Data Sheet
Cisco Model DPC3941B DOCSIS 3.0 24x4
Wireless Business Gateway
If you’re looking for a cost
-effective, high performance networking gateway for a small
office, you’ve just found it. The Cisco
®
Model DPC3941B DOCSIS 3.0 24x4 Wireless
Business Gateway is multiple solutions in one product. It combines a cable modem, a
router, and 802.11ac wireless access points in a single device. The gateway delivers
a faster connection to the Internet by incorporating 24 bonded downstream channels
along with four bonded upstream channels. The bonded channels can deliver
downstream data rates that exceed 900 Mbps and upstream data rates that exceed
120 Mbps. Downstream rates are up to 24 times faster than conventional
single-channel DOCSIS
®
2.0 cable modem rates.
The Cisco Model DPC3941B Business Gateway (Figure 1) is designed to meet DOCSIS 3.0 specifications and
backward compatibility for operation in DOCSIS 2.0, 1.1, and 1.0 networks.

The integrated router features a Dynamic Host Configuration Protocol (DHCP) server, Network Address
Translation (NAT), Network Address Port Translation (NAPT), and a stateful packet inspection (SPI) firewall. These
features allow the user to share a single high-speed public Internet connection and to share files and folders
between devices in the home network by attaching multiple wired and wireless devices in the active home or office
to the wireless Business gateway.
Consumer-friendly features like Wireless Protected Setup (WPS) and user-configured parental controls can protect
the home network from unwelcome intruders and protect family members from access to undesirable websites.
