System Requirements

Before starting, you must ensure the following:

You already have an ADSL broadband account.

You have a computer that has an Ethernet connection available and is already correctly configured for communication with the Internet. Your

computer must be able to connect to the Internet via the modem, and must have a Web browser installed.

There are no other DHCP server devices on your local network that are responsible for allocating IP addresses to your computers and other network- connected devices. Your Router will now perform this function by default.

If you require wireless access you have a computer with a wireless 802.11b or 802.11g adapter card installed.

If one or more of these conditions are not met, refer to the comprehensive Router User Guide provided on the accompanying CD-ROM for further guidance.
