What is a Router?
 An electronic device that connects a local
area network (LAN) to a wide area network
(WAN) and handles the task of routing
messages between the two networks.
 LAN - Local Area Network (your home)
 WAN - Wide Area Network (your ISP or the
internet)
But, what does it do?
 The router for your home allows you to
share an internet connection with multiple
computers without having to use a computer
that acts as a "gateway".
 Gateway - computer that acts as a "host"
computer
Yeah, but what does a router do?
 It sits between your modem and your computer or your
network. It is difficult to hack your computer or your
network when it is hidden behind a hardware box.
 Modem - A device that adapts a terminal or computer to a
voice-grade telephone line.
 Hack is usually a technique used to subvert, misuse or
subtly change a program, gadget or mechanism in such a
way as to change, or add to, its functionality.
Why do I want a router?
 A router is the controller of your network.
(POLICEMAN) It has multiple functions, all of
which together allow your network to operate.
 The router has a FIREWALL - keeping hackers
from attempting to connect to your computer from
the outside.
 Firewall - A firewall is a system that secures a
network, shielding it from access by unauthorized
users.
Firewall?
 There are two basic types of firewalls.
 Software – You load the program onto your
computer
 Hardware – This type comes pre-loaded in a
box (like a router).
How does a firewall work?
 A firewall may allow all traffic through unless
it meets certain criteria, or it may deny all
traffic unless it meets certain criteria.
 A firewall will not stop virus’, Trojans or other
parasites.
What type of routers are there?
 Wired – Must use a cat 5 cable. Can normally
connect up to 4 computers. (More if you use a
switch)
– Starting at approx. $40
 Wireless – Just like wired only it also has an
antenna for transmitting radio waves to a wireless
receiver. Can connect 4 wired and endless
wireless.
– Starting at approx. $100

How do I set up my router?
 Normally, you just plug the router into the
modem and the computers into the router.
The default settings are usually good
enough.
 You will have to power cycle both the
modem and router.
