CenturyLink (or Lumen) and Spectrum overlap in nearly a dozen states. Both offer home fiber internet to some degree, but CenturyLink is mostly a DSL provider, while Spectrum offers cable internet.

At first glance, CenturyLink’s fiber has the best megabits-per-dollar value for the long term. However, Spectrum fares better than CenturyLink in our latest customer satisfaction survey, surpassing it in speed, reliability, customer support, and overall satisfaction. Pricing is Spectrum’s only real setback, as it increases your rate after 12 or 24 months—CenturyLink doesn’t.

CenturyLink’s fiber internet is a good deal when you compare it to Spectrum. With the 500Mbps plan, you get plenty of symmetrical speed at a low cost—indefinitely, in fact. Spectrum’s similar Ultra plan sets you back up to $70 per month during the first two years, and then the price increases by around $25 after that. Even if you manage to find Spectrum’s fiber internet, CenturyLink is still a better long-term deal.

But keep in mind that CenturyLink ranks far lower than Spectrum in nearly every category in our customer satisfaction survey. So, while you may be saving money with CenturyLink in the long term, it doesn’t score well in speed, reliability, customer service, and overall satisfaction based on customer feedback. It’s something to consider when choosing between CenturyLink and Spectrum.

Spectrum competes in nearly a dozen states where CenturyLink offers fiber and DSL internet. Spectrum is mostly uncontested by CenturyLink on the Eastern side of the U.S., except for Florida, where the two duke it out for your hard-earned cash throughout most of the state. Like most telecoms and internet providers, CenturyLink is swapping out old copper telephone lines with new fiber ones, while Spectrum is simply laying down new fiber and keeping its “last mile” cable TV lines intact.

But when we look at how the two price their internet, CenturyLink is the better deal for the long term. CenturyLink will always have the upper hand until Spectrum drops its post-promotional price hikes—even if it does have a new two-year price guarantee on its 500Mbps and 1,000Mbps plans. Until then, Spectrum will continue to have a low pricing satisfaction score in our annual survey.

As the table shows, CenturyLink has a higher pro install cost of the two, but it doesn’t charge you to self-install internet equipment. Keep in mind that, in both cases, you can’t self-install new internet—this must be done by a CenturyLink or Spectrum professional. Self-installs are for existing DSL, cable, and fiber connections coming into your home or office.

Spectrum’s WiFi charge applies to the gateways and standalone routers it distributes to customers. If you want to use a store-bought standalone router or mesh system and save $7 per month, call Spectrum to disable WiFi in the gateway or take the standalone router to a local Spectrum store.

* Rating based on a five (5) point system used in our customer satisfaction survey. Higher is better.

Spectrum ranks higher than CenturyLink in overall satisfaction in our latest customer satisfaction survey, placing seventh out of 15 internet providers versus CenturyLink ranking eleventh. Spectrum ranks better in every category, actually, except in price, where CenturyLink places fifth, followed by Spectrum ranking eighth. Spectrum raises prices up to $25 per month after the first 12 months—CenturyLink doesn’t.

According to our survey, CenturyLink’s weakest link is in speed satisfaction, placing it at the bottom out of 15 internet providers. Spectrum did fairly well in that category, falling behind cable internet rivals Cox and Xfinity. All in all, Spectrum’s cable or fiber internet is your best bet if you can get it based on customer feedback alone.

CenturyLink offers just one TV and internet bundle with its fiber internet service. All other bundles are based on its DSL internet, and the one listed above is the cheapest that you can get. All bundles rely on DIRECTV’s satellite TV service, but there’s no discounted pricing when you bundle.

Spectrum doesn’t offer the traditional TV and internet bundle at a discount. Instead, you can pair its TV Select service with any one of its three cable internet plans. Both services have discounted pricing for the first 12 months, but all premium channels like Max and Paramount+ with SHOWTIME® are extra. Plus, you’ll see a broadcast TV service charge for up to $20 per month that’s not included in the discounted pricing.

CenturyLink and Spectrum offer fiber internet, although Spectrum’s fiber isn’t as widely known as CenturyLink’s. Both have gigabit-class plans with symmetrical speeds, while Spectrum has a few more slower speed options than CenurtyLink.

Spectrum’s cable internet is more widespread than CenturyLink’s fiber. Technically, it’s backed by fiber—coax cable is used in the “last mile” to your home to keep costs low. Cable internet generally doesn’t offer symmetrical speeds like fiber, but that’s slowly changing. Spectrum currently offers symmetrical cable speeds in two markets and plans to expand the technology into all of its areas by 2026, along with 10Gbps downloads.

CenturyLink’s older DSL internet uses existing telephone lines and doesn’t go above 140Mbps in download speed. The company is currently swapping these lines out with faster, newer fiber ones.

While Spectrum does not have an internet data cap, its acceptable use policy prohibits “excessive use of bandwidth that in Charter’s sole opinion, places an unusually large burden on the network or goes above normal usage.”

CenturyLink used to have a 1TB data cap on most of its residential internet plans, but now neither its fiber plan nor its DSL plan have any caps.

Spectrum encourages new customers to opt for the self-install kit over a pro installation. However, Spectrum will send a technician out for completely new installs, or if you need a modem moved, rewiring, and so on. The WiFi Pod setup is a separate installation fee.

CenturyLink also has professional and self-installation options. If you go with self-installation, CenturyLink charges a $50 shipping and handling fee to send the kit, so going the DIY route doesn’t save you as much money as it does with Spectrum. But it’s still a good alternative to waiting around all day for the technician to show up—as long as you know what you’re doing.

Professional installation for CenturyLink internet costs up to $99, depending on the package and where you live. But some internet plans get free installation. The qualifications for free installation vary by plan and location, so ask your CenturyLink representative about it when you sign up.

Spectrum’s cable and fiber internet compete with CenturyLink’s DSL and fiber internet in 11 states, including Florida, Oregon, Minnesota, Washington, and Wisconsin.

The largest chunk of Spectrum’s network resides on the eastern side of the nation. It also commands some areas in Texas and California and a few places on the west coast. But overall, Spectrum has far more cable than fiber internet, although you’ll likely see a higher ratio of fiber installs in Minnesota, North Carolina, New York, and Ohio than in other states—for now, at least.

CenturyLink has a large footprint in Florida, Colorado, Iowa, Minnesota, Oregon, and Washington. It’s also scattered throughout the Central, Mountain, and Pacific time zones, offering mostly DSL and some fiber internet. CenturyLink is currently swapping out copper lines with fiber, so it has a higher copper-vs-fiber ratio than Spectrum.

CenturyLink and Spectrum overlap in nearly a dozen states, so you’ll likely see Spectrum’s cable internet as an alternative to CenturyLink’s DSL and fiber internet. Spectrum also has fiber, but it only clashes with CenturyLink’s fiber in Florida and a few other spots.

Price-wise, CenturyLink’s fiber internet is the better megabit-per-dollar value for the long term. Unlike Spectrum, your rates don’t increase after the first or second year. CenturyLink’s DSL internet, however, is expensive for the little speeds you get.

On the flip side, customers rate Spectrum better than CenturyLink in terms of overall satisfaction, speed, reliability, and customer support. In that respect, you kind of get what you pay for: better service for a slightly higher price.

So, it all boils down to what’s best for you if both providers are in your area. But keep in mind Spectrum expects to deliver fiber-like speeds across its cable connections in the coming years, so the CenturyLink vs. Spectrum fight will be a whole different ballgame once that happens.
