A computer with an operating system that supports TCP/IP networking protocols (for example Windows 95/98/NT/Me/2000/XP, Unix, Mac OS 8.5 or higher). An Ethernet 10Mbps or 10/100 Mbps NIC for each computer to be connected to the four-port switch on your Router. An 802.11b or 802.11g wireless NIC. A cable modem or DSL modem with an Ethernet port (RJ-45 connector). An active Internet access account. A Web browser that supports JavaScript, such as Netscape 4.7 or higher, Internet Explorer 5.0 or higher, or Mozilla 1.2.1 or higher.

Front Panel

The front panel of the Router contains a series of indicator lights (LEDs) that help describe the status of various networking and connection operations.
Figure 3 Router - Front Panel
1 Alert LED Orange Indicates a number of different conditions, as described below. Off - The Router is operating normally. Flashing quickly - Indicates one of the following conditions:
The Router has just been started up and is running a self-test routine, or The administrator has invoked the Reset to Factory Defaults command, or The system software is in the process of being upgraded
In each of these cases, wait until the Router has completed the current operation and the alert LED is Off. Flashing slowly - The Router has completed the Reset to Factory Defaults process, and is waiting for you to reset the unit. To do this, remove power, wait 10 seconds and then re-apply power. The Router will then enter the start-up sequence and resume normal operation. On for 2 seconds, and then off - The Router has detected and prevented a hacker from attacking your network from the Internet. Continuously on - A fault has been detected with your Router during the start-up process. Refer to Chapter 6 Troubleshooting. 2 Power LED Green Indicates that the Router is powered on. 3 Wireless LAN (WLAN) Status LED Yellow If the LED is on it indicates that wireless networking is enabled. If the LED is flashing, data is being transmitted or received. If the LED is off, the Wireless LAN has been disabled in the Router, or there is a problem. Refer to Chapter 6 Troubleshooting. 4 Four LAN Status LEDs Green (100 Mbps link) / yellow (10 Mbps link) If the LED is on, the link between the port and the next piece of network equipment is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected, the connected device is switched off, or there is a problem with the connection (refer to Chapter 6 Troubleshooting). The port will automatically adjust to the correct speed and duplex.

LAN Settings

Figure 24 LAN IP Address Screen
This screen displays a suggested LAN IP address and subnet mask of the Router. It also allows you to change the IP address and subnet mask. DHCP The Router contains a Dynamic Host Configuration (DHCP) server that can automatically configure the TCP/IP settings of every computer on your network.
Figure 25 DHCP Server Setup Screen
To activate the DHCP Server option, select Enable the DHCP server with the following settings: and specify the IP pool range. The largest available continuous IP pool will be automatically entered; if this is not appropriate, make your required changes. To disable DHCP, select Do not enable the DHCP server. Click Next when you have finished.

Wireless Settings

Figure 26 Wireless Configuration Screen
This screen displays the Channel and Service Area Name. It also allows you to change these settings. There are a maximum of 14 channels, the number available to you is dependent on the country you reside in. Selecting Clear Channel Select from the Channel drop-down list allows the Router to automatically select an available channel when first powered on. The Service Area Name default for 3Com products is 3Com. Up to 32 (case sensitive) characters can be entered for the Service Area Name. 3Com strongly recommends that you change the SSID to something other than the default. Click Next when you have finished. If you are configuring the Router from a wireless computer any changes you make to the wireless configuration will result in communication between the Router and your computer being lost. This is why 3Com strongly recommends that you configure the Router from a wired computer. It is very important that you set up your wireless clients to use the same Service Area Name or SSID as the one you use on this screen. If your clients use a different Service Area Name then they will not be able to communicate with the Router. The choice of channel is less important as Clients will generally search all of the available channels. You should however make a note of the

channel you select as this may be useful if you experience problems with your clients. Summary
Figure 27 Configuration Summary Screen
When you complete the Setup Wizard, a configuration summary will display. 3Com recommends that you verify the configuration information of the Router and then print this page for your records. Click Finish to display the Wizard completed screen, shown in Figure 28
Figure 28 Wizard Completed Screen
If you have made changes to the LAN Settings or wireless configuration options, you may need to reconfigure the computer you are using in order to make contact with the Router again. Your Router is now configured and ready for use.
See Chapter 5 for a detailed description of the Router configuration screens.

Option Tabs

Each corresponding menu page may also provide sub-sections which are accessed through the use of tabs (see Figure 29 for example). To access a sub-section, simply click on the required tab. Getting Help On every screen, a Help button is available which provides access to the context-sensitive online help system. Click Help for further assistance and guidance relating to the current screen.

WPA Wi-Fi Protected Access (WPA) is a 256 bit encryption method with keys that change over time. WEP Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit encryption method with user configurable fixed keys.
WPA provides a higher level of security, provided by its longer key and dynamic changes made to the key over time. 3Com recommends that you use WPA with any clients which support it. If you enable encryption on the Router, you must reconfigure your wireless PCs to use exactly the same Encryption Type and Keys otherwise the devices will not understand each other. The encryption methods used by the Router secure data transmitted through wireless communications between the Router and its wireless clients. Enabling encryption has no security effect on data transmitted through wired (Ethernet) connections or through your connections to the Internet.
To enable WEP, select WEP from the Security Mode.
Encryption: Choose from 64 bits or 128 bits Passphrase:You can enter a passphrase and click on the Generate button and the router will automatically generate four WEP keys for you. WEP Key1-4:Manaually assign a passphrase for each key. If you selected 64 bits encryption, enter 10 HEX characters (0-F) for each key. If you selected 128 bits encrtpyion,enter 26 HEX characters (0-F) for each key. TX Key:Select a key to be the active key. Click Save to save the setting
To enable WPA, select WPA-PSK or WPA2-PSK from the Security Mode.
Encryption Methods: Select either TKIP or AES as the encryption method. Passphrase:Enter a passphrase between 8 to 63 characters long. Key Renewal:Enter the desired key renewal time in seconds. Click Save to save the setting.

WPA with RADIUS

If you are using a RADIUS server in your network for authentication, you may choose WPA or WPA2 from the Security Mode.
Encryption Methods: Select either TKIP or AES as the encryption method. RADIUS Server:Enter the IP Address of your RADIUS server. RADIUS Port: Enter the port number of your RADIUS server. Shared Key:Enter the shared key. Key Renewal:Enter the desired key renewal time in seconds. Click Save to save the setting.

Connection Control

You can restrict certain wireless clients from accessing the router by specifying their MAC address and enabling access restrictn.

Select Enabled from the drop-down menu and choose whether the specified wireless clients will be prevented or permitted to access the wireless network. Enter their MAC address in the fields below and click Save to save the setting.

Client List

Client List Screen
The Wireless Client List provides details on the devices that are connected to the Wireless LAN. The list is only created when Wireless Networking is enabled. For each device that is connected to the Wireless Lan, the MAC address and Connection Speed of that device is displayed. As you connect more devices to the Wireless LAN, the client list will grow to a maximum of 32 (the maximum number of wireless devices that the Router can support).
Advanced Wireless Settings
Advanced Wireless Settings Screen
You can configure various advanced wireless settings on this screen. Click Save to save the setting.

Internet Settings

Before you can configure the Router, you need to know the IP information allocation method used by your ISP. There are four different ways that ISP scan allocate IP information, as described below: 1 Static IP Address (DSL or Cable) The ISP provides the IP addressing information for you to enter manually. To configure the Router you will need to know the following:
IP Address Subnet Mask ISP Router DNS address(es) Dynamic IP Address (DSL or Cable)
Dynamic IP addressing (or DHCP) automatically assigns the Router IP information. This method is popular with Cable providers. This method is also used if your modem has a built in DHCP server. 3 PPPoE (DSL only) If the installation instructions that accompany your modern ask you to install a PPPoE client on your PC, then select this option. To configure the
Router you will need to know the following:
User name Password Service Name(ifrequired by your ISP)
When you install the Router, you will not need to use the PPPoE software on your PC.
PPTP (DSL or Cable) PPTP is only used by some European providers. If the installation instructions that accompany your modern ask you to setup a dialup connection using a PPTP VPN tunnel then select this option. To configure the Router you will need to know the following:

Use the Routers original Internet MAC address - This field is selected by default and is automatically filled in with the MAC address of the Router.
Use this PCs MAC address - This field is automatically filled in with the MAC address of the PC you are using to configure the Router. You should use this address only if you were previously using this computer to connect directly to your modem. Enter a new MAC address manually - Use this option if you want to specify a new MAC address. Enter the new MAC address.
4 Check all settings and click Save. PPP over Ethernet PPPoE Setup Screen
To setup the Router for use with a PPP over Ethernet connection, use the following procedure: 1 Select PPP over Ethernet in the IP Allocation Mode field. 2 Enter the Host Name (optional). Some ISPs require a host name. If your ISP has this requirement, enter the host name in the Host Name text box.
3 Enter your PPP over Ethernet user name in the PPPoE User Name text box. 4 Enter a password in the PPPoE Password text box. 5 Enter your PPP over Ethernet service name in the PPPoE Service Name text box. Not all ISPs require a PPPoE service name. Only enter a service name if your ISP requires this. 6 Enter the MTU value supplied by your ISP. If you do not know this, leave it at the default value. The default is 1454. 7 Select an idle time from the Maximum Idle Time drop-down list. This value will correspond to the amount of idle time (no Internet activity) that will pass before the Router automatically ends your PPP over Ethernet session. Since the Router contains its own PPPoE client, you no longer need to run PPPoE client software on your computer to access the Internet. PPTP PPTP Setup Screen
To setup the Router for use with a PPTP connection, use the following procedure: 1 Select PPTP (used by some European providers) in the IP Allocation Mode field. 2 Enter your PPTP server address in the PPTP Server Address text box (this is typically the address of your modem). 3 Enter your PPTP user name in the PPTP User Name text box. 4 Enter your password in the PPTP Password text box. 5 Enter the MTU value supplied by your ISP. If you do not know this, leave it at the default value. The default is 1460. 6 Select an idle time from the Maximum Idle Time drop-down list. This value will correspond to the amount of idle time (no Internet activity) that will pass before the Router automatically ends your PPTP session. 7 IP settings must be used when establishing a PPTP connection. To obtain an IP address
Fill in the Initial IP Address, Initial Subnet Mask fields if your ISP has provided you with these settings.

Enabling Remote Administration It is possible to administer the Router remotely. Select one of the following options for remote administration:
Disable Remote Administration - This option is set as default. Enable administration from a single Internet Host - Only the specified Host IP Address can manage the Router. Any other users will be rejected. Enable administration from a whole subnet - This option allows a number of users within the specified Host Network Address and Subnet Mask to administer the Router. Enable administration from any Internet Host - This option allows any host to access the administration pages.
To remotely administer your Router, enter http://xxx.xxx.xxx.xxx:8000 in the location bar of the browser running on the remote computer, where xxx.xxx.xxx.xxx is the Internet IP address of the Router. You may then login using the administration password. Your Internet IP address can be found at the bottom of the screen. Syslog Select Syslog to display the syslog screen.
Check on the check box to enable this feature, and then click Save.

Status and Logs

Selecting Status and Logs from the main menu displays the Status, Logs and Routing Table in yur Web browser window. The Status screen displays a tabular representation of your network and Internet connection. Status Screen

Click the Save Log button to save this information to a file on your PC's hard drive. Click the Refresh button to update the log. Click the Clearn button to clear all the information that is displayed.

Routing Table

Select the Routing table tab to display routing information used by the Router. The information is displayed in the form at shown as below.

http://192.168.1.1

and run the configuration wizard. You may need to restart your computer before you attempt this. 7 When the configuration wizard has completed, you may reconnect your network as it was before.

Wireless Networking

Ensure that you have an 802.11b or 802.11g wireless adapter for each wireless computer, and that it is correctly installed and configured. Verify that each Wireless computer has either Windows 95 or higher or MAC OS 8.5 or higher. Verify that your wireless computers are configured to work in Infrastructure mode and not Ad Hoc mode. The Router contains an Access Point that is designed to operate in Infrastructure mode. Ad Hoc mode is not supported by the Router.
If you have a wired and a wireless NIC in the same computer, ensure that the wired NIC is disabled. Check the status of the Router Wireless LED, it should be lit if wireless is enabled and will flash when there is wireless activity. If not lit go to Wireless Settings and enable wireless networking. Ensure that the TCP/IP settings for all devices are correct. Ensure that the Wireless Clients are using the same SSID or Service Area Name as the Router. The SSID is case-sensitive Ensure that the encryption method and level that you use on your clients are the same as those configured on the Router. The Router can simultaneously support WPA and WEP encryption, but can only support one configuration of each. Ensure that you have the Wireless computer enabled in the list of allowed MAC addresses if you are using Wireless Connection control on the Router. If you are having difficulty connecting or are operating at a low speed try changing the antenna positions on the rear of the Router. For more effective coverage you can try reorientating your antennae. Place one antenna vertically and one horizontally to improve coverage. Additionally consider moving the wireless computer closer to the Router to confirm that the building structure or fittings are not adversely affecting the connectivity. If this resolves the problem consider relocating the Wireless computer or the Router, or trying a different channel on the Router. Sources of interference: The 2.4Ghz ISM band is used for 802.11b and 802.11g. This is generally a licence free band for low power applications, and you may have other devices at your location that operate in this frequency band. You should take care to ensure that there are no devices like microwave ovens for example close to the Router or wireless computers as this could affect receiver sensitivity and reduce the performance of your network. If you are unsure try relocating both the wireless computers and the Router to establish whether this problem exists. Most wireless computer Adapters will scan the channels for the wireless Router. If a wireless computer has not located the Router then try initiating a search manually if the client software supports this feature or manually set the channel on your wireless computer to correspond to the Router channel number. Please refer to your Wireless computer adapter documentation and vendor to do this.

Type Two In larger networks, where there are more devices, the IP address of 192.168.100.8 is, again, split into two parts but is structured differently:
Part one (192.168) identifies the network on which the device resides. Part two (.100.8) identifies the device within the network.
How does a Device Obtain an IP Address and Subnet Mask?
This type of IP Address operates on a subnet mask of 255.255.0.0. See an example about how a network (only four computers represented) and a Router might be configured. IP Addressing and Subnet Masking
Device PC 1 PC 2 PC 3 PC 4 Router IP Address 192.168.100.8 192.168.201.30 192.168.113.155 192.168.002.230 192.168.002.72 Subnet Mask 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0
There are three different ways to obtain an IP address and the subnet mask. These are:
Dynamic Host Configuration Protocol (DHCP) Addressing Static Addressing Automatic Addressing (Auto-IP Addressing)

DHCP Addressing

The Router contains a DHCP server, which allows computers on your network to obtain an IP address and subnet mask automatically. DHCP assigns a temporary IP address and subnet mask which gets reallocated once you disconnect from the network. DHCP will work on any client Operating System such as Windows 95, Windows 98 or Windows NT 4.0. Also, using DHCP means that the same IP address and subnet mask will never be duplicated for devices on the network. DHCP is particularly useful for networks with large numbers of users on them.

Static Addressing

You must enter an IP Address and the subnet mask manually on every device. Using a static IP and subnet mask means the address is permanently fixed. Network devices use automatic IP addressing if they are configured to acquire an address using DHCP but are unable to contact a DHCP server.

Auto-IP Addressing

Automatic IP addressing is a scheme where devices allocate themselves an IP address at random from the industry standard subnet of 169.254.x.x (with a subnet mask of 255.255.0.0). If two devices allocate themselves the same address, the conflict is detected and one of the devices allocates itself a new address. Automatic IP addressing support was introduced by Microsoft in the Windows 98 operating system and is also supported in Windows 2000.
