I am selling a used Arris SURFboard SB8200 Docsis 3.1 modem, which is compatible with Xfinity internet (and maybe others). These typically retail for $150 or more. Full specs can be found on the Arris product page, but it has a coax upstream connection, two gigabit ethernet LAN ports, and provides "32 downstream x 8 upstream DOCSIS 3.0 bonded channels" and "2 downstream x 2 upstream OFDM DOCSIS 3.1 channels," whatever that means. It's good for up to 1Gbps internet plans. There are basically no setup or management options other than having the device provisioned by Xfinity (or your compatible ISP of choice). It worked fine for us - I'm selling it because we upgraded our LAN and I wanted a device with a 2.5Gbps LAN port. It can be wall mounted.

Cash only, porch pickup near 24th and Uinta St.
