Motorola SURFboard SB6121 Cable Modem

This is a used but excellent condition Motorola SURFboard SB6121 Cable Modem. Designed with DOCSIS 3.0 technology and 4-channel downstream/4-channel upstream bonding, it’s well-suited for standard broadband internet connections (historically up to ~100-200 Mbps). The unit features a compact design, easy plug-in setup via coaxial cable + Ethernet output, and comes tested and working. While this model may not be compatible with the very highest speed tiers on some providers, it remains a reliable modem for moderate internet plans, backup usage, or secondary location setups. Fits well in a home or rental-unit environment, and is in “used-excellent” condition (minimal wear, clean finish, fully functional indicators & ports).
