Optimum is the best overall, with fiber speeds up to 8,000/8,000 Mbps reaching about 96% of the city. Frontier is the safe fallback where Optimum fiber does not reach, offering mostly fiber with speeds up to 7,000/7,000 Mbps and an overall footprint of about 78% of the city.

In Old Greenwich Village, the local picture strongly favors Optimum, covering about 92% of the ZIP with fiber, while Frontier reaches about 3% and Starlink about 5%. The Shorelands can still vary by street, so do not assume the citywide picture guarantees the same technology at every address. Optimum’s cable network is also broadly available, reaching about 98% of the city with speeds up to 940 Mbps, though fiber is the standout when available. Verizon is worth checking where its fiber reaches, covering about 22% of the city with speeds up to 940/880 Mbps. T-Mobile and AT&T offer more limited fixed wireless options, with speeds up to 100/20 Mbps in their respective covered areas. Coverage can change street by street, so confirm the exact address before choosing.

THE TAKEAWAY

Our recommendation for Old Greenwich

With a headline Speed Score of 87/100, Frontier’s Fiber 7 Gig plan offers up to 7,000 Mbps both ways, enough for heavy streaming, gaming, large downloads, and many connected devices at once.

Fiber 7 Gig is available to about 77% of Old Greenwich, so confirm that this address-specific fiber tier reaches your home before choosing it.

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 Frontier

THE TAKEAWAY

Our recommendation for Old Greenwich

Verizon’s fiber connection is a strong choice for streaming, gaming, and multiple users, with the 1 Gig plan offering up to 940 Mbps download and 880 Mbps upload for a 64/100 Speed Score, above Old Greenwich’s city average of 51. Fiber plans are available to about 22% of the city, so the best performance may depend on whether fiber reaches your address; Verizon also offers 5G Home with up to 300 Mbps download and 75 Mbps upload where available.

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 Verizon

Verizon’s fiber plans offer excellent everyday performance, including symmetrical speeds of up to 940 Mbps, 500 Mbps, or 300 Mbps for homes that can get them. Fiber availability is address-dependent and shown at about 22% of Old Greenwich, while Verizon’s 5G Home option reaches about 16% and offers up to 300 Mbps download and 75 Mbps upload, so check your address for fiber first because the fixed-wireless alternative can be more variable for demanding modern use.

THE TAKEAWAY

Our recommendation for Old Greenwich

T-Mobile is a practical fit for households seeking affordable home internet for streaming, browsing, and everyday work, with plans offering up to 400 Mbps download and 50 Mbps upload for $35 per month or up to 500 Mbps download and 60 Mbps upload. Its fixed wireless service earns a 64/100 Speed Score, above Old Greenwich’s city average of 51, but performance can be less consistent than wired connections. The 500 Mbps plans are available to about 40% of the city, so check your address and compare other available technologies before choosing.

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 T-Mobile

T-Mobile is a reasonable fit for smaller households, remote workers, and everyday users who can get its fixed wireless service and are comfortable with adequate, rather than top-tier, performance. Its plans offer up to 500 Mbps download and 60 Mbps upload, but the technology has a below-average 64/100 Speed Score and the 500 Mbps options are available to about 40% of Old Greenwich, so availability and wireless performance are address-dependent. Check your address carefully, especially if you need consistently strong service for multiple heavy users, and compare faster cable or fiber options first.

THE TAKEAWAY

Our recommendation for Old Greenwich

AT&T Internet Air costs $40 per month for 12 months and offers up to 300 Mbps download and 30 Mbps upload, providing reasonable value for everyday use. Its 59/100 Speed Score is above Old Greenwich’s city average of 51, but fixed wireless can be less consistent than wired connections, so consider checking other providers first for heavier or latency-sensitive use. Availability depends on your specific address, since this plan reaches only 24.4% of the city.

About AT&T

THE TAKEAWAY

Our recommendation for Old Greenwich

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 22/100 Speed Score is below Old Greenwich’s city average of 51. Satellite offers limited performance compared with alternatives, so consider checking what other technologies are available at your address before choosing HughesNet.

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 service has below-average performance and may not be the best value for demanding modern use. All three plans are available to about 100% of Old Greenwich, though you should check your address for faster fiber or cable options first, since satellite can be a limited fallback.

How We Analyze Internet in Old Greenwich

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 Old Greenwich report service availability from each provider.

Data Coverage for Old Greenwich

ZIP Codes Analyzed:
06870
Census Tracts: 5 tracts
Census Blocks: 201 blocks analyzed

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.

Note: Actual performance depends on your specific location, network congestion, and equipment quality.
