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.

IEEE

The Institute of Electrical and Electronics Engineers. The IEEE sets standards for

networking, including Ethernet LANs. IEEE standards ensure interoperability between

systems of the same type.
