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. PPPoE (DSL only) If the installation instructions that accompany your modem ask you to install a PPPoE client on your PC then select this option. Note that when you install the Router, you will not need to use the PPPoE software on your PC. To configure the Router you will need to know the following: Username, Password, and Service Name (if required by your ISP). 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 Address, and DNS address(es). PPTP (DSL or Cable) PPTP is only used by some European providers. If the installation instructions that accompany your modem ask you to setup a dialup connection using a PPTP VPN tunnel then select this option. Note that when you install the Router, you will not need to use the dialup VPN on your PC anymore. To configure the Router you will need to know the following: Username, Password, Service Name (if required by your ISP), and VPN Server address (usually your modem). 1. 2. 3. 4. 5. 6. If you haven’t already done so, restart your computer. Launch your web browser and attempt to contact the Router by typing the following URL in the location bar: 192.168.1.1. If you can access the Login page, then your computer has correctly received an IP address from the Router. Login using the default password admin. The Wizard will attempt to launch automatically, but if it fails, select the Wizard tab and click on the Wizard… button. Where possible, the Wizard will recommend settings for most parameters. However, there are some settings which you must provide. Most of these will have been provided to you by your ISP when you set the account up. By default, 3Com recommends that you leave the LAN IP address for the Router as 192.168.1.1. However, if you should choose to change it, make a note of the new address Router’s LAN IP Address When the DHCP Server Settings page is displayed, make sure that the Enable the DHCP Server with the following settings option is selected. If you are experiencing difficulties with your installation, try the following: • Ensure all networking equipment is switched on. The Router should be showing a green Power LED. If it is not, check the power adapter connection. Do not use any power adapter with your Router other than the one supplied. • Ensure the Cable/DSL Modem is connected. The Router should be displaying a green or yellow Cable/DSL Status LED. If no LED is displayed, check that your modem is switched on and that it is connected to the Cable/DSL port with an Ethernet cable. • Ensure that the computer is connected to the Router. The Router should be displaying a green or yellow LAN Status LED. If it is not, check that the computer is connected to one of the Router’s LAN ports with an Ethernet cable. • Ensure your computer is configured correctly. Make sure that the computer obtains an IP address automatically. See Section 2 for details. Ensure that the NIC card is configured for autonegotiation. • Ensure that you do not have a web proxy enabled on your computer. Go to the Control Pane/ and click on Internet Options. Select the Connections tab and click on the LAN Settings button at the bottom. Make sure that the Use Proxy Server option is unchecked. • If you are unable to access the Router’s Web interface.
