• Ensure your power adapter is correctly fitted. If the illuminated logo is not lit, check your power
adapter connections. Ensure the adapter is correctly inserted in to the power socket. Try an alternative
outlet. Check that the power cable connecting the power supply to the Router is not damaged, and
that the connector is correctly inserted into the Router. If the problem persists, it is likely that the
power adapter is faulty. Please contact 3Com for a replacement adapter.
Cable Internet Connections
• Some Cable providers authenticate to the user’s computer MAC address. If this is required, go to
Internet Settings and select Clone the MAC Address. This will copy the MAC address of your computer
onto the Internet port of the Router.
• Some Cable providers authenticate to the user’s Host Name. If this is required, go to Internet Settings
and enter the host name of your computer into the Host Name field.
DSL Internet Connections
• If you have an existing DSL line and have PPPoE or PPTP client software installed on your computer, you
will need to disable it. See section 2.
• If your DSL line uses PPPoE or PPTP, go to Internet Settings and ensure that the correct IP Allocation
mode is selected. Check that your Username and Password are correct.
• Some DSL providers require the use of a PPPoE Service Name. If this is required, go to Internet Settings
and enter the PPPoE Service Name in the field provided. If it is not required, you must leave it blank.
Wireless Configuration
• If you are unable to access the wireless LAN:
• Ensure that the wireless client is set to infrastructure mode.
• If you have a wired and wireless NIC in the same computer, ensure that the wired NIC is disabled. See
section 5 for details.
• Ensure that the Service Area Name (SSID) is the same for the wireless client and the Router.
• Ensure that the Router WiFi LED is on. If not, go to the Wireless Settings menu and enable Wireless
Networking, or press the WiFi button for 3 seconds until the WiFi LED is illuminated.
• Ensure that encryption settings are the same for the wireless client and the Router. If there are
problems, turn wireless encryption off in the client and the Router until you have established a wireless
connection.
