INTRODUCING THE ROUTER

Welcome to the world of networking with 3Com. In the modern business environment, communication and sharing information is crucial. Computer networks have proved to be one of the fastest modes of communication but, until recently, only large businesses could afford the networking advantage. The OfficeConnect product range from 3Com has changed all this, bringing networks to the small office. The products that compose the OfficeConnect range give you, the small office user, the same power, flexibility, and protection that has been available only to large corporations. Now, you can network the computers in your office, connect them all to a single Internet outlet, and harness the combined power of all of your computers.
OfficeConnect Wireless 54Mbps/108Mbps 11g cable/DSL Router
The OfficeConnect Wireless 54Mbps/108Mbps 11g cable/DSL Router is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several wired and wireless computers. The Router also provides protection in the form of an electronic firewall, preventing anyone outside of your network from seeing your files or damaging your computers. The Router can also prevent your users from accessing Web sites which you find unsuitable. Figure 1 shows an example network without a Router. In this network, only one computer is connected to the Internet. This computer must always be powered on for the other computers on the network to access the Internet.
CHAPTER 1: INTRODUCING THE ROUTER
Figure 1 Example Network Without a Router
When you use the Router in your network (Figure 2), it becomes your connection to the Internet. Connections can be made directly to the Router, or to an OfficeConnect Switch or Hub, expanding the number of computers you can have in your network.

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.

CHAPTER 2: HARDWARE INSTALLATION
When positioning your Router, ensure:
It is out of direct sunlight and away from sources of heat. Cabling is away from power lines, fluorescent lighting fixtures, and sources of electrical noise such as radios, transmitters and broadband amplifiers. Water or moisture cannot enter the case of the unit. Air flow around the unit and through the vents in the side of the case is not restricted. 3Com recommends you provide a minimum of 25 mm (1 in.) clearance.

Using the Rubber Feet

Use the four self-adhesive rubber feet to prevent your Router from moving around on your desk or when stacking with other flat top OfficeConnect units. Only stick the feet to the marked areas at each corner of the underside of your Router. If you are stacking your Router with other OfficeConnect units, install the Router at the top of the stack. Refer to the documentation supplied with your other OfficeConnect unit for details on using the stacking clip. A stacking clip is not supplied with the Router. Use the stacking clip supplied with another stackable OfficeConnect unit.

Stacking the Router

Wall Mounting
There are two slots on the underside of the Router that can be used for wall mounting. When wall mounting the unit, ensure that it is within reach of the power outlet. You will need two suitable screws to wall mount the unit. To do this: 1 Ensure that the wall you use is smooth, flat, dry and sturdy and make two screw holes which are 150 mm (5.9 in.) apart. 2 Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) clear of the wall surface. 3 Remove any connections to the unit and locate it over the screw heads. When in line, gently push the unit on to the wall and move it downwards to secure.
Before you Install your Router
When making connections, be careful not to push the unit up and off the wall. CAUTION: Only wall mount single units, do not wall mount stacked units.
Before you install and configure your Router, you need the following additional information. If you do not have this information, contact your Internet Service Provider (ISP). Space is provided below for you to record this information. If you have a DSL connection and your ISP allocates IP information dynamically over PPPoE, you need a User Name and Password: PPPoE User Name PPPoE Password PPPoE Service Name : ______________________ : ______________________ : ______________________
You only need a PPPoE Service Name if your ISP requires one. Do not enter anything if your ISP does not require this information. If you have a DSL connection and your ISP allocates IP information dynamically over PPTP, you need a User Name, Password and PPTP Server Address: PPTP User Name PPTP Password PPTP Server Address : ______________________ : ______________________ : ____.____.____.____

SETTING UP YOUR COMPUTERS
The Router has the ability to dynamically allocate network addresses to the computers on your network, using DHCP. However, your computers need to be configured correctly for this to take place. To change the configuration of your computers to allow this, follow the instructions in this chapter. If your computers are configured with fixed or static addresses and you do not wish to change this, then you should use the Discovery program on the Router CD-ROM to detect and configure your Router. Refer to Appendix A for information on using the Discovery program.

Encryption

When setting up wireless networks, it is important to remember that with encryption disabled, anyone with a Wireless PC can eavesdrop on your network. 3Com recommends that you get the network working with encryption disabled first and then enable it as the last step. This will simplify setting up your network. You can configure wireless security such as WEP or WPA encryption on this screen. Note: it is recommended that you use WPA encryption over WEP if your wireless clients support WPA All of the wireless clients must use the same security settings in order to connecdt to the router.
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.

The Router comes with a 14-day free trial of the 3Com Content Filter Service. To activate the 14-day free trial of the service, you must first register your Router at www.3com.com. To continue using the service after the trial period, you must purchase the Full 3Com Content Filter Service(3CS8CFS). URL Filtering rules supersede content filtering rules. If the 3Com Content Filter is blocking certain Web sites that you want to allow, you can add these sites to URL Filter's allow list.

Power LED or Power Adapter OK LED Not Lit
Speed of connection: The 802.11b and 802.11g standards will automatically choose the best speed depending on the quality of your connection. As the signal quality weakens then the speed falls back to a lower speed. The speeds supported by 802.11g are 54 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, and 6 Mbps. The speeds supported by 802.11b are 11 Mbps, 5.5 Mbps, 2 Mbps and 1 Mbps. In general the closer you are to the Router the better the speed. If you are not achieving the speed you had anticipated then try moving the antenna on the Router or moving the Wireless computer closer to the Router. In an ideal network the Router should be located in the centre of the network with Wireless computers distributed around it. Applications are generally available with the computer wireless card to carry out a site survey. Use this application to find the optimal siting for your wireless computer. Consult your Computer Card documentation and vendor for more details.
Check that your Router is receiving power by looking at the status of the Power LED on the front panel and the Power Adapter OK LED on the rear panel:
If both LEDs are lit green then the unit is receiving power. If both LEDs are unlit then no power is being supplied to the unit. Check that the power adapter is plugged into a working mains outlet and that the mains outlet is supplying power. If the mains socket is supplying power then the power adapter or power adapter connection may be faulty. See Replacement Power Adapters below. If the Power Adapter OK LED is lit but the Power LED is unlit then there may be a fault with your unit. Contact 3Com Technical Support.
Check that you are using the correct power adapter for your Router. You should only use the power adapter supplied with your Router.
Replacement Power Adapters
If both the Power Adapter OK LED and Power LED are off, check your power adapter connection. If the mains outlet is working and is capable of supplying power to other devices, contact 3Com Technical Support and ask for a replacement power adapter. Please quote the power adapter part number shown on the OfficeConnect power adapter you are using.

Protocol

Point-to-Point Tunneling Protocol is a method of secure data transmission between two remote sites over the internet. Routing Information Protocol. RIP allows an administrator to set up routing information on one RIP enabled device, and have that routing information replicated to all RIP enabled devices on the network. A standard connector used to connect Ethernet networks. The RJ stands for registered jack. A computer in a network that is shared by multiple end stations. Servers provide end stations with access to shared network services such as computer files and printer queues. Stateful Packet Inspection. This feature requires the firewall to remember what outgoing requests have been sent and only allow responses to those requests back through the firewall. This way, un-requested attempts to access the network will be denied. Service Set Identifier. Some vendors of wireless products use SSID interchangeably with ESSID. An extension of the IP addressing scheme that allows a site to use a single IP network address for multiple physical networks. A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must assigned by InterNIC). A network that is a component of a larger network. A device that interconnects several LANs to form a single logical LAN that comprises of several LAN segments. Switches are similar to bridges, in that they connect LANs of a different type; however they connect more LANs than a bridge and are generally more sophisticated.

TCP/IP

Transmission Control Protocol/Internet Protocol. This is the name for two of the most well-known protocols developed for the interconnection of networks. Originally a UNIX standard, TCP/IP is now supported on almost all platforms, and is the protocol of the Internet. TCP relates to the content of the data travelling through a network ensuring that the information sent arrives in one piece when it reaches its destination. IP relates to the address of the end station to which data is being sent, as well as the address of the destination network.
