you may change names, but apparently, you can’t change problems. If you’re a New Yorker unhappy with the internet service provided by Charter Communications (which bought Time Warner Cable, rebranding the company as Spectrum), know that you’re not alone. Far from it, in fact. On Wednesday, New York Attorney General Eric Schneiderman filed a lawsuit accusing Spectrum of underdelivering when it comes to internet speeds for its customers.

Considering that services affected by the slow speeds are crowd-pleasers like Netflix, Facebook, and gaming platforms, it’s no wonder that consumers and officials alike are none too pleased about Spectrum’s services. In fact, Schneiderman noted at a news conference that Spectrum’s Wi-Fi speeds were a full 80 percent slower than advertised. Speed test results suggested that 300Mbps plans were only delivering speeds of 85Mbps.

“Reliable internet service is not a luxury, it is a necessity,” said Schneiderman. The attorney also drew attention to an internal email in which Spectrum engineers noted that their modems were incapable of supporting speeds as advertised, but made no changes to their practices.

Specifically, the investigation found that when Netflix and Riot Games agreed to pay Spectrum more money, performance to the sites actually improved.Schneiderman concluded: “The allegations in today’s lawsuit confirm what millions of New Yorkers have long suspected — Spectrum-Time Warner Cable has been ripping you off.”

For its part, Charter has said that it is “disappointed” by the lawsuit because many of the accusations took place before the company acquired Time Warner Cable. “Charter has already made substantial investments in the interest of upgrading the Time Warner Cable systems and delivering the best possible experience to customers,” the company said.
