What is the best internet provider in Madison?

AT&T Fiber is the best internet service provider in Madison, thanks to its fast speeds as high as 5000Mbps, widespread availability and straightforward pricing. Spectrum is another excellent choice with affordable plans and reliable service throughout Madison. You can get 300Mbps for $40 a month on Spectrum, but prices increase significantly after a year. Wireless internet from AT&T, T-Mobile and Verizon is also available throughout the city. These are great options if you're able to bundle with one of the provider's cellphone plans.

All available Madison residential internet providers

• AT&T Internet: AT&T's fiber game is strong in Madison but doesn't reach every part of town. AT&T Internet, the company's old-school DSL offering, covers more ground. It costs $55 a month for whatever speed you can get at your location, typically up to 300Mbps, depending on your location. The price-to-speed ratio won't be appealing if you have a faster and cheaper option.
• Verizon 5G Home Internet: With speeds up to 1,000Mbps in some parts of the country, Verizon is working hard to convince buyers that fixed wireless is the way to go for home internet. The company's coverage map shows a mix of its latest 5G networks alongside slower 4G LTE coverage across Madison. The area east of Lake Mendota and Lake Monona has the widest 5G Ultra Wideband coverage. Typical Verizon home internet speeds in Madison will range from 100 to 300Mbps starting at $60 a month. The biggest challenge is finding an open slot, so T-Mobile edged Verizon as our pick for Madison's best fixed wireless provider.
• TDS Telecom: TDS covers a small portion of Madison proper, but it's well worth mentioning for those in communities around Madison. TDS delivers fiber to places like Middleton, Monona and Waunakee. Prices start at $50 a month (for the first two years) for a 300Mbps plan. On the fast end, TDS has a 1,000Mbps plan for $90 a month. You have the option to rent a router for $12 a month. There's a $50 installation fee, but a good chance you can get that waived. Be sure to check out the TDS price-for-life plans. They're more expensive over the first two years but will keep your price locked in for the long haul. 
• US Cellular: US Cellular is a sister company of TDS Telecom. It offers fixed wireless internet in Madison for $50 a month with an autopay discount. That pricing puts it in contention with T-Mobile and Verizon's home internet plans. Some of US Cellular's service areas can get up to 300Mbps speeds, but your mileage could vary considerably depending on your location. The biggest turn-off is that US Cellular will throttle your speeds after 600GB of high-speed data with its Home Internet Everywhere plan. After that, you'll get bumped down to a painfully slow 1.5Mbps. Keep an eye on the plan terms. US Cellular may offer to cover equipment costs via a credit spread over a 36-month installment contract. It's all a bit confusing, so you'll likely do better with another ISP with simpler or faster plans with no throttling.   
• Satellite internet: Rural residents with few internet options should check into satellite providers Starlink, Viasat and Hughesnet. These likely won't be your first choice if you live in town and have access to fiber, cable, or fixed wireless from T-Mobile or Verizon. If you're big on traveling (let's say you're heading south for the winter) and still need to stay connected, check into Starlink's on-the-go plan. It's pricey, but it will help you stay online when you've taken on the role of a digital nomad.

Depending on your location, service from the likes of T-Mobile, Verizon or US Cellular may be fast or slow. Spectrum’s cable plans cover a lot of ground from 300Mbps on up to near-gig speeds. AT&T Fiber brings the heat with multi-gigabit fiber plans, although many people will opt to save money and stick with 1,000Mbps or below. If you’re eyeing that speed level, see if TDS services your address with its 1,000Mbps plan for $90 a month.

How CNET chose the best internet providers in Madison

Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it's impractical to personally test every internet service provider in a given city. What's our approach? For starters, we tap into a proprietary database of pricing, availability and speed information that draws from our own historical ISP data, partner data and mapping information from the Federal Communications Commission at FCC.gov. 

It doesn’t end there: We go to the FCC’s website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP's service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of publication. 

Once we have this localized information, we ask three main questions: 

• Does the provider offer access to reasonably fast internet speeds? 
• Do customers get decent value for what they're paying? 
• Are customers happy with their service? 

The answer to those questions is often layered and complex, but the providers who come closest to “yes” on all three are the ones we recommend. When selecting the cheapest internet service, we look for the plans with the lowest monthly fee, although we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds and consider real-world speed data from sources like Ookla and FCC reports.

What’s the final word on internet providers in Madison?

One of the biggest challenges with picking an ISP in Madison is the patchwork nature of coverage from the leading providers. Yes, AT&T Fiber is fast, but what if it doesn’t service your address? Your next option will likely be Spectrum for a cable connection but don’t count out fixed wireless from Verizon or T-Mobile. If you’re in a good location for one of those, you might find you’re happy with the speeds and even happier with the phone bundle discount. Finally, TDS Telecom is worth a look for residents of surrounding communities who want fast, reliable fiber.
