Overview
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
Address Translation (NAT), Network Address Port Translation (NAPT), and a Stateful Packet
Inspection (SPI) firewall. These features allow you to share a single high-speed public Internet
connection and files between devices in the network by attaching multiple wired/wireless
devices to the wireless business gateway.

CBIG and Guest WiFi Services
Cox Business Internet Gateway and Guest WiFi Services
The Cisco 3829AD Gateway delivers two distinct services; Internet Gateway and Guest WiFi.
Customers who purchase both services have two physical gateways deployed in their business
location.
Internet Gateway Service
Internet Gateway service is delivered via a Cisco 3829AD Gateway to provide both wired and
wireless networks. The customer administrator has full access to the gateway to configure up to
16 wireless networks and other available feature sets as described in this administrators guide.
All networks share bandwidth and priority of IP traffic to and from the various networks and are
equal. Customers may choose from any Cox Business Internet Access speed tiers available in
their market.
Guest WiFi Service
A second gateway, second HFC drop, and a guest WiFi option provide dedicated bandwidth to
customers so that their business’s internet access is not impacted by WiFi users.
This type of configuration ensures that Guest WiFi traffic, such as Netflix or gaming in the
waiting room/lobby, does not impact the core business internet needs. The Guest WiFi gateway
may also be useful when the geographic location of the Internet gateway and intended Guest
WiFi area are far enough apart that a single WiFi access point can’t cover both locations.
The customer has three speed tier options to accommodate anticipated peak simultaneous
users on the dedicated the Guest WiFi network. The options include:

Basic Guest WiFi (5Mbps x 1)

Plus Guest WiFi (15 x 3)

Premium Guest WiFi (28 x 4)
Customers must purchase CBI (Cox Business Internet) to add the Guest WiFi service. Guest
WiFi is delivered via a second cable modem/gateway. The Guest WiFi gateway can have one
(1) SSID per radio enabled. Many of the other Internet gateway features are removed from the
admin interface because this device is dedicated to Guest WiFi users only, and advanced
features are rarely needed.
The Guest WiFi is unmanaged by Cox. This means the device WiFi Capabilities are not actively
monitored for uptime or security events by Cox. Cox does not provide support or configuration
for WiFi end points (PC, MAC, Android, iOS, etc.) The customer admin determines if the WiFi
network is password-protected or open.
Cox is not responsible for customer impacting network or security issues.

Login Instructions
Log in to the Gateway{ XE "Logging in to the Gateway" \t "See" }
This section provides instructions for logging in to the Wireless Business Gateway so that you
can customize the gateway to suit your needs rather than using the default (factory) settings.
Note: It is strongly recommended that you use an Ethernet connection versus Wi-Fi
when you first connect to the gateway. If you use Wi-Fi during initial configuration and
you alter the Service Set Identifier (SSID), you will be dropped from the network when
the change is submitted. You will then have to reconnect using the new SSID.
The same recommendation applies to changing the wireless passphrase. It is best to
make these changes over an Ethernet hard-wired connection..
The gateway uses a default IP address of 192.168.0.1. If you have connected to the gateway
correctly and configured your computer properly, use the following procedures to log in to the
gateway as an administrator.
Figure 1.

Configure Guest Network Settings
The Guest Networks tab is only available in the Cox Business “Internet Gateway” subscription
and gateway configuration. This feature is different from the Cox Business Guest Wi-Fi service
offering because it allows you to define guest Wi-Fi SSIDs for each radio, even though the
Internet service bandwidth tier is shared between all enabled guest Wi-Fi SSIDs. The Guest
Network tab allows you to configure up to seven (7) additional SSIDs per radio. Remember that
these SSIDs share the same Internet bandwidth.
When you subscribe to the Cox Business Guest Wi-Fi service, bandwidth and a second physical
gateway is dedicated for guest Wi-Fi users and there is no contingency to the primary gateway’s
bandwidth. The second gateway dedicated to “Guest WiFi” network will not have access to the
Guest Network tab in the GUI.
The “Guest Network” section allows you to set up the Wi-Fi Radio Guest Network for both Radio
1 and Radio 2, which includes naming the network and designating whether you want to enable
it as a SSID Broadcast. In the Guest Network Settings section, you provide technical
specifications for the DHCP server. When creating additional SSIDs in the “Guest Network” tab,
all networks on the gateway share the Internet access bandwidth. There is no priority given to
any SSID.

Network Name (SSID) The name that you want to assign to the
Service Set Identifier (SSID).
MAC Address (BSSID). Similar to the SSID, the Basic Service
Set Identifier (BSSID) is the 'name' of the wireless network that
shows up under network connections.
SSID Broadcast. An SSID is the name of a wireless local area
network (WLAN). All wireless devices on a WLAN must use the
same SSID in order to communicate with each other.
The SSID on wireless clients can be set manually, by entering
the SSID into the client network settings or automatically, by
leaving the SSID unspecified or blank. A network administrator
often uses a public SSID that is set on the access point and
broadcast to all wireless devices in range. Some wireless
access points disable the automatic SSID broadcast feature to
improve network security.
By disabling the broadcasting of the SSID, or even the beacon
signal itself, you can hide the presence of your wireless network
or at least obscure the SSID itself which is critical for a device to
connect to your network.
Enable. Check this box to allow the SSID broadcast.

Network Name (SSID). The name of the network that you want
to configure
Security Mode. Select the level of security that you want to
apply to the network that you selected from the Network Name
(SSID) drop-down list.
Wired Equivalent Privacy (WEP) is a security protocol for
wireless networks that encrypts transmitted data. Without any
security your data can be intercepted without difficulty. Note:
WEP is a well known compromised security and should not be
used.
WEP has three settings: Off (no security), 64-bit (weak security),
128-bit (a bit better security). WEP is not difficult to crack, and
using it reduces performance slightly.
If you run a network with only the default security, where WEP is
turned off, others can immediately log on to your network and
use your Internet connection.
Wi-Fi Protected Access (WPA) replaces WEP with a protocol
that is — given current technology — impossible to crack.
DHCP Server. Dynamic Host Configuration Protocol (DHCP) is
a networking protocol that is used by servers on an IP network
to allocate IP addresses to computers. The purpose of DHCP is
to automate the IP address configuration of a computer without
a network administrator.
IP Address. An IP address is assigned to a computer for a set
interval, after which, the computer must renew the IP address or
acquire a new one. In this field, enter the IP address of the
DHCP server.
Subnet Mask. A mask is used to determine what subnet an IP
address belongs to. An IP address has two components, the
network address and the host address. For example, the first
two numbers (150.215) in the IP address 150.215.017.009
represent the network address, and the second two numbers
(017.009) identify a particular host on this network.
Subnetting enables the network administrator to further divide
the host part of the address into two or more subnets.
Lease Pool Start. The first IP address in the scope of
addresses that you will use for the DHCP server. After a DHCP
scope is established changes in the number of nodes that
require DHCP leases may change over time.
Lease Pool End. The last IP address in the pool of addresses
that you use for the DHCP server. a certain address pool and
determine that the address pool range needs to be increased,
you can simply delete the scope and recreate it. Deletion of the
scope will.
Lease Time. The amount of time that the scope of leased IP
addresses are valid until they expire. The value can be hours,
days, weeks, months, etc.

Port Range Forwarding Settings allow you to configure ports that are to be used for public
services on your network, such as security cameras, web servers, FTP servers, email servers or
other specialized Internet applications.
Important:
Figure 23.

The gateway normally implements a feature called Port Translation. Port
Translation monitors those ports that are used by your PCs or other devices on
your LAN. This monitoring provides an added level of security beyond what the
firewall provides. However, there are some applications that require the gateway
to use specific ports to connect over the Internet.

Port Range Forwarding continually exposes the selected ports to the public
Internet. This means that the firewall is not active on these ports. The device with
the forwarding IP address can be exposed to hacker attacks while the port range
is being forwarded.

Advanced Gateway Configurations
Advanced Gateway Configurations
The Cisco 3829AD gateway is capable of supporting VLANs (Virtual Local Area Networks)
configured to any of the 4 wired interfaces or wireless SSIDs. The gateway is also capable of
supporting bridged mode for the entire gateway or individual wired interfaces (referred to as
Mixed Mode). The VLAN, Bridge Mode and Mixed Modes can only be enabled by Cox
Communications; these are not advised for majority of business use cases where these
configurations are needed will be extremely rare. If you required these configurations please
contact Cox Business customer care. Cox can remotely enable these capabilities however it is
the responsibility of the customer administrator to configure and manage the settings to meet
their business needs. Cox will only enable the features.
Virtual Local Area Network
The Virtual Local Area Network (VLAN) feature set is used to logically group LAN side network
interfaces to create a VLAN. Each VLAN creates a network broadcast domain and provides
traffic isolation between other VLANs configured.
Customers have requested this type of LAN side port isolation for additional security
(Ethernet/Wi-Fi) as well as the ability to forward or route traffic from specific ports back to Layer
3 routers and switches on the network side.
Note: In the current architecture, VLAN tags cannot be added or stripped for packets
traversing the Wi-Fi interfaces due to performance concerns. However, if the Wi-Ficonnected CPE adds a VLAN tag, it can be prioritized into an upstream service flow. The
current software implementation does not support VLAN double tagging (Q-in-Q
tagging).
The current VLAN implementation only supports IPv4 subnets and addresses. The VLANs are
interface-based. Each interface on the router can be assigned a unique VLAN ID—or multiple
interfaces can be grouped and assigned to the same VLAN ID. However, a specific interface
cannot be a member of more than one VLAN.
VLAN IDs in the range of 2 to 1005 are possible. By default, all interfaces are a member of the
default VLAN ID = 1. Firewall and UpNP are configurable per VLAN via the GUI settings.

User Provisioning Details for VLAN Feature
When the VLAN feature is remotely enabled by Cox Customer Care team, the Web GUI control
page (called VLAN) is available for the advanced user under the Setup tab.
The user can create a VLAN and select the interface they wish to be part of that VLAN. Each
VLAN has its own IP subnet, along with the Firewall and UPnP controls.

Advanced Gateway Configurations
Bridge Mode
The Bridge Mode—which operates at the Data Link Layer (level 2) and does not understand
communications protocol other than the physical medium (MAC), typically an Ethernet—allows
the gateway to run in that mode instead of a router mode.
NAT will be disabled and the gateway will operate exactly as a traditional DOCSIS 3.0. The WiFi capability will be disabled. The Cox Business Customer Care team is the only entity that can
enable this mode.
Note: Customers will rarely prefer this configuration

Advanced Gateway Configurations
Mixed Mode
Each of the 4 Gigabit Ethernet ports available is primarily used in conjunction with Radio 1’s
primary SSID. In case of router or bridge modes, all of these ports will be set to modes with
independent control over ports.
This feature provides the customer with the flexibility to control and configure individual Gigabit
Ethernet ports in either the Bridge or Router mode independently. For example, a customer can
have port 1 and port 2 in Bridge Mode while port 3 and port 4 is in Router Mode.
This is an extremely advanced configuration that the majority of customers will not require. If
you believe Mixed Mode is necessary, or you have technical questions, contact the Cox
Business Technical Support team at 1-877-935-7038.
Note: In case of a Mixed Mode setting, the primary Wi-Fi interface can only be in Router
Mode.
