Getting Started

Inside the Box

Before you install the CH7486E Wireless Gateway, verify that the following items

are included in the box with the CH7486E:

Item

Description

Power Adapter

Connect the CH7486E to an AC electrical

outlet

WiFi Sticker Card

For user placing the WiFI SSID/Password

information for 2.4GHz and 5GHz for future

use.

Ethernet Cable

Connect the CH7486E to PC or Notebook

You must have the latest service packs and patches installed on your computer for

your operating system.

You will need a 75-ohm coaxial cable with F-type connectors to connect the

CH7486E to the nearest cable outlet. If a TV is connected to the cable outlet, you

may need a 5 to 900 MHz RF splitter and two additional coaxial cables to use the

TV and the CH7486E.

Before You Begin

Take the following precautions before installing the CH7486E:



Postpone installation until there is no risk of thunderstorm or lightning activity in

the area.



To avoid potential shock, always unplug the power cord from the wall outlet

or other power source before disconnecting it from the CH7486E rear panel.



To prevent overheating the CH7486E, do not block the ventilation holes on

the sides of the unit. Do not open the unit. Refer all service to your Internet

Service provider.

Check that you have the required cables, adapters, and adapter software. Verify

that the proper drivers are installed for the Ethernet adapter on each networked

computer. For information on WLAN setup, see

Position Your Wireless Router

The CBN CG7486E Wireless Gateway lets you access your network from anywhere

within the operating range of your wireless network. However, the operating distance

or range of your wireless connection can vary significantly depending on the physical

placement of your Gateway. For example, the thickness and number of walls the

wireless signal passes through can limit the range. For best results, place your router:



First and foremost, don't settle prematurely on a location for the wireless

access point or router. Experiment; try placing the device in several different

promising locations. While trial-and-error may not be the most scientific way to

find a good spot for your equipment, it is often the only practical way to

assure the best possible Wi-Fi performance.



Strive to install the wireless access point or router in a central location. If you

have only one wireless client, installing the base station near this client is best.

For WLANs with multiple wireless clients, find a good compromise position.

Clients too far away from the base station will manage only 10% - 50%

the bandwidth of clients nearby to it. You might need to sacrifice the network

performance of one client for the good of the others.

13



Next, avoid physical obstructions whenever possible. Any barriers along the

"line of sight" between client and base station will degrade a Wi-Fi radio

signal. Plaster or brick walls tend to have the most negative impact, but really

any obstruction including cabinets or furniture will weaken the signal to some

degree. Obstructions tend to reside closer to floor level; therefore, some folks

prefer to install their wireless access point / router on or near the ceiling.



Avoid reflective surfaces whenever possible. Some Wi-Fi signals literally

bounce off of windows, mirrors, metal file cabinets and stainless steel

countertops, lessening both network range and performance.



Install the wireless access point or router at least 1 m (3 feet) away from other

home appliances that send wireless signals in the same frequency range.

Such appliances include some microwave ovens, cordless telephones, baby

monitors, and home automation equipment like X-10 devices. Any appliance

that transmits in the same general range as802.11b or 802.11g (2.4 GHz) can

generate interference.



Likewise, install the unit away from electrical equipment that also generates

interference. Avoid electric fans, other motors, and flourescent lighting.



Note: To get better wireless coverage, please put your

Connecting the CH7486E

Before starting, be sure the computer is turned on and the CH7486E power cord is

unplugged.

1.

Connect one end of the coaxial cable to the cable outlet or splitter.

2.

Connect the other end of the coaxial cable to the Cable connector on the

CH7486E. Hand-tighten the connectors to avoid damaging them.

3.

Plug the power cord into the Power port on the CH7486E.

4.

Plug the other end of the power cord into an electrical wall outlet.

This automatically powers on the gateway. You do not need to unplug the

gateway when it is not in use. The first time you plug in the CH7486E, allow it 5

to 30 minutes to find and lock on the appropriate communications channels.

5.

Plug the other end of the telephone cord of a single or two-line telephone

into the

TEL 1/2

port on the rear of the CH7486E.

6.

Plug the telephone cord of a single or two-line telephone into the telephone.

7.

Connect the Ethernet cable to the Ethernet port on the computer, and

connect the other end of the Ethernet cable to the Ethernet port on the

gateway.

8.

Check that the LEDs on the front panel cycle through the following sequence:

successfully and ready for Internet access

Setting Up Internet Access

After installing the CH7486E, check that you can connect to the Internet. You can

retrieve an IP address for your computer’s network interface using one of the

following options:



Retrieve the statically defined IP address and DNS address



Automatically retrieve the IP address using the Network DHCP server

The CBN CH7486E Wireless Gateway provides a DHCP server on its LAN. It is

recommended that you configure your LAN to obtain the IPs for the LAN and DNS

server automatically.

Make sure all computers on your LAN are configured for TCP/IP. After configuring

TCP/IP on your computer, you should verify the IP address.

Note

:

For UNIX or Linux systems, follow the instructions in the

applicable user documentation.

Configuring TCP/IP in Windows XP

1.

Open the Control Panel.

2.

Double-click Network Connections to list the Dial-up and LAN or High-Speed

Internet connections.

3.

Right-click the network connection for your network interface.

4.

Select Properties from the drop-down menu to display the Local Area

Connection Properties window. Be sure Internet Protocol (TCP/IP) is checked.

5.

Select Internet Protocol (TCP/IP) and click Properties to display the Internet

Protocol (TCP/IP) Properties window.

6.

Select Obtain an IP address automatically and Obtain DNS server address

automatically.

7.

Click OK to save the TCP/IP settings and exit the TCP/IP Properties window.
