Obtain WAN IP Address by PPPoE (for most dial-up users) Select the item according to your situation and enter the information required by your ISP. Press Apply to confirm the settings.
7.2.2 DHCP This page allows configuration of DHCP server for LAN. You need to enable (default) DHCP server feature and indicate the Starting Local Address for the DHCP server to start with when issuing IP addresses and the number of CPEs (clients). Starting Local Address Because the CBW500’s default IP address is 192.168.0.1.the Starting Local address must be 192.168.0.2 or greater, but smaller than 192.168.0.253. The default Starting Local Address is 192.168.0.10.
The DHCP Client Lease Info table displays the PCs that are given IP addresses by the CBW500. For each PC, the list shows the MAC Address, IP Address, Subnet Mask, Duration and Expires. 7.3 Advanced 7.3.1 Options This page allows configuration of advanced features of the CBW500. WAN Blocking By enabling the Block WAN feature, you can prevent your network from being pinged or detected by other Internet users. This feature also reinforces your network security by hiding your network ports.
PPTP PassThrough PPTP (Point to Point Tunneling Protocol) is the method used to enable VPN* sessions to a Windows NT4.0, 2000 server. To allow tunnels to pass through the CBW500. The default setting is enable. *VPN (Virtual Private Networking) is a security measure that basically creates a secure connection between two remote locations. Remote Config Management This feature allows you to manage your Gateway from a remote location, via the Internet.

7.5 Parents Control 7.5.1 Basic This page allows basic selection of rules which block certain Internet content and Web sites. When you change your Parental Control settings, you must click on the appropriate “Apply”, “Add” or “Remove” button for your new settings to take effect. Refresh your browser to see the currently active settings.
7.6 Wireless 7.6.1 Basic This page allows configuration of the AP (Access Point) parameters, including the SSID and channel number. Network Name (SSID) SSID (Service Set Identifier) is a unique identifier for your wireless network. You must have the same SSID entered into the CBW500 and each of its wireless clients. The default SSID is CBW500. Network Type Select Open to indicate the network as an open network system and select Closed to indicate the network as a closed network system.
Country/Channel Select your region and proper channel. Channel is a similar concept to any radio device. The CBW500 allows you to choose different radio channels in the wireless spectrum. Regional Channel North American 1-11 Japan 1-14 European (ETSI) 1-13 Spain 10-11 France 10-13 Enter the correct channel in field to correspond with your network settings. All devices in your network must set to the same channel in order to function properly.
7.6.2 Security This page allows configuration of the WEP keys and/or passphrase. CBW500 is equipped with WPA (Wireless Protected Access), the latest security standard. It also supports the legacy security standard, WEP (Wired Equivalent Privacy). You must first determine which standard you want to use and then configure the related settings. Note: To use WPA security, all your clients must be upgraded to drivers and software that support it. A free security patch download is available from Microsoft.
There are two types of WPA security: WPA Pre Shared Key (without server) and WPA (with server). WPA Pre Shared Key uses a so-called pre-shared key as the security key. A pre-shared key is a password. Each client uses the same key to access the network. Typically, this mode will be used in a home environment. WPA (with server) is a configuration when there is a radius server distributes the keys to the clients automatically. This is typically used in a business environment. Network Authentication 802.1x 802.
PassPhrase Passphrase is used much like a password. It simplifies the WEP encryption process by automatically generating the WEP keys for the CBW500. A passphrase is an easy way to generate hexadecimal keys. Enter any word, up to 30 characters, and then click Generate WEP Keys button, or manually typing up to four keys. If your wireless cards support passphrase, you can enter the same passphrase on all the wireless cards. Or you may also manually enter the key elements into the setting table.
7.6.3 Access Control This page allows configuration of the Access Control to the AP as well as status on the connected clients. Access Control allows you to control which wireless-equipped PCs may communicate with the CBW500 according to their MAC addresses. The number is up to a maximum of 80 MAC addresses. Select the MAC Restrict Mode (Allow or Deny) and indicate the MAC address in the field and then click Apply.
7.6.4 Advanced This page allows configuration of data rates and Wi-Fi thresholds. 54gTM Mode 54g Auto In this mode, the CBW500 is compatible with 802.11b and 54g wireless clients simultaneously. This is the factory default mode and ensures successful operation with all Wi-Fi-compatible devices. If you have a mix of 802.11b and 54g clients in your network, we recommend you set the CBW500 to 54g-Auto mode. This setting should only be changed if you have a specific reason to do so.
54g LRS It is recommended that DO NOT use this mode unless you have a very specific reason to do so. 54g LRS (Limited Rate Support) mode exists only to solve unique problems that may occur with some 802.11b client adapters and is NOT necessary for interoperability of 54g and 802.11b standards. Note: In some cases, older 802.11b clients may not be compatible with 54g wireless. These adapters tend to be of inferior design and may use older drivers or technology.
Beacon Interval The default beacon interval is 100 milliseconds. A beacon is a short frame that is sent from the AP (Access Point) to stations in order to organize and synchronize wireless communication on the WLAN (Wireless LAN). A beacon includes the wireless LAN service area, the AP address, the broadcast destination addresses, a time stamp and DTIM (Delivery Traffic Indication Message). Enter a value between 1 and 65,535 (milliseconds). This value indicates the frequency interval of the beacon.
Troubleshooting Basic Connection Check that the CBW500 is connected to your computers and the Cable modem as well as all the equipment is powered on. Check that the LAN and WAN port link status LEDs are lighted, and that any corresponding LEDs and the network adapter are also lighted. Ensure that the computer have completed their start-up procedure and are ready for use. Some network interfaces may not be correctly initialized until the start-up procedure has completed.
Connecting to the Internet Confirm that the physical connection between the Cable modem and CBW500 is OK, and the link status LEDs on both CBW500 and Modem are lighted. Confirm that the connection between the Cable modem and its interface is OK. Ensure that you have entered the correct information into the CBW500 configuration screen as required by your ISP. Forgotten Password You need to reset the CBW500 to its factory default settings if you do not know or have forgotten the logging password.
If you are having problem connecting or are operating at a low speed try to change the antenna positions of the CBW500. For more effective coverage you can try to re-orientate your antenna. Place one antenna vertically and the other horizontally to improve the coverage. In addition, moving the wireless computer closer to the CBW500 to confirm that the building structure or fittings are not adversely affecting the connectivity.
