A wireless network is a group of computers, each equipped with one wireless adapter, Computers in a wireless network must be configured to share the same radio channel. Several PCs equipped with wireless cards or adapters can communicate with one another.
The Wireless Broadband Router (Linksys WRT54G2) has been designed for use with 802.11g and 802. products.
(Refer to http://en.wikipedia.org/wiki/IEEE_802.11)) IEEE 802.11 is a set of standards carrying out wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands. They are implemented by the IEEE LAN/MAN Standards Committee (IEEE 802).

- Change the default wireless network name or SSID
- Change the default password
- Enable MAC address filtering
The MAC address is a unique series of numbers and letters assigned to every networking device.
With MAC address filtering enabled, wired network access is provided solely for wireless devices
with specify the MAC address of each computer so that only those computers can access your
wireless network.

- Enable encryption
Encryption protects data transmitted over a wireless network. Wi-Fi Protected Access
(WPA/WPA2) and Wired Equivalency Privacy (WEP) offer different levels of security for wireless
communication.
A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP,
because WPA/WPA2 use dynamic key encryption. To protect the information as it passes over the
airwaves, you should enable the highest level of encryption supported by your network equipment.
WEP is an older encryption standard and may be the only option available on some older devices
that do not support WPA.

- To create a DDNS account
- Dynamic DNS (DDNS) allows you to create a hostname that points to your dynamic IP address
- DDNS client is used to update the hostname information on DDNS server
- It provides an easy to remember URL for quick access.
- DDNS service providers http://www.noip.com/
- Open account on http://www.noip.com/
- Please create one new hostname for web Redirect
- Web Redirect is used to redirect the hostname you created to any URL you selected.
- Enter your new hostname and select a domain name. (In No-IP Free Domains only)
- Select Host Type: Web Redirect
- Enter Redirect URL: https://www.eee.hku.hk/~andy
- Click Add Host to create new DDNS hostname
- Start a browser to browse the new DDNS hostname and check that it can be either redirected to the website or not?
