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 : ______________________ : ______________________ : ____.____.____.____
If your ISP allocates fixed or static IP information, you need the following information: IP Address Subnet Mask Default Router address DNS address : ____.____.____.____ : ____.____.____.____ : ____.____.____.____ : ____.____.____.____

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

Choose the time zone that is closest to your actual location. The time zone setting is used by the system clock when displaying the correct time in the log files. If you use Daylight saving tick the Enable Day Light savings box, and then click Save. The Router reads the correct time from NTP servers on the Internet and sets its system clock accordingly. The Daylight Savings option merely advances the system clock by one hour. It does not cause the system clock to be updated for daylight savings time automatically.

Connecting to the Internet
If you can browse to the Router configuration screens but cannot access sites on the Internet, check the following:
Confirm that the physical connection between the Router and the cable/DSL modem is OK, and that the link status LEDs on both Router and modem are illuminated. Confirm that the connection between the modem and the cable/DSL interface is OK. Ensure that you have entered the correct information into the Router configuration screens as required by your Internet Service Provider. Use the Internet Settings screen to verify this. For DSL users, check that the PPPoE or PPTP user name, password and service name are correct, if these are required. Only enter a PPPoE service name if your ISP requires one. For cable users, check whether your ISP requires a fixed MAC (Ethernet) address. If so, use the Clone MAC Address feature in the Router to ensure that the correct MAC address is presented. For cable users, check whether your ISP requires a fixed Host Name. If so, enter the required Host Name in the Internet Settings screen. Ensure that your computers are not configured to use a Web proxy. On Windows computers, this can be found under Control Panel > Internet Options > Connections.
Forgotten Password and Reset to Factory Defaults
If you can browse to the Router configuration screen but cannot log on because you do not know or have forgotten the password, follow the steps below to reset the Router to its factory default configuration. CAUTION: All your configuration changes will be lost, and you will need to run the configuration wizard again before you can re-establish your Router connection to the Internet. Also, other computer users will lose their network connections whilst this process is taking place, so choose a time when this would be convenient. 1 Remove power from the Router. 2 Disconnect all your computers and the cable/DSL modem from the Router. 3 Using a straight through Ethernet cable, connect the Ethernet Cable/DSL port on the rear of the Router to any one of the LAN ports. 4 Re-apply power to the Router. The Alert LED will flash as the Router starts up, and after approximately 30 seconds will start to flash more slowly (typically 2 seconds on, 2 seconds off). Once the Alert LED has started to flash slowly, remove power from the Router. 5 Remove the cable connecting the Cable/DSL port to the LAN port, and reconnect one of your computers to one of the Router LAN ports. 6 Re-apply power to the Router, and when the start-up sequence has completed, browse to:

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

This type of IP Address operates on a subnet mask of 255.255.255.0. See an example about how a network with three computers and a Router might be configured.
Table 4 IP Addressing and Subnet Masking
Device PC 1 PC 2 PC 3 Router IP Address 192.168.100.8 192.168.100.33 192.168.100.188 192.168.100.72 Subnet Mask 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0
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.

95 and Windows 98 will call the server to obtain the address. Windows 98 will allocate itself an address if no DHCP server can be found. DNS Server Address DNS stands for Domain Name System, which allows Internet host computers to have a domain name (such as 3com.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a domain name is requested (as in typing 3com.com into your Internet browser), the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned. DSL stands for digital subscriber line. A DSL modem uses your existing phone lines to send and receive data at high speeds. A method for providing a level of security to wireless data transmissions. The OfficeConnect Cable/DSL Router and Wireless Cable/DSL Router offer a choice of encryption methods. See WPA and WEP for details. Extended Service Set Identifier. The ESSID is a unique identifier for your wireless network. You must have the same ESSID entered into the Router and each of it's wireless clients. A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet networks use CSMA/CD to transmit packets at a rate of 10 Mbps over a variety of cables. See MAC address. An Ethernet system that is designed to operate at 100 Mbps. Electronic protection that prevents anyone outside of your network from seeing your files or damaging your computers. A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link.
