SMART/RG DOCSIS 3.0 Gateway SR808AC Router

This SMART/RG DOCSIS 3.0 Gateway modem has 4 LAN ports and a USB port. It supports 2.4 GHz and 5 GHz WiFi. Includes power adapter. Power adapter and cable have a few white paint stains on them. Bought it used on Kijiji a few years ago for a friend with Internet problems, but it turned out to be the wrong model so we never used it. It's been sitting in my closet ever since. It turns on when plugged in.
