Chapter 16 - Internet Connection Sharing
Before you press the INTERNET button for the first time, you need to make sure that the
SL400i has Internet access. Either directly through a wireless base station, or indirectly through a
PC with Internet access and router/gateway software (e.g. ICS from the Windows OS) installed
and running.
If you connect (either wired or wireless) the SL400i to an existing network host with
Internet access:
Prefered solution:
If you have an existing home network with centrally shared broadband Internet access for all
connected computers, you can connect the SL400i directly to your central network device: the
router/gateway.That way, the SL400i can access the Internet just like your other computers and
you do not need to install ICS to make Internet access available to your SL400i.
If you connect the SL400i (by wires or wireless) to a stand-alone or client PC with Internet
access:
If you connect the Wireless USB adapter to a stand-alone or client PC with an existing
broadband Internet connection, you will need to bridge - within that PC - the wireless or wired
connection that connects to the SL400i, to the existing network adapter that connects to the
Internet.You do this by enabling Internet Connection Sharing (ICS) from your

operating system for that PC.This makes the PC share its existing
broadband Internet connection with the SL400i.
ICS configuration and usage issues
ICS is intended for use in small networks in which the network configuration and the Internet
connection are managed by the Windows-based computer on which the shared connection
resides (the ‘host’ computer). It is assumed that on its network, this computer is the only
Internet connection, it is the only gateway to the Internet, and that it sets up all internal
network addresses (this means it is the DHCP server for the network).
If a network has a central host computer or router that acts as a DHCP server, this server
automatically allocates IP addresses, netmasks, and the gateway address to all DHCP client
computers and devices in the network.
Important notes:
– Only Microsoft Windows98 SE (Second Edition) or higher provides ICS, other operating systems
are not supported.You may try to use other router/gateway software at your own discretion.
–You should only install Internet Connection Sharing on the computer that you use to connect to
the Internet.
– The host computer must remain switched on during Internet access sharing.
– ICS is router/gateway software with Dynamic Host Control Protocol server (DHCP) functionality.
The ICS host computer must be the only DHCP server on the network.
Before installing ICS, first disable any DHCP services that are provided on the network
(e.g. by a hardware router/gateway or base station).
Refer to the router/gateway manufacturer's instructions on how to disable its DHCP services.
