Our recommendation for Walnut Creek
At $90 per month for 12 months, AT&T Internet 5 GIG offers up to 5,000 Mbps both ways, plus a $150 reward card, making it a top-tier fiber option with a 95/100 Speed Score, above Walnut Creek’s city average of 64.

About AT&T
AT&T offers strong value, from $35/mo for up to 300 Mbps to $90/mo for up to 5,000 Mbps, with fiber plans providing excellent, symmetrical speeds for demanding work, streaming, and gaming. The fastest fiber options are address-dependent, reaching about 27% to 30% of Walnut Creek, while Internet Air reaches about 54% with up to 300 Mbps download and 30 Mbps upload, so check your address for fiber first because the fixed-wireless fallback may be less consistent for modern heavy use.

About Verizon
Verizon’s 5G fixed wireless service offers up to 300 Mbps download and 75 Mbps upload, which is a good fit for streaming, video calls, and typical household use, though performance can vary with wireless conditions.

About Starlink
Satellite internet gives Starlink broad reach, but its higher latency can make gaming, video calls, and other real-time activities less consistent than wired service. Its Residential Max plan offers up to 400 Mbps download and 40 Mbps upload for $130 per month, with lower-priced options at up to 200 Mbps for $85 or 100 Mbps for $55, and each plan is available to 100.0% of Walnut Creek. Starlink can be a useful fallback, but check whether fiber or cable is available at your address first, since those technologies are generally better for modern, latency-sensitive use.

How We Analyze Internet in Walnut Creek
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 Walnut Creek report service availability from each provider.

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.
