Steren COM-820 User manual

Before using your new Wireless Router, please read this
instruction manual to prevent any damage. Put it away in a
safe place for future references.
INTRODUCTION
The Wireless Router integrates 4-port Switch, firewall,
NAT-router and Wireless AP. Its design is dedicated to Small
Office/Home Office (SOHO) wireless network solutions. The
Wireless Router will allow you to connect your network wirelessly
better than ever, sharing Internet Access, files and fun, easily
and securely.
The router provides wireless LAN 64/128/152-bit WEP
encryption security, and WPA/WPA2 and WPA-PSK/WPA2-PSK
authentication, as well as TKIP/AES encryption security. It also
supports VPN pass-through for sensitive data secure
transmission.
Complies with the IEEE 802.11g/b standards and adopts 108M
Super GTM WLAN transmission technology so that the data
transmission rate is up to 108Mbps. It adopts 2x to 3x eXtended
Range WLAN transmission technology so that transmission
distance is 2-3 times of traditional IEEE 802.11g/b solutions.
It is compatible with all IEEE 802.11g and IEEE 802.11b
products.
It also supports Virtual Server and DMZ host for Port Triggering
needs, and remote management and log so that network
administrators can manage and monitor the network on real
time.

CONNECTING THE ROUTER
System Requirements
Broadband Internet Access Service (DSL/Cable/Ethernet)
One DSL/Cable modem that has an RJ45 connector (you do not
need it if you connect the router to Ethernet)
Each PC on the LAN needs a working Ethernet Adapter and an
Ethernet cable with RJ45 connectors
TCP/IP protocol must be installed on each PC
Web browser, such as Microsoft Internet Explorer 5.0 or later,
Netscape Navigator 6.0 or later
INSTALLATION ENVIRONMENT REQUIREMENTS
Not in direct sunlight or near a heater or heating vent
Not cluttered or crowded. There should be at least 2 inches of
clear space on all sides of the router
Well ventilated (especially if it is in a closet)
Operating temperature: 32°~104°F
Operating Humidity: 10%~90%RH, Non-condensing
CONNECTING THE ROUTER
Before you install the router, you should connect your PC to the
Internet through your broadband service successfully. If there is
any problem, please contact your ISP. After that, please install
the router according to the following steps. Don’t forget to pull
out the power plug and keep your hands dry.
ENGLISH
ENGLISH-5

1. Power off your PC(s), Cable/DSL modem, and the router.
2. Locate an optimum location for the router. The best place
is usually near the center of the area in which your PC(s) will
wirelessly connect. The place must accord with the Installation
Environment Requirements.
3. Adjust the direction of the antenna. Normally, upright is a good
direction.
4. Connect the PC(s) and each Switch/Hub on your LAN to the
LAN Ports on the router, shown in figure 1.
5. Connect the DSL/Cable Modem to the WAN port on the router,
shown in figure 1.
6. Connect the AC power adapter to the AC power socket on the
router, and the other end into an electrical outlet. The router will
start to work automatically.
7. Power on your PC(s) and Cable/DSL modem.

QUICK INSTALLATION GUIDE
After connecting the Router into your network, you should
configure it. This chapter describes how to configure the basic
functions of your Wireless Router. These procedures only take
you a few minutes. You can access the Internet via the router
immediately after successfully configured.
TCP/IP CONFIGURATION
The default IP address of the Wireless Router is 192.168.1.1,
and the default Subnet Mask is 255.255.255.0. These values can
be seen from the LAN.
They can be changed as you desire, as an example we use the
default values for description in this guide.
Connect the local PCs to the LAN ports on the router. There are
then two means to configure the IP address for your PCs.
Configure the IP address manually
1) Set up the TCP/IP Protocol for your PC(s). If you need
instructions as to how to do this, please refer to Appendix B:
“Configuring the PCs.”
2) Configure the network parameters. The IP address is
192.168.1.xxx (“xxx” is from 2 to 254), Subnet Mask is
255.255.255.0, and Gateway is 192.168.1.1 (The router’s default
IP address)
Obtain an IP address automatically
1) Set up the TCP/IP Protocol in “Obtain an IP address
automatically” mode on your PC(s). If you need instructions as
to how to do this, please refer to Appendix B: “Configuring the
PCs.”
2) Power off the router and PC(s). Then turn on the router, and
restart the PC(s). The built-in DHCP server will assign IP
addresses for the PC(s).
Now, you can run the Ping command in the command prompt to
verify the network connection between your PC(s) and the router.
The following example is in Windows 2000 OS.
Open a command prompt, and type ping 192.168.1.1, and then
press Enter.

If the result displayed is similar to that shown in figure 2, the
connection between your PC and the router has been
established.
If the result displayed is similar to that shown in figure 3, it
means that your PC has not connected to the router. Please
check it following these steps:
1. Is the connection between your PC and the router correct?
The Link/Act LEDs of LAN port on the router and LEDs on
your PC’s adapter should be lit.

2. Is the TCP/IP configuration for your PC correct?
If the router’s IP address is 192.168.1.1, your PC’s
IP address must be within the range of 192.168.1.2 ~
192.168.1.254, the gateway must be 192.168.1.1
QUICK INSTALLATION GUIDE
With a Web-based (Internet Explorer or Netscape® Navigator)
utility, the Wireless Router is easy to configure and manage. The
Web-based utility can be used on any Windows, Macintosh or
UNIX OS with a web browser.
Connect to the router by typing http://192.168.1.1 in the address
field of web browser.
After a moment, a login window will appear similar to that shown
in Fig. 4. Enter admin for the User Name and Password, both in
lower case letters. Then click the OK button or press the Enter
key.
If the above screen does not prompt, it means that
your web-browser has been set to a proxy. Go to Tools
menu>Internet Options>Connections>LAN Settings,
