-A router made by Smart/RG (now a subsidiary of Adtran), it is/was commonly deployed by ISPs at their customer's premises. It is Broadcom-based and offers gigabit ethernet connectivity as well as reasonable wireless performance on the 802.11ac, as well as 802.11a/b/g/n bands using its antennas. It also features two USB ports, including a USB3.0 that can be used for sharing a storage device and act as a makeshift NAS. +A router made by Smart/RG (now a subsidiary of Adtran), it is/was commonly deployed by ISPs at their customer's premises.

 Physically, it appears to be well-ventilated and features three heat sinks on the inside. Features a removable, weighted foot that can either prop the router upright (the default), or affixed to the back and allow for wall mounting. Physically, it appears to be well-ventilated and features three heat sinks on the inside.
