The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 91% of San Ramon, while its overall footprint reaches about 98% 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 35% of the city.
The local split matters: in Gale Ranch, ZIP 94582, AT&T fiber leads at about 59%, while Xfinity covers about 39%, making fiber especially realistic there. In Crow Canyon, ZIP 94583, Xfinity is the clear leader at about 79%, while AT&T fiber reaches about 13%, so cable is the more likely high-speed option. Windemere and Dougherty Valley can vary by street, and the broader city figures are more useful than assuming one neighborhood represents all of San Ramon. Unwired Ltd is worth a look for fixed wireless, reaching about 97% of the city with speeds up to 300/25 Mbps, while T-Mobile, Etheric Networks, and Verizon provide additional fixed-wireless choices in parts of town. Coverage changes street to street, so confirm the exact address before choosing.

THE TAKEAWAY
Our recommendation for San Ramon
At $90/mo for 12 months, AT&T’s 5 GIG Fiber plan offers up to 5,000 Mbps both ways, making it a top-tier option with a 95/100 Speed Score, above the city average of 58. It is available to about 35% of San Ramon, so fiber access depends on your address. Where fiber is unavailable, AT&T Internet Air offers up to 300 Mbps download and 30 Mbps upload with a 72/100 score, but fixed wireless generally provides less consistent performance than fiber.
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 AT&T
AT&T offers strong value, with up to 1,000 Mbps symmetrical fiber for $50/mo or up to 5,000 Mbps for $90/mo, plus a $35/mo up to 300 Mbps fiber option, making it excellent for streaming, work, and busy households. Fiber availability is address-dependent at about 37% of San Ramon, while the broader fallback is Internet Air at $40/mo for up to 300 Mbps down and 30 Mbps up across about 68% of the city, so check your address for fiber first because fixed wireless may be less consistent for demanding use.

THE TAKEAWAY
Our recommendation for San Ramon
Unwired Ltd’s headline Speed Score is 59/100, with up to 200 Mbps download and 25 Mbps upload on its top plan, enough for streaming, video calls, and several connected devices. That score is about the same as San Ramon’s city average of 58, but fixed wireless can have more variable performance and limited capacity compared with cable or fiber, so consider checking other providers first for demanding or latency-sensitive use. The up to 200 Mbps plan is available to 97.1% of the city, though you should confirm service and performance at your specific address.
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 Unwired Ltd
Up to 200 Mbps download and 25 Mbps upload should handle streaming, video calls, and several connected devices for many households. Unwired Ltd’s fixed-wireless service is available to about 97% of San Ramon, but it is an adequate rather than top-tier technology and can be less consistent, so check for faster fiber or cable options at your address first.

Up to 150 Mbps download and 75 Mbps upload is suitable for streaming, video calls, and everyday connected-home use. Etheric Networks’ fixed wireless Lbr plan has a Speed Score of 58/100 and reaches 56.3% of San Ramon, so its performance is adequate but limited compared with stronger technologies, making it worth checking other providers available at your address first.

About Etheric Networks
Up to 150 Mbps download and 75 Mbps upload is enough for streaming, video calls, and everyday household use, though this fixed wireless plan is below average compared with faster internet options. Etheric Networks is worth checking if it is available at your address, but because fixed wireless can be less consistent and no fiber or cable plan is listed here, check for faster options first if your household has heavy streaming, gaming, or many connected devices.

Fixed wireless is adequate for streaming, work, and everyday use, though performance can vary more than wired service, and the 500 Mbps options are available to about 53% of San Ramon, so availability depends on your address.

Our recommendation for San Ramon
Satellite service can support everyday streaming and browsing, but its higher latency may be noticeable for gaming and video calls compared with wired connections. Starlink’s Residential Max plan offers up to 400 Mbps download and 40 Mbps upload for $130 per month, with a Speed Score of 80/100, making it a competitive option above San Ramon’s 58 average and available to 100.0% of the city.

About Starlink
Starlink uses satellite internet, which can provide broad availability and solid everyday speeds, though satellite connections typically have higher latency than fiber or cable. Its Residential Max plan offers up to 400 Mbps download and 40 Mbps upload for $130 per month, with a Speed Score of 80/100 and availability to 100% of San Ramon, while the 200 Mbps and 100 Mbps plans are slower alternatives. Since fiber or cable availability can vary by address, check for those options first if you need the most responsive connection for gaming, video calls, or other demanding use.

About HughesNet
At $39.99 to $94.99 per month for the first 12 months, HughesNet offers up to 25 to 100 Mbps download speeds, but its satellite plans are below average for speed and may feel limited for modern households. All three plans are available to 100% of San Ramon, yet you should check your address for faster fiber or cable service first, since HughesNet is mainly a fallback for basic browsing, streaming, and lighter internet use.

How We Analyze Internet in San Ramon
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 San Ramon report service availability from each provider.
Data Coverage for San Ramon
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.

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.
