The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 47% of the city, while its overall footprint reaches about 95%. If AT&T’s fiber reaches your address, it is the faster choice, with speeds up to 5,000/5,000 Mbps reaching about 54% of the city. In the citywide picture, Xfinity and AT&T are the practical heavyweights, but the winner can change from one street to the next.
In Tamalpais Park, AT&T wins with fiber coverage reaching about 68% of the ZIP, while Xfinity covers about 18% with cable speeds up to 1,200 Mbps. ZIP 94942 is similarly fiber-friendly, with AT&T reaching about 55% and Xfinity reaching about 34%, so residents in Sycamore Park, Cascade Canyon, or Boyle Park should still verify the exact address rather than assume the neighborhood tells the whole story. Unwired is worth checking as a fixed-wireless budget alternative, reaching about 84% of the city with speeds up to 300/25 Mbps, while T-Mobile and Verizon offer smaller fixed-wireless footprints. Coverage changes street to street, so confirm the exact address before choosing.

THE TAKEAWAY
Our recommendation for Mill Valley
Xfinity’s cable service reaches 95.2% of Mill Valley, giving most addresses access to the up to 1,200 Mbps 1.2 Gig plan, which has a strong 89/100 Speed Score. It is a solid, reliable cable option, and Xfinity’s top score of 91/100 is above the city’s 61 average. The up to 2,000 Mbps 2 Gig plan scores 91/100 but has more limited address availability, so confirm which tier your specific home can receive.
Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.
About Xfinity
Xfinity reaches about 95% of Mill Valley, so most households have a strong chance of getting its cable service. Its best local options are excellent for most uses, including up to 1.2 Gig for $100 per month across about 95% of the city and up to 2 Gig for $100 per month in about 47% of the city, while the widely available up to 1 Gig and 500 Mbps plans offer good value; check your address because the fastest option is not available everywhere.

Up to 200 Mbps download and 25 Mbps upload, with a Speed Score of 59/100, is suitable for streaming, video calls, and several connected devices. Unwired’s fixed wireless service offers limited performance compared with alternatives, and its score is about the same as Mill Valley’s 61 average. The Residential 200 Mbps plan is available to 83.5% of the city, but confirm service at your address before choosing it.

About Unwired Ltd
Unwired Ltd’s fastest option is up to 200 Mbps download and 25 Mbps upload, which should handle everyday browsing, streaming, video calls, and a connected household, though fixed wireless can be less consistent than cable or fiber. That plan is available to about 84% of Mill Valley, and the provider also sells lower-speed options, so check your address for faster cable or fiber service first if you need especially reliable performance for heavy streaming, gaming, or large uploads.

Our recommendation for Mill Valley
5G fixed wireless can support everyday streaming, video calls, and browsing, with the Verizon 5G Home plan offering up to 300 Mbps download and 75 Mbps upload. Its 72/100 Speed Score is above Mill Valley’s 61 average, making it a competitive option, though fixed wireless can be less consistent than wired connections. Address-level availability matters because this plan reaches about 45% of the city, so check whether 5G Home is offered at your specific address.

About Verizon

Households seeking reasonably fast home internet for streaming, remote work, and multiple users can consider T-Mobile fixed wireless, with up to 400 Mbps download and 50 Mbps upload on Rely or up to 500 Mbps download and 60 Mbps upload on its 500 Mbps plans. Its 80/100 Speed Score is above Mill Valley’s city average of 61, making it competitive, though fixed wireless can be more variable than wired service. These plans are available to about 48% of the city, so verify your address, and note that the $35/mo Rely price requires a qualifying postpaid voice line and bundle.

About HughesNet
HughesNet costs $39.99 to $94.99 per month for the first 12 months, then $49.99 to $119.99, but the satellite plans offer only up to 25 to 100 Mbps download and have below-average Speed Scores, so you should check for faster internet options first. Fusion is the strongest choice at up to 100 Mbps download and 5 Mbps upload for $94.99 initially, while Select and Lite trade speed for lower prices. HughesNet reaches 100.0% of Mill Valley, but satellite’s latency and limited performance may not be sufficient for modern households with heavy streaming, gaming, or video calls.

How We Analyze Internet in Mill Valley
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 Mill Valley report service availability from each provider.
Data Coverage for Mill Valley
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.
