IntroductionIntroduction
This Chapter provides an overview of the CNWR-811P's features and capabilities.
Congratulations on the purchase of your new CNWR-811P Multi-Function Wireless A/P
Router. The CNWR-811P is a multi-function device providing the following services:
• Shared Internet access via an ADSL or Cable modem.
• Wireless LAN Access Point (base station) for equipment compliant with the IEEE802.11b
(DSSS) specifications.
• Network Printer – LAN users can share the printer attached to the CNWR-811P

The CNWR-811P Multi-Function Wireless A/P Router can also be used to connect your local
LAN to a remote LAN or WAN, instead of providing shared Internet Access.
CNWR-811P Features
The CNWR-811P incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use.
LAN Features
•
Dual LAN ports.
Normally, the “Hub” port is used to connect the CNWR-811P to your LAN. But if desired,
the “PC” port can be used to connect the CNWR-811P directly to your PC, using a standard LAN cable.

via the CNWR-811P's built-in static routing table. If NAT (Network Address Translation)
is disabled, the CNWR-811P will function as a static router.

NAT Firewall Protection
The firewall protection provided by the CNWR-811P is an intrinsic side
effect of NAT (Network Address Translation). All users on the LAN share a
single external IP address. From the external viewpoint, there is no network,
only a single device.
For internal users, the CNWR-811P acts as a “transparent proxy server”,
translating the multiple internal IP addresses into a single external IP address.
For external requests, any attempt to connect to local resources are blocked.
The CNWR-811P will not “reverse translate” from a global IP address to a
local IP address.
This type of “natural” firewall provides an impregnable barrier against
malicious attacks.

CNWR-811P User Guide
Configuration Program
The CNWR-811P contains a HTTP server. This enables you to connect to it, and configure it,
using your Web Browser.
Most Browsers should work, provided they support HTML tables and forms.
Preparation
Before attempting to configure the CNWR-811P, please ensure that:
• Your PC can establish a physical connection to the CNWR-811P. The PC and the CNWR-
811P must be directly connected (using the “PC” port on the CNWR-811P) or on the same
LAN segment.
• The CNWR-811P must be installed and powered ON.
• If the CNWR-811P's default IP Address (192.168.0.1) is already used by another device,
the other device must be turned OFF until the CNWR-811P is allocated a new IP Address
during configuration.
Connecting to the CNWR-811P
To establish a connection from your PC to the device:
1. After installing the CNWR-811P in your LAN, start your PC. If your PC is already run-
ning, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the CNWR-811P, as in the
following example, which uses the CNWR-811P’s default IP Address:
HTTP://192.168.0.1
4. You should then see the LAN screen.
If you can't connect
If the CNWR-811P does not respond, check the following:
• The CNWR-811P is properly installed, LAN connection is OK, and it is powered
ON.
• Ensure that your PC and the CNWR-811P are on the same network segment. (If
you don't have a router, this must be the case.)
• If your PC is using a fixed IP Address, its IP Address must be within the range
192.168.0.2 to 192.168.0.254 to be compatible with the CNWR-811P's default
IP Address of 192.168.0.1. Also, the Network Mask must be set to
255.255.255.0. See Chapter 4 – PC Configuration for details on checking your
PC’s TCP/IP settings.

Configuration
Password
If you have assigned a password to the CNWR-811P you will be prompted for the password, as
shown below.
Figure 5: Password Dialog
• Leave the "User Name" blank.
• Enter the password for this device, if one has been set.
If no password has been set, this dialog will not appear.
Navigation & Data Input
• Use the menu bar on the left of the screen, and the "Back" button on your Browser, for
navigation.
• Changing to another screen without clicking "Save" does NOT save any changes you may
have made. You must “Save” before changing screens or your data will be ignored.
On each screen, clicking this icon will display
help for that screen.

unless the address is already in use or your LAN is using a different IP
address range. In the latter case, enter an unused IP Address from within
the range used by your LAN.
The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Network Mask for the LAN segment
to which the CNWR-811P is attached. i.e. the same value as the PCs on
that LAN segment.
If Enabled, the CNWR-811P will allocate IP Addresses to PCs on your
LAN. The default and recommended value is Enabled.

Select the value you wish to use on your Wireless LAN. If you experience lost connections and/or slow data transfers you may need to
experiment with different channels to see which is the best.
If OFF (default), data is NOT encrypted before being transmitted.
• If selected, data is encrypted, using the default key, before being
transmitted. The receiving station must be set to 64 Bit Encryption,
and have the same Key value in the same position in its key table.
Otherwise, it will not be able to decrypt the data.
Default Key
•
Select the key you wish to be the default. Transmitted data is
ALWAYS encrypted using the Default Key; the other Keys are for
decryption only.
Key Table
•
• This table is used when Encrypting and Decrypting data. All
stations, including this Access Point, always transmit data encrypted using their default key. The key number (1, 2, 3, 4) is
also transmitted. The receiving station will use the key number
(1, 2, 3, 4) to determine which key value to use for decryption.
If the key value does not match the transmitting station, decryption will fail.
• The easiest way to ensure there are no problems is to have every
Station, including the Access Point, use the same key table (all
entries identical). Then, it does not matter which key is used as
the default key.
• If selected, data is encrypted using the key before being transmitted.
The receiving station must be set to use 128 Bit Encryption, and
have the same Key value. Otherwise, it will not be able to decrypt
the data.
