Find internet providers in Old Greenwich, CT
Find internet offered in Old Greenwich, CT – easily compare options from multiple providers to find the plan that best fits your needs.
FindBetterInternet was created by two guys with years of first-hand industry experience selling internet services online. Frankly, what we found left a lot to be desired. Internet providers can pay for their listings to be placed higher up the page, cookies can be captured, and your data can be shared for banner ads that stalk your online profile for the next week. We built FindBetterInternet to be different.
Our methodology translates the complex treasure trove of 115m locations on the FCC Broadband Map into one simple resource. We layer on pricing to help you sift through what’s good value.
We hope this is helpful for you and appreciate all the community’s support with this project. If you find it helpful, we do make a commission if you buy internet from a link on our address-check page. We pour that back into maintaining the site.
Every price and coverage figure on this site traces back to FCC Broadband Data Collection filings (the National Broadband Map); here’s exactly how we do it.

Satellite internet can handle everyday browsing and streaming, but its higher latency may make video calls, gaming, and other real-time uses less responsive. Starlink’s plans range from up to 100 Mbps download and 25 Mbps upload for $55/mo to up to 400 Mbps download and 30 Mbps upload for $130/mo, with every plan carrying a Speed Score of 59/100, below Old Greenwich’s city average of 64. The 100 Mbps plan is available to 100.0% of the city, but check which connection types are available at your specific address before choosing, especially if low latency matters.
About Starlink
Satellite internet is available across 100.0% of Old Greenwich, with Starlink plans offering up to 400 Mbps download and up to 30 Mbps upload, though higher latency can make gaming and some video calls less responsive.

THE TAKEAWAY
Our recommendation for Old Greenwich
At $94.99/mo for the first 12 months, then $119.99/mo, HughesNet’s Fusion plan buys up to 100 Mbps download and 5 Mbps upload, but its 30/100 Speed Score is below Old Greenwich’s city average of 64. Satellite’s higher latency and limited performance make it a weaker choice for demanding use, so check what other technologies are available at your address before choosing, even though Fusion is available to 100.0% of the city.
About HughesNet
At $94.99/mo for the first 12 months, then $119.99/mo, HughesNet’s Fusion plan offers up to 100 Mbps down and 5 Mbps up, while Select costs $49.99/mo for the first 12 months, then $74.99/mo, for up to 50 Mbps down and 5 Mbps up. All three satellite plans reach 100.0% of Old Greenwich, but their 30/100 or 12/100 speed scores and satellite latency make them better for basic use than demanding gaming, video calls, or several simultaneous streams. Check your address for fiber or cable before choosing HughesNet, since it is best treated as a fallback where faster wired service is unavailable.

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
Our proprietary score weights technology type (fiber=100%, cable=85%, etc.) with download (70%) and upload (30%) speeds, ranked as a state percentile.
Coverage Calculation
Provider coverage shows what percentage of census blocks in Old Greenwich report service availability from each provider.
Data Coverage for Old Greenwich
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 twice a year.
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.
