For most of the last twenty years, a New Hampshire household had one real choice: Comcast, now Xfinity, and whatever the old phone line could manage. That changed when Consolidated Communications started stringing fiber under the Fidium name along the poles it inherited from the Bell days. Today Fidium and Xfinity each reach about seven in ten Granite State addresses, and in Manchester, Nashua and Concord they overlap on most streets. It is the closest thing New Hampshire has had to a fair fight.
Our pick for most New Hampshire homes is Fidium Fiber, with a condition. We rank by availability first and technology second, fiber ahead of cable, cable ahead of 5G, satellite last. Fidium reaches slightly more addresses than Xfinity and it is fiber where the new lines have gone in. The condition: some Fidium addresses still get Consolidated's older copper DSL, a worse product than Xfinity cable. If Fidium's check comes back fiber, take it. If it comes back DSL, take Xfinity.
Which internet providers cover most of New Hampshire?
New Hampshire is a small, well-wired state.[1] Cable passes almost nine in ten locations, fiber a bit over six in ten, and nearly every address has some wired option. Licensed 5G reaches under a third, hemmed in by hills and tree cover, so this is one of the few states where the wireless carriers are not a serious statewide rival to the wires.
| Provider | Type | Where it's available | Contract |
|---|---|---|---|
| Fidium Fiber (Consolidated) | Fiber where built, older DSL elsewhere | Across most of New Hampshire | Not stated |
| Xfinity | Cable | Across most of New Hampshire | No annual contract[2] |
| T-Mobile 5G Home Internet | 5G fixed wireless | Across most of New Hampshire | No annual contract[3] |
| Verizon 5G Home Internet | 5G fixed wireless | In many areas | No annual contract[4] |
| AT&T Internet Air | 5G fixed wireless | In many areas | No annual contract[5] |
| Breezeline | Cable | In some areas (Seacoast, Concord, Rochester) | Not stated[6] |
| Spectrum | Cable | In some areas (Keene and the southwest) | Not stated |
Two smaller names matter in specific places: New Hampshire Electric Cooperative in its rural territory, and TDS Telecom in a handful of towns. Starlink, Hughesnet and Viasat are available almost everywhere, mainly useful in the North Country.
What is the best internet in Manchester, Nashua and Concord?
Manchester is a fiber city. Fidium is on more than eight in ten addresses and Xfinity on every one, so most residents genuinely choose between fiber and cable. T-Mobile's 5G reaches a strong share of the city too. Searches for the cheapest internet in Manchester usually end at Xfinity's 300 Mbps plan, $45 a month for new customers with autopay and paperless billing,[2] unless Fidium is running a promotion on your street.
Nashua is nearly identical: Xfinity everywhere, Fidium on eight in ten addresses, fiber reaching six in ten homes. Proximity to Massachusetts doesn't bring Fios across the border; Verizon here means 5G Home, not fiber.
Concord has a three-way contest. Xfinity and Fidium overlap across most of the capital, and Breezeline's cable reaches seven in ten homes too. Concord's fiber share is the best of the three big cities.
Dover and Rochester on the Seacoast lean on Breezeline; Rochester in particular is a Breezeline town, with Xfinity and Fidium behind it. Keene, in the southwest corner, is the state's one Spectrum market, with the highest fiber share of any of them.
Is 5G home internet a good choice in New Hampshire?
Not usually as a first choice. Statewide, licensed 5G home internet reaches fewer than one in three locations, the lowest share of any technology here. The big cities are better: T-Mobile covers most of Manchester and Nashua, and its Rely plan at $50 a month with AutoPay and no annual contract[3] suits a renter who wants to skip a cable install. Verizon 5G Home is $35 a month with a Verizon phone plan,[4] and AT&T Internet Air has unlimited data and no annual contract.[5]
Outside the Merrimack Valley the coverage thins quickly. In Rochester or Keene, fewer than one in four addresses can get licensed 5G. In the Lakes Region and the North Country, assume you can't until an address check says otherwise.
How do I tell whether Fidium is fiber or DSL at my address?
This is the most useful thing a New Hampshire shopper can learn, and a coverage map won't tell you. Consolidated has been overbuilding its old copper telephone network with fiber town by town, and the FCC counts both under the same company. On an address check, fiber plans show symmetrical speeds, the same number up and down. DSL plans show a much slower upload.
If you see symmetrical speeds, Fidium is our pick and you can stop shopping. If you see DSL speeds, go to Xfinity, which sells 300 Mbps for $45 a month with no annual contract and unlimited data,[2] or Breezeline where it exists, with a 500 Mbps online offer at $40 a month for new customers.[6] We could not retrieve Fidium's own plan terms, so confirm contract and pricing with the company.
What should I ask before I sign up?
- What is the rate after the promotional period ends?
- Is there a contract or term commitment, and what is the early-exit fee?
- Is there a data cap or a slowdown threshold? Xfinity and the 5G carriers say no.
- Is the gateway included, or billed as a monthly rental?
- How soon can you install, and is there a charge for the visit?
- What happens at renewal: automatic step-up, or a new quote?
Frequently asked questions
Who has the best internet in New Hampshire?
Fidium, where its fiber is built, on our availability-plus-technology basis. It reaches most of the state and offers fiber across much of Manchester, Nashua and Concord. Xfinity is the pick where Fidium only offers DSL.
What is the fastest internet in New Hampshire?
Fidium fiber in the towns where it has been built; the symmetrical upload is the difference. Xfinity cable is the fastest option on the roughly four in ten addresses without fiber.
Is Xfinity available in New Hampshire?
Yes, across most of the state, including every address in Manchester and Nashua. Its 300 Mbps plan is $45 a month for new customers with autopay and paperless billing, no annual contract, unlimited data.[2]
What is the cheapest internet in New Hampshire?
Verizon 5G Home at $35 a month if you already have a Verizon phone plan.[4] Among wired providers, Breezeline's 500 Mbps online offer at $40 a month[6] and Xfinity's 300 Mbps plan at $45 a month[2] are the published entry points.
