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.
