A wireless router allows devices to connect to a network wirelessly. It performs the functions of a router and wireless access point, connecting wired and wireless devices and providing Internet access. The router encodes and decodes signals to transmit data between connected devices and external networks. When setting up a wireless router, it is important to change default passwords, choose strong encryption like WPA2, and consider the router's range, speed and compatibility standards.

3. What is a wireless router?
• A wireless router is a device that
performs the functions of a router
but also includes the functions of a
wireless access point. It is commonly
used to provide access to the
Internet or a computer network. It
does not require a wired link, as the
connection is made wirelessly, via
radio waves.

4. • It can function in a wired LAN

5. in a wireless-only LAN (WLAN),

6. or in a mixed wired/wireless network, depending on the
manufacturer and model.

7. How does it work ?
• A wireless router must be connected to a network or Internet
connection and serves as a bridge or gateway for the client devices
that access the router. For most consumers, a wireless router is
connected directly to a DSL (Digital Subscriber Line) or cable
Internet connection via Ethernet or USB connection.

8. Cont..
• The router decodes information received
from client computers from the RF signal
to the appropriate network datagram to be
sent to computer hosts on the local or
external network.
• Wireless routers also receive and encode
data received from the Internet to transmit
to the appropriate device on the local
wireless network.

9. Cont..
• The operation of a wireless network is similar to
that used in two-way radio communication
systems with the router providing the
mechanism for all network operations by the
local computer hosts.

10. How to secure a router?
• The first thing you should do when setting up
your wireless network is change the name of
your router as well as the default login name and
password.

11. Cont..
• Secondly, you should ensure you choose an
appropriate level of encryption. WEP (Wired
Equivalent Privacy) has been shown to be easily
cracked and should be avoided if possible.

12. Cont..
• WPA (Wi-Fi Protected Access) is a more
secure method though not entirely
uncrackable,

13. Cont..
• WPA II, the latest generation of this encryption
standard, is recommended. Any device that
connects to your wireless network - whether a
laptop, mobile phone - will need to support WPA
II as well.

14. How to choose a router?
• When you're choosing a wireless router,
you should consider the same things as
you would with any other wireless
equipment: range, speed and standards.
