Consumer Reports wants the Federal Communications Commission to take a closer look at whether Internet service providers are complying with a US law that prohibits them from charging hardware rental fees when customers use their own equipment. In a filing submitted to the FCC this week, Consumer Reports said it asked members about their Internet bills and got over 350 responses, with some suggesting violations of either the letter or spirit of the law.

"Some contain allegations that the law is being violated, whereas others state the new statute is being respected. Many more stories suggest that ISPs dissuade consumers from using their own equipment, typically by refusing to troubleshoot any service disruptions if consumers opt not to rent the ISP's devices. Such practices result in de facto situations where consumers feel pressured or forced to rent equipment that they would prefer to own instead," Consumer Reports told the FCC.
