Motorola SURFboard SB6121 DOCSIS 3.0 Cable Modem

Selling my old Motorola SB6121 cable modem. It's the black version and supports DOCSIS 3.0. I used it for a while and it worked fine with my provider, just upgraded recently so I don't need it anymore. It's pretty reliable and easy to set up if you're looking to stop paying those monthly rental fees to the cable company. Has some normal wear from sitting on a shelf but nothing major.
