Cablevision Systems has filed a lawsuit against Verizon Communications in a battle over providing WiFi to consumers. Reuters reports that the suit, filed Thursday, [Jan. 29, 2015] accuses Verizon of false advertising with TV, radio and Internet messages that claim Verizon offers the fastest WiFi service available.

“The complaint, filed with the U.S. District Court in Central Islip, New York, accuses Verizon of basing its ‘fastest WiFi available’ claim on new network routers it has been installing for up to $199.99, despite knowing that Cablevision offers the same routers for its Optimum network, free of charge,” the story reports.

Reuters also notes: “Cablevision also called the advertising an effort to stymie its launch of a low-cost ‘Freewheel’ phone that could cut into sales by Verizon and other cellular service providers.”

Verizon is the largest U.S. wireless company.

The story adds, “Verizon rejected Cablevision’s allegations. ‘This is a boldface ploy to promote Cablevision’s latest wireless gambit,’ Verizon said in a statement. ‘A third party has tested and validated the FiOS Quantum Gateway router. It offers the fastest in-home Wi-Fi available from any provider.’
