Best Internet Providers in Idaho Falls, Idaho

What is the best internet provider in Idaho Falls?

CNET’s top pick for internet in Idaho Falls is ConnectFast, offering 1,000Mbps symmetrical speeds for just $40 per month. However, keep in mind that this price doesn’t include the $25 Idaho Falls Fiber infrastructure fee. Even with that extra cost, the overall value remains impressive compared to other broadband options in the area.

Idaho Falls residents also benefit from the city-owned Idaho Falls Fiber Network, a public-private partnership that provides multiple ISP choices. While the $25 monthly infrastructure fee applies regardless of provider, plans start as low as $40 per month, making high-speed internet widely accessible. That said, not all ISPs on the network are created equal—according to a Reddit user claiming to work in local fiber installation, Fybercom ranks as the least reliable option among the six available providers.

Looking for the cheapest internet? Sparklight offers the lowest starting price in Idaho Falls, with plans at $36 per month for 100Mbps download and 20Mbps upload speeds. Alternatively, T-Mobile Home Internet delivers fixed wireless service for $50 per month, with speeds reaching 245Mbps, plus unlimited data and included equipment.

For those prioritizing speed, Quantum Fiber is the one of the fastest ISPs in Idaho Falls, with plans offering up to 1,000Mbps downloads and 1,000Mbps uploads for $75 per month. Unlike ISPs on the Idaho Falls Fiber Network, Quantum Fiber doesn’t require the additional $25 infrastructure fee. A lower-end 500Mbps plan is also available for $50 per month, making it a strong contender for high-performance connectivity.

What’s a good internet speed?

Most internet connection plans can now handle basic productivity and communication tasks. If you're looking for an internet plan that can accommodate videoconferencing, streaming video or gaming, you'll have a better experience with a more robust connection. Here's an overview of the recommended minimum download speeds for various applications, according to the Federal Communications Commission. Note that these are only guidelines and that internet speed, service and performance vary by connection type, provider and address.

For more information, refer to our guide on how much internet speed you really need.

• 0 to 5Mbps allows you to tackle the basics: browsing the internet, sending and receiving email and streaming low-quality video.
• 5 to 40Mbps gives you higher-quality video streaming and videoconferencing.
• 40 to 100Mbps should give one person sufficient bandwidth to satisfy the demands of modern telecommuting, video streaming and online gaming. 
• 100 to 500Mbps allows one to two people to simultaneously engage in high-bandwidth activities like videoconferencing, streaming and online gaming. 
• 500 to 1,000Mbps allows three or more people to engage in high-bandwidth activities at the same time.

How CNET chose the best internet providers in Idaho Falls

Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it’s impractical to personally test every ISP in a given city. What’s our approach? We start by researching the pricing, availability and speed information drawing on our own historical ISP data, the provider sites 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 the time of publication.

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

1. Does the provider offer access to reasonably fast internet speeds?
2. Do customers get decent value for what they’re paying?
3. 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 it comes to selecting the cheapest internet service, we look for the plans with the lowest monthly fee, though 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 also take into account real-world speed data from sources like Ookla and FCC reports.
