary by building. T-Mobile and Verizon are worth checking as fixed wireless alternatives, especially for budget-minded households, but coverage and performance change street by street, so confirm the exact address before choosing.

THE TAKEAWAY
Our recommendation for Cupertino
Xfinity’s cable service reaches 90.2% of Cupertino, giving many local addresses a strong chance of getting service. It is a reliable choice for most households, with up to 1200 Mbps download and 35 Mbps upload on the 1.2 Gig plan, which has a Speed Score of 89/100, while the 2 Gig plan reaches a Speed Score of 91/100 and is available to 74.3% of the city. That 91/100 headline score is above Cupertino’s city average of 56, but your address determines whether the faster 2 Gig option is available.

Starlink’s Residential Max plan offers up to 400 Mbps download and 40 Mbps upload with a Speed Score of 80/100, above Cupertino’s city average of 56, making it a competitive option.

About Starlink
Satellite internet gives Starlink broad availability, but its higher latency can be noticeable during video calls, gaming, and other real-time activities. Its strongest option is Residential Max, with up to 400 Mbps download and 40 Mbps upload for $130 per month, while the 200 Mbps and 100 Mbps plans cost $85 and $55 per month, respectively, and all three are available to 100.0% of Cupertino. Starlink can be a useful option where wired service is unavailable, but check your address for fiber or cable first, since those technologies are generally better suited to modern interactive use.

Its Fusion plan reaches 100% of Cupertino and offers the best HughesNet performance here, but you should check for faster fiber or cable options at your address first, since satellite may not be sufficient for modern needs such as frequent streaming, gaming, or video calls.

About Viasat Inc
Viasat is mainly an adequate fallback, so check whether a faster provider is available at your address first.

Because both options use satellite and have below-average Speed Scores, they may feel limited for demanding modern needs such as multiple video streams, gaming, or large downloads.

How We Analyze Internet in Cupertino
FCC Broadband Data
We use the FCC National Broadband Map, updated twice a year with provider-reported coverage at the census block level.
Speed Score
A state-wide percentile of each plan’s maximum advertised download speed against every option filed with the FCC in the state, all technologies on one scale. It is not a measured speed test.
Coverage Calculation
Provider coverage shows what percentage of census blocks in Cupertino report service availability from each provider.
Data Coverage for Cupertino
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.
Data source: FCC National Broadband Map (Broadband Data Collection), republished roughly twice a year; provider plan lists checked monthly.
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.
