They flip flop between giving you a modem and charging you rent for it. They hope you won't notice it on your bill. I rented one for three days, got charged 1/10 month rent for it. The first thing I did when I got the modem home was order a proper replacement online. Oddly (to nobody) the cable company's modem MAC address was immediately accepted to my account but the replacement took an hour phone call to India to get working.
