Quick Fact

Charter Communications merged with Time Warner Cable and Bright House Networks in 2016. Existing customers under Time Warner and Bright House have been transferred to Charter. Internet plans under the provider are now sold under the brand name “Charter Spectrum.”[1]

AT&T Internet and Charter Spectrum are two of the most common Internet options in the US, and often compete for the same customers.

Aside from their networks, the core differences boil down to comparing their TV options, supported equipment, and overall speeds.

Finally, there’s an outlier here: AT&T Fiber. This 100% fiber service offers some of the fastest upload and download speeds in the country at an extremely reasonable price point. It’s not for budget shoppers, but it’s our top pick if you’re in one of the few cities lucky enough to have the option. Unlike AT&T’s other plans, it has no data cap — good news for cord-cutters.[3]

Network Differences: Charter Spectrum Wins Out on Speed and Reliability

AT&T started as a phone provider, and their DSL network uses the same copper telephone cables that deliver landline phone service.

Charter Spectrum got their start as a cable TV provider, and their network still uses those coaxial cables originally installed for TV service.

AT&T’s DSL service is generally slower than Spectrum’s cable network. DSL usually delivers download speeds below 30 Mbps, although AT&T DSL uses advanced “Fiber to the Loop” network technology to deliver closer to 100 Mbps in some areas.

Spectrum, on the other hand, offers maximum speeds well over 100 Mbps in most areas. However, that speed often drops in the evening hours, when everyone else in the neighborhood starts maxing out the shared bandwidth with streaming services like Netflix.

A highway as a metaphor for bandwidth.
AT&T and Spectrum have both been adding more fiber to their “last mile” networks.

In both cases, AT&T and Charter have been building out fiber network “backbones” to speed up the network. This type of network is known as “Hybrid Fiber-Coaxial” or “Fiber to the Node.” Unlike DSL (telephone wires) or cable (coaxial TV cables), fiber-optic cables are much newer and use light to transmit data rather than frequencies transmitted over copper.

For most customers, data still travels over traditional copper DSL or cable networks for the “last mile” of the network between the provider and your house. Updating this “last mile” with fiber is very expensive, which is why 100% fiber networks like AT&T Fiber are rare. Once installed, however, they require little upkeep, which makes fiber service surprisingly affordable.

Equipment and Installation

The process of installing AT&T and Charter is very similar. You can either:

  • Have an installation tech come out and handle it for a small fee.
  • Order a self-install package and follow the instructions.
  • Purchase your own equipment and self-install.

Installation Considerations and Fees

Self-installation is advisable if you’d like to work around the standard installation fees charged by AT&T and Charter. Customers we talked to have also had success getting installation fees removed by simply asking politely on the phone — however, this can’t be guaranteed to work.

Self-installation is simple and the instructions that come with your leased modem/router device are easy to follow.

Modem and router leasing fees

If you’d like to save the $5–10/month fee for leased equipment, both AT&T and Charter allow you to purchase your own equipment instead.

This is ideal if you plan to use their service for multiple years, as the savings add up to hundreds of dollars. It is less ideal if you are a short-term resident, or if you simply don’t want to worry about setting up your own modem and router.

Each provider has their own list of specifications so far as what equipment is compatible with which services. Here’s a guide to modem and router options for AT&T, and here’s the Charter Spectrum page on modem and router options.

Buying your own equipment usually costs around $40–100 and you’re on the hook for replacement if it fails down the road, so it only makes sense for long-term customers who will recoup those savings.

AT&T Wins on TV Options

AT&T may not have the best Internet speeds in most areas, but they tip the scales for those of us who rely on solid, comprehensive TV service. They have two options:

  • AT&T Prism TV: Digital TV service delivered over the same network as AT&T Internet.
  • DirecTV:Satellite TV service, which was acquired by AT&T in 2014.

Of the two, DirecTV generally offers the most value, especially for sports fans. It also has nationwide availability, since it comes in via satellite. Anyone with room for a dish can get it. In the long run, AT&T will be packaging all their TV options into one product called “AT&T Entertainment.” For now, mobile customers are able to stream DirecTV channel offerings directly to all their devices free of data caps or fees — a glimpse of features to come.

Charter Spectrum’s TV service is a great budget choice when bundled with their Internet plans. However, you have to subscribe to one on their larger channel bundles in order to access premium channels like HBO, Showtime, Starz, and etc. Their sports bundles also come at a higher than average price in our experience, and sports fans who “want it all” will wind up paying a premium for it.

Deal Alert

As of August 8 2017, Charter Spectrum is offering to buy out your contract with another Internet provider to earn your service. This is a huge deal for customers locked in with an inferior cable company by steep early termination fees.

AT&T U-verse vs Charter Spectrum: Bundle Plans

If you want TV and/or phone service along with your Internet, getting a bundled deal from one provider is a no-brainer. The final rate you get is rarely as attractive as it looks up-front, but it’s always cheaper than getting services separate, not to mention less billing headache.

As a rule of thumb, Charter Spectrum is by far the best option for Internet-only customers, since they have unlimited data, faster than average speeds, and contract-free service.

AT&T has cheaper bundles in most areas, but it’s best for TV users since the Internet is generally less zippy. (At least, outside their fiber service areas.)

AT&T U-verse vs Charter Spectrum: Charter Wins for Internet Service Quality, AT&T Wins for TV Options

A highway as a metaphor for bandwidth.
Choose Spectrum if you value Internet speed, and AT&T if you value TV options.

The bottom line with AT&T and Charter is this:

AT&T is best for customers who want “okay” Internet at a great price and spend more time watching TV than surfing the web.

Charter Spectrum is best for customers who want excellent Internet speeds and would rather “cut the cord” from cable.

Our team’s opinion is that Charter’s unlimited data and contract-free plans offer the best value for the average home.
