The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 54% of the city, while its overall footprint reaches about 98%. If Sonic.net reaches your address, it is the faster choice, with fiber speeds up to 10,000/10,000 Mbps reaching about 53% of the city. AT&T is the safe fallback where Xfinity does not reach, mostly fiber overall across about 97% of the city, with its fastest common fiber tier reaching up to 5,000/5,000 Mbps in about 70%.
Local results vary sharply: Sonic.net leads ZIP 94578 at about 72%, while Xfinity reaches about 14% there and AT&T about 8%. In Broadmoor, Sonic.net reaches about 61% with its 10,000/10,000 Mbps fiber, while Washington Manor tilts strongly toward AT&T fiber, reaching about 68% with up to 5,000/5,000 Mbps. Estudillo Estates and Mulford Gardens deserve an address-level check because nearby blocks can have a different winner. Unwired Ltd, T-Mobile, or Verizon may be useful fixed-wireless budget alternatives, but coverage and speeds change street to street, so confirm the exact address before choosing.

THE TAKEAWAY
Our recommendation for San Leandro
Xfinity’s 1.2 Gig cable plan reaches 98.5% of San Leandro, giving most households a strong chance of getting up to 1200 Mbps download and 35 Mbps upload.

The faster 2 Gig plan scores 91/100 but is available to only about 54% of the city, so check your address before assuming it is offered.
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.

Our recommendation for San Leandro
Up to 200 Mbps download and 25 Mbps upload, with a 59/100 Speed Score, should handle everyday browsing, streaming, and video calls, though heavier simultaneous use may feel limited. Unwired Ltd’s fixed-wireless service is available to about 87% of San Leandro, and its score is about the same as the city average of 61, but fixed wireless has more performance variability than cable or fiber, so consider checking other providers first at your address.

Households needing fast everyday service at a bundled price can consider T-Mobile’s fixed wireless plans, including up to 500 Mbps download and 60 Mbps upload with an 80/100 Speed Score, above the San Leandro average of 61. That score makes it competitive, though fixed wireless can be more variable than wired connections for latency and consistency.

About T-Mobile
T-Mobile is a good fit for households that want up to 500 Mbps for streaming, work, and everyday browsing, with fixed wireless plans earning an excellent 80/100 speed score. The best-priced options require a qualifying postpaid voice bundle, and availability is address-dependent, with the listed plans reaching about 78% of San Leandro, so check your address before signing up because fixed wireless can be less consistent than fiber or cable.

Satellite service can support everyday browsing, streaming, and video calls, though its higher latency may be noticeable for gaming and other real-time uses.

Because satellite generally has more latency than cable or fiber, check what other technologies reach your specific address before choosing.

About Starlink
Starlink uses satellite internet, offering broad availability and up to 400 Mbps download and 40 Mbps upload on its Residential Max plan, but satellite latency can be noticeable during gaming, video calls, and other real-time activities. The $130/mo Max plan is the strongest option here, while the $85/mo 200 Mbps and $55/mo 100 Mbps plans are slower, so check for fiber or cable at your address first and use Starlink as a practical fallback when faster wired service is unavailable.

At $94.99 per month for the first 12 months, then $119.99, HughesNet’s Fusion plan buys up to 100 Mbps download and 5 Mbps upload, but its satellite connection has limited performance for the price.

About HughesNet

Since all three plans use satellite, HughesNet is best treated as a fallback for basic use, so check your address for fiber or cable first, even though these plans are available across 100.0% of San Leandro.

How We Analyze Internet in San Leandro
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 Leandro 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.
