Cisco 3829AD Gateway Overview
The Cox Business Internet Gateway and Guest WiFi service is based on the Cisco Wireless
Gateway Model DPC3829AD. It is a high-performance gateway that combines a cable modem,
router, and wireless access point(s) in a single device that provides a cost-effective networking
solution for small to medium businesses.
The gateway incorporates (8) bonded downstream channels along with four (4) bonded
upstream channels. These bonded channels can deliver downstream data rates in excess of
400 Mbps and upstream data rates in excess of 120 Mbps. It provides up to eight (8) times
faster download speeds than conventional single-channel DOCSIS
®
2.0 cable modems.
 The gateway supports up to 50 simultaneous users for the 2.4 GHz and another 50
simultaneous users for the 5.0 GHz radio for a total of 100 simultaneous users if both
radios are fully utilized. WiFi distance recommendations - 10,000 square feet for the 2.4
GHz radio and 7,500 square feet for the 5.0 GHz radio.
Note: All environments are different and impacted by several real world factors such as
steel walls, microwaves, and other RF interference
The gateway also offers:
 Dual band simultaneous 2.4Ghz and 5.0Ghz radios with 3x3 MIMO high power antennas
that deliver 802.11ac with beamforming technology (up to 50 users per radio)
 4 Gigabit Ethernet ports
 Stateful Packet Inspection firewall technology
 Static IP addressing (IPV4 and IPV6)
 VPN point-to-point and pass-through
The integrated router features a Dynamic Host Configuration Protocol (DHCP) server, Network

connection and files between devices in the network by attaching multiple wired/wireless
devices to the wireless business gateway.
