Encryption

This provides wireless data transmissions with a level of security. This option 

allows you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 

10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 

hexadecimal digits or 13 ASCII characters. 

64-bit and 40-bit WEP keys use the same encryption method and can 

interoperate on wireless networks. This lower level of WEP encryption uses 

a 40-bit (10 hexadecimal digits assigned by the user) secret key and a 24-bit 

Initialization Vector assigned by the device. 104-bit and 128-bit WEP keys use 

the same encryption method.

All wireless clients in a network must have identical WEP keys with the access 

point to establish connection. Keep a record of the WEP encryption keys.

Extended Service Set (ESS)

A set of one or more interconnected basic service set (BSSs) and integrated 

local area networks (LANs) can be configured as an Extended Service Set.

ESSID (Extended Service Set Identifier)

You must have the same ESSID entered into the gateway and each of its 

wireless clients. The ESSID is a unique identifier for your wireless network.

Ethernet

The most widely used LAN access method, which is defined by the IEEE 802.3 

standard. Ethernet is normally a shared media LAN meaning all devices on the 

network segment share total bandwidth. Ethernet networks operate at 10Mbps 

using CSMA/CD to run over 10-BaseT cables.

Firewall

A firewall determines which information passes in and out of a network. NAT 

can create a natural firewall by hiding a local network’s IP addresses from the 

Internet. A Firewall prevents anyone outside of your network from accessing 

your computer and possibly damaging or viewing your files.

Gateway

A network point that manages all the data traffic of your network, as well as to 

the Internet and connects one network to another.

ICS

ICS is used to share one computer’s Internet connection with the rest of the 

computers on your network. When this computer is connected to the Internet, 

all the communications to and from the Internet on your network are sent 

through this computer which is called the host computer. The rest of the 

computers can send and receive e-mail messages and access the web as if it 

were connected directly to the Internet.
