802.11 Authentication
The 802.11 standard defines several services that govern how two 802.11 devices communicate. 
The following events must occur before an 802.11 Station can communicate with an Ethernet 
network through an access point such as the one built in to the WGR614 v4:
1.Turn on the wireless station.
2.The station listens for messages from any access points that are in range.
3.The station...

Shared Key Authentication
The following steps occur when two devices use Shared Key Authentication:
1.The station sends an authentication request to the access point.
2.The access point sends challenge text to the station.
3.The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and 
sends the encrypted text to the access...

Overview of WEP Parameters
Before enabling WEP on an 802.11 network, you must first consider what type of encryption you 
require and the key size you want to use. Typically, there are three WEP Encryption options 
available for 802.11 products:
1. Do Not Use WEP: The 802.11 network does not encrypt data. For authentication purposes, the 
network uses Open System...

Key Size
The IEEE 802.11 standard supports two types of WEP encryption: 40-bit and 128-bit.
The 64-bit WEP data encryption method, allows for a five-character (40-bit) input. Additionally, 
24 factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24 
factory-set bits are not user-configurable). This encryption key will be used to encrypt/decrypt all 
data...

Note: Whatever keys you enter for an AP, you must also enter the same keys for the client adapter 
in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client 
adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc.
Note: The AP and the client adapters can have different default WEP Keys as long as the keys are 
in the same order. In other words, the...

The radio frequency channels used are listed in Ta b l e  7 - 1:
Note: The available channels supported by the wireless products in various countries are different.
The preferred channel separation between the channels in neighboring wireless networks is 25 
MHz (5 channels). This means that you can apply up to three different channels within your 
wireless network. There are only 11 usable wireless...

ADSL
Short for asymmetric digital subscriber line, a technology that allows data to be sent over existing copper 
telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and 
from 16 to 640 Kbps when sending data (known as the upstream rate). 
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world 
gain access.

A Certificate Authority is a trusted third-party organization or company that issues digital certificates used 
to create digital signatures and public-private key pairs. 
The role of the CA in this process is to guarantee that the individual granted the unique certificate is, in fact, 
who he or she claims to be. Usually, this means that the CA has an arrangement with a financial institution, 
such as a credit card...
