Overview
The CBN CH7486E Wireless Gateway is the worldwide most compact EuroDOCSIS
3.0 Voice Gateway with stylish and elegant outlook, designed for your home,
home office, or small business/enterprise. It can be used in households with one or
more computers capable of wireless connectivity for remote access to the
wireless gateway.
This user guide provides product overview and setup information for the CH7486E.
It also provides instructions for installing the wireless gateway and configuring the
wireless LAN, Ethernet, router, DHCP, and security settings.
Contact Information
For any questions or assistance with the CH7486E Wireless Gateway, contact
your Internet Service provider.
Standard Features
The CH7486E Wireless Gateway combines high-speed Internet access,
networking, and computer security for a home or small-office LAN. It offers the
following features:
Combination of five separate products in one compact unit —an EURO
DOCSIS® 3.0 cable modem, IEEE 802.11b/g/n/ac wireless access point,
Ethernet 10/100/1000 Base-T connections, VoIP Internet telephone
connections, and firewall.
An integrated high-speed cable modem for continuous broadband access
to the Internet and other online services with much faster data transfer than
traditional dial-up or ISDN modems.
Advanced firewall for enhanced network security from undesired attacks
over the Internet. It supports stateful-inspection, intrusion detection, DMZ,
denial-of-service attack prevention, and Network Address Translation (NAT).
One broadband connection for up to 253 computers to surf the web; all
computers on the LAN communicate as if they were connected to the same
physical network.
Two 10/100/1000Base-T Ethernet uplink ports supporting half- or full-duplex
connections with auto-MDIX capability.

5
An IEEE 802.11n/ac wireless access point to enable laptop users to remain
connected while moving around the home or small office or to connect
desktop computers without installing network wiring. Depending on distance,
wireless connection speeds can vary.
CH7486E wireless function supports Wi-Fi 2.4G/5G dual-band mode.
A secure Wireless Fidelity (Wi-Fi) broadband connection for Wi-Fi enabled
devices on your network, such as your mobile, laptops, tablet, printers, PDAs,
and desktops.
Routing for a wireless LAN (WLAN) or a wired Ethernet LAN; you can connect
more than two computers using hubs and/or switches
A built-in DHCP server to easily configure a combined wired and/or wireless
Class C private LAN.
Virtual private network (VPN) pass-through operation supporting IPSec, PPTP,
or L2TP to securely connect remote computers over the Internet.
CH7486E Configuration Manager (CMGR) which provides a graphical user
interface (GUI) for easy configuration of necessary wireless, Ethernet, router,
DHCP, and security settings.
CH7486E LAN Choices
You can connect up to 253 client computers to the CH7486E using one or any
combination of the following network connections:
Wi-Fi wireless LAN (WLAN)
Ethernet local area network (LAN)
Wireless LAN
Wireless communication occurs over radio waves rather than a wire. Like a
cordless telephone, a WLAN uses radio signals instead of wires to exchange data.
A wireless network eliminates the need for expensive and intrusive wiring to
connect computers throughout the home or office. Mobile users can remain
connected to the network even when carrying their laptop to different locations
in the home or office.
Each computer or other device on a WLAN must be Wi-Fi enabled with either a
built-in or external wireless adapter.
Laptops —Use a built-in wireless notebook adapter, a wireless PCMCIA slot
adapter, or a wireless USB adapter.
Desktops —Use a wireless PCI adapter, wireless USB adapter, or compatible
product in the PCI slot or USB port, respectively.

Sample Wireless Network Connections (CH7486E model shown)
Your maximum wireless operation distance depends on the type of materials
through which the signal must pass and the location of your CH7486E and clients
(stations). CBN cannot guarantee wireless operation for all supported distances in
all environments.
Note: To get better wireless coverage, please put your
CH7486E wireless gateway VERTICALLY ONLY
Wired Ethernet LAN
You can easily connect any PC with an Ethernet cable to the CH7486E Ethernet
port. Because the CH7486E Ethernet port supports auto-MDIX, you can use a
straight- through or cross-over cable to connect a hub, switch, or computer. Use
category 5, or better, cabling for all Ethernet connections.

7
Sample Ethernet to Computer Connection (CH7486E model shown)
A wired Ethernet LAN with more than two computers requires one or more hubs,
switches, or routers. You can:
Connect a hub or switch to any Ethernet port on the CH7486E.
Use Ethernet hubs, switches, or routers to connect up to any combination of
253 computers and wireless clients to the CH7486E.
More detailed information on Ethernet cabling is beyond the scope of this
document.

Front Panel
The CH7486E front panel contains indicator lights and the Wi-Fi / WPS button
which is used to configure Wi-Fi Protected Security (WPS) on compatible clients
connected to the CH7486E network.

Activity LED - Green LED defines the activity of the Ethernet
connector.
When LED is ON, this indicates that there is no data traffic and a
connection is stabilized.
When LED is FLASHING, this indicates that there is data being
transmitted upstream or downstream.
When LED is OFF, this indicates that the unit is not powered or there
is no Ethernet connection.
