Used (normal wear)
Moto / Arris Surfboard SB-6121 cable modem for Comcast/Xfinity and other cable internet. DOCSIS 3.0 with 4x4 channels, up to 172Mbps.
This was working great when I switched away from cable internet. Includes the modem, power brick and the instruction sheet. E-Z contactless local pickup.
This is just the modem, so you will also need a WiFi router to go with it. NOTE 1 - the Comcrap people will tell you this is “end of life” so they may not activate it unless you already have one. NOTE 2 - There’s only one light in the picture bc I don’t have cable service to connect it to.
