Restarting the Network
Once you’ve set up your computers to work with the router, you must reset the network for the 
devices to be able to communicate correctly. Restart any computer that is connected to the firewall.
After configuring all of your computers for TCP/IP networking and restarting them, and 
connecting them to the local network of your wireless router, you are ready to access and 
configure the router.

This chapter provides an overview of Wireless networking.
Wireless Networking Overview
The wireless router conforms to the Institute of Electrical and Electronics Engineers (IEEE) 
802.11b and 802.11g standards for wireless LANs (WLANs). On an 802.11b or g wireless link, 
data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in 
the unlicensed radio spectrum at 2.5GHz. The maximum data...

Ad Hoc Mode (Peer-to-Peer Workgroup)
In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed 
points to the network - each node can generally communicate with any other node. There is no 
Access Point involved in this configuration. This mode enables you to quickly set up a small 
wireless workgroup and allows workgroup members to exchange data or share printers as...

•Shared Key. With Shared Key authentication, only those PCs that possess the correct 
authentication key can join the network. By default, IEEE 802.11 wireless devices operate in 
an Open System network. 
Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured 
to operate in Shared Key authentication mode. 
802.11 Authentication
The 802.11 standard defines several services...

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....

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...

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 transmitted via the...

WEP Configuration Options
The WEP settings must match on all 802.11 devices that are within the same wireless network as 
identified by the SSID. In general, if your mobile clients will roam between access points, then all 
of the 802.11 access points and all of the 802.11 client adapters on the network must have the same 
WEP settings. 
Note: Whatever keys you enter for an AP, you must also enter the same keys...

Note: The available channels supported by the wireless products in various countries are different. 
For example, Channels 1 to 11 are supported in the U.S. and Canada, and Channels 1 to 13 are 
supported in Europe and Australia.
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...
