The 30-Second Verdict
UpdatedStart with fiber, because San Leandro has genuinely good options here. Sonic.net runs symmetrical fiber up to a blistering 10,000/10,000 Mbps across about 53 percent of the city, and it dominates Mulford Gardens (94578) at over 71 percent and Broadmoor (94577) at 61 percent. AT&T fiber covers roughly 70 percent of the city with speeds up to 5,000/5,000 Mbps, and it clearly rules ZIP 94579 at 68 percent. Either is overkill-grade for heavy work-from-home, big uploads, competitive gaming, or a busy house full of devices. But be honest with yourself: if you mostly stream, browse, and hop on Zoom, Xfinity cable covers about 54 percent of the city at up to 2,000/300 Mbps and is usually the cheaper, plenty-fast call. If neither wired option reaches you, Unwired’s fixed wireless (about 87 percent, up to 300/25 Mbps) is a solid budget backup, with Starlink satellite (220/30 Mbps) as the true last resort. Coverage flips street to street, so confirm your exact address — and Chabot students, verify your unit is actually wired for fiber before signing.

THE TAKEAWAY
Our recommendation for San Leandro
If you can get AT&T fiber at your address, it’s a top-tier choice—symmetrical speeds up to 5000/5000 Mbps earn a standout 98/100 speed score, well above San Leandro’s 63 average, with the low latency fiber is known for. However, fiber only reaches about 70% of the city, so if you’re limited to AT&T’s copper/DSL (scores ranging from 3 to 52) or fixed wireless (39-58) service, expect slower, more basic performance and consider checking what other technologies are available at your specific address first. Since fiber availability varies block by block, confirm your exact address before deciding.
About AT&T
AT&T is an excellent choice in San Leandro if their fiber service is available at your address—nearly 70% of the area can access blazing-fast 5000 Mbps speeds (top 2% in the state). However, if fiber isn’t available at your location, you’ll likely be stuck with slower copper/DSL options (50-100 Mbps) that rank below average statewide and may struggle with modern streaming and remote work needs. Definitely check if the fiber is available at your specific address first, as that makes all the difference with AT&T.

Our recommendation for San Leandro
Xfinity brings cable internet to 98.5% of San Leandro, with a top plan reaching 2000↓/300↑ Mbps and an impressive Speed Score of 94/100—well above the city average of 63. If that top tier is available at your address, it’s a top-tier option delivering plenty of bandwidth for heavy streaming, gaming, and multiple connected devices. Even the widely available 1200↓/35↑ Mbps plan (Speed Score 89/100) is a solid, reliable choice, though its lower upload speeds are worth noting if you frequently upload large files or video conference. As a cable provider, Xfinity offers excellent real-world performance for most households.
About Xfinity

Their plans offer strong download speeds up to 2000 Mbps with speed scores of 89-94/100, putting them among the fastest options in California. The main limitation is upload speeds, especially on the 1200 Mbps plan which tops out at 35 Mbps, but overall this is a solid high-speed option for most households.

Fiber’s low latency and matching upload/download speeds make it excellent for everything from 4K streaming and gaming to video calls and large file uploads.

Unwired Ltd delivers licensed fixed wireless in San Leandro with 300↓/25↑ Mbps and a solid Speed Score of 79/100, comfortably above the city average of 63. Available to 87.3% of the city, this plan is a good, above-average option for streaming, video calls, and everyday browsing—especially in areas with limited wired coverage. Keep in mind that fixed wireless performance can vary with line-of-sight and weather, so if you need the lowest latency for heavy gaming or large uploads, it’s worth checking whether fiber or cable is available at your specific address.
About Unwired Ltd
Unwired Ltd offers fixed wireless internet with 300 Mbps download speeds to 87.3% of San Leandro, which provides good speeds (better than average in the state) with excellent coverage. Fixed wireless can be adequate for most households, though it may experience occasional weather-related disruptions or performance issues that cable and fiber don’t typically face. If fiber or cable internet is available at your address, you’ll likely get more reliable performance, but Unwired Ltd is a solid option where those technologies aren’t accessible.

Our recommendation for San Leandro
Verizon serves San Leandro through licensed fixed wireless, with its primary plan delivering 300↓/20↑ Mbps at a solid speed score of 78/100—above the city average of 63 and reachable at roughly 72% of addresses. If that top tier is available at your location, it’s a competitive choice for streaming, video calls, and everyday browsing, though fixed wireless can be more variable than fiber or cable during peak times or bad weather. Avoid the slower 50↓/5↑ Mbps plan (score 44/100) if you can, and since fiber and cable options also exist in this market, it’s worth checking which technologies reach your specific address before deciding.
About Verizon
Verizon covers most of San Leandro (74.5%) but primarily offers Licensed Fixed Wireless service, which can be adequate but isn’t as reliable as fiber or cable options. Their main plan delivers 300↓/20↑ Mbps with good speeds (78/100 score) and reaches 72% of the area, though the upload speeds are quite limited for modern needs like video calls and cloud backups. Before choosing Verizon, I’d recommend checking if other providers offer fiber or cable at your address, as those technologies typically provide more consistent performance.

Starlink brings satellite internet to 100% of San Leandro with download speeds up to 220 Mbps and 30 Mbps uploads, earning a speed score of 69/100—just below the city average of 63 and useful for households in hard-to-reach spots. That said, satellite service comes with higher latency than wired connections, which can affect video calls, gaming, and other real-time activities. Since San Leandro is well-served by faster ground-based technologies including fiber and cable, it’s worth checking what’s available at your specific address before committing—Starlink shines most as a reliable option where those wired connections don’t reach.
About Starlink
Starlink offers satellite internet coverage across 100% of San Leandro with speeds of 220 Mbps download and 30 Mbps upload, which scores 69/100 (below average for California). While these speeds can handle most everyday internet needs, satellite internet comes with inherent limitations like higher latency and weather sensitivity that make it less ideal for gaming or video calls. Before choosing Starlink, you should check if faster fiber or cable options are available at your address, as those technologies would provide more reliable performance for similar or lower prices.

T-Mobile covers 94.2% of San Leandro with fixed wireless service, though its availability varies by address—the faster 100↓/20↑ Mbps plan (Speed Score: 58/100) reaches about 48.5% of the city, while the slower 25↓/3↑ Mbps tier (Speed Score: 39/100) covers roughly 69.5%. Both scores fall below the city’s average of 63, and fixed wireless can be more variable than wired connections, so it’s best suited for lighter, everyday use. If you need faster or more consistent speeds, it’s worth checking what wired technologies like fiber or cable are available at your specific address before committing.
About T-Mobile
T-Mobile offers Fixed Wireless internet to most of San Leandro, but with below-average speeds that may struggle with modern household needs. Their fastest plan (100/20 Mbps) only reaches about half the city and scores just 58/100 for speed in California, while their more widely available 25/3 Mbps option scores even lower at 39/100. You should check if fiber or cable providers serve your address first, as T-Mobile’s wireless service would be best suited as a backup option or for light internet use only.

Etheric Networks delivers fixed wireless service in San Leandro with symmetrical-leaning speeds of 150↓/75↑ Mbps and a speed score of 70/100, which lands just above the city average of 63. Fixed wireless is a reasonable option for everyday browsing, streaming, and remote work, though it can be more susceptible to performance variability than wired connections. Since Etheric covers only about 38% of the city, check availability at your exact address—and if fiber or cable is offered where you live, those wired technologies typically provide more consistent speeds and lower latency for demanding use.
About Etheric Networks

About Viasat Inc
Viasat offers satellite internet with 100% coverage across San Leandro, but with a speed score of just 16/100, it’s one of the slower options in the area and comes with the typical satellite limitations like high latency.

Data Coverage for San Leandro
How We Calculate Speed Score
Our Speed Score is a state-level percentile ranking (0-100) that shows how a provider’s service compares to all other internet options available in your state.
The Formula:
We calculate a raw performance score using:
Technology Factor × (Download Speed × 70% + Upload Speed × 30%)
Technology Factors:
Not all connections are equal. We weight each technology based on real-world reliability and performance:
- Fiber: 100% – Fastest, most reliable technology
- Cable: 85% – High speeds, shared neighborhood bandwidth
- Fixed Wireless (Licensed): 70% – Dedicated spectrum, weather-dependent
- Copper/DSL: 65% – Distance-limited, aging infrastructure
- Fixed Wireless (Unlicensed): 60% – Shared spectrum, variable performance
- Satellite (LEO): 40% – Low-earth orbit (e.g., Starlink), higher latency
- Satellite (GEO): 15% – Geostationary orbit, significant latency
Percentile Ranking:
After calculating raw scores, we rank every service option in your state by geographic coverage (census blocks served). A score of 85 means this service performs better than 85% of all internet options available in your state.
Data Source: FCC National Broadband Map data, updated quarterly.
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

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.
