The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 63% of the city, while its overall footprint is about 100%. If Fidium Fiber reaches your address, it is the faster choice, with fiber speeds up to 2,000/2,000 Mbps reaching about 29% of the city. Where Xfinity does not reach, Consolidated Communications is the broadest backup, mostly DSL, with an overall footprint of about 68% and a fastest common DSL tier of up to 10 Mbps reaching about 29%.
In North Londonderry, Xfinity is the leading local option at about 35% of the ZIP, while Fidium Fiber reaches about 28% with fiber. That makes North Londonderry particularly worth checking for fiber, though street-level availability can still change quickly. South Londonderry deserves the same address-level check, since the city-wide picture does not guarantee service at every home. T-Mobile, Verizon, and AT&T provide additional fixed wireless choices where available, but their coverage and speeds vary considerably by address. Confirm the exact address before ordering, especially if you are hoping for Fidium Fiber or the fastest Xfinity tier.

THE TAKEAWAY
Our recommendation for Londonderry
Up to 2000 Mbps both ways, the 2 Gig Power Users fiber plan can comfortably support busy households, 4K streaming, gaming, and large downloads, earning an excellent 86/100 Speed Score that is above Londonderry’s city average of 46. Fiber availability for this plan is limited to about 29% of the city, so check your address before choosing it, but where available, Fidium Fiber is a top-tier option.

About Fidium Fiber
Up to 2000 Mbps both ways on Fidium Fiber can comfortably handle large households, 4K streaming, gaming, video calls, and heavy downloads at the same time. The 2 Gig plan is an excellent option but reaches only about 29% of Londonderry, while the up to 1000 Mbps and 300 Mbps fiber plans are available to 80.1% of the city, so your address determines which fast fiber option you can order.

THE TAKEAWAY
Our recommendation for Londonderry
Consolidated Communications is a limited-performance choice in Londonderry compared with available alternatives, with a headline Speed Score of 1/100 versus the city average of 46. Its DSL plans reach only basic to moderate speeds, from up to 10/1 Mbps on BASIC, available to about 29% of the city, to up to 50/10 Mbps on ADVANCED, with a plan Speed Score of 15/100 and availability to about 3% of the city. Because availability varies by address, check whether the faster DSL plan reaches your home, and consider checking other providers first.
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 Consolidated Communications
Consolidated Communications is mainly an adequate backup option in Londonderry, since its DSL plans top out at up to 50 Mbps download and 10 Mbps upload, with the BASIC plan offering only up to 10 Mbps download and 1 Mbps upload. The faster ADVANCED plan is available to about 3% of the city, while BASIC reaches about 29%, so coverage is address-dependent and these slower options may not be sufficient for busy households or modern internet needs. Check your address for faster service from another provider first.

Satellite service can support streaming, browsing, and video calls, but its higher latency may be noticeable for gaming and other real-time use. Starlink’s Residential Max plan offers up to 400 Mbps download and 40 Mbps upload for $130 per month, with a Speed Score of 71/100, above Londonderry’s city average of 46. That plan is available to 100.0% of the city, though address-level confirmation is still important, and consumers who need lower latency should check what other connection types are available at their address.

About Starlink
Satellite internet gives Starlink broad reach, with service shown across 100.0% of Londonderry, and its Residential Max plan offers up to 400 Mbps down and 40 Mbps up for demanding everyday use, though satellite latency can affect gaming and video calls. It is a useful option where wired service is unavailable, but check your address for fiber or cable first, since those technologies generally provide a better experience for modern online needs.

About HughesNet
Starting at $39.99 per month, HughesNet offers up to 25 Mbps with Lite, while $49.99 Select provides up to 50 Mbps and $94.99 Fusion provides up to 100 Mbps, so the higher prices mainly buy more speed rather than top-tier performance. All three satellite plans are available to 100.0% of Londonderry, but satellite internet can have high latency and limited capacity, so check whether faster cable or fiber service is available at your address before choosing HughesNet.

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