System Requirements
Before starting, you must ensure the following:
●
You already have a cable or DSL broadband connection to the Internet, with
a suitable modem, and that this connection works properly. The modem
must have an Ethernet port for connection to your Router.
●
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 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.
