Encryption

This provides wireless data transmissions with a level of security. This option allows youtospecifya64-bitora128-bitWEPkey.A64-bitencryptioncontains10hexadecimal digits or 5ASCII characters.A128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters.

64-bit and 40-bit WEPkeys use the same encryption method and can interoperate on wireless networks.This lower level of WEP encryption uses a 40-bit (10 hexadecimal digitsassigned bythe user)secret key anda24-bit Initialization Vectorassigned bythe device. 104-bit and 128-bit WEPkeys 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 localareanetworks(LANs)canbeconfiguredasanExtendedServiceSet.

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

802.3standard. 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

Anetwork point that manages all the data traffic of your network, as well as to the Internetandconnectsonenetworktoanother.

IEEE

The Institute of Electrical and Electronics Engineers. The IEEE sets standards for networking,includingEthernetLANs.IEEEstandardsensureinteroperabilitybetween systemsofthesametype.
