Description
Enable Wireless
A checkbox that enables or disables the wireless LAN
interface.
When selected, the Web UI displays Hide Access
point, SSID, and County settings. The default is Enable
Wireless.
Hide Access Point
Select Hide Access Point to protect ADSL router access point
from detection by wireless active scans. If you do not want
the access point to be automatically detected by a wireless
station, this checkbox should be de-selected.
The station will not discover this access point. To connect a
station to the available access points, the station must
manually add this access point name in its wireless
configuration.
In Windows XP, go to the Network>Programs function to view
all of the available access points. You can also use other
software programs such as NetStumbler to view available
access points.
SSID
Sets the wireless network name. SSID stands for Service Set
Identifier.
All stations must be configured with the correct
SSID to access the WLAN. If the SSID does not match, that
user will not be granted access.
The naming conventions are: Minimum is one character and
maximum number of characters: 32 bytes.
BSSID
The BSSID is a 48bit identity used to identify a particular BSS
(Basic Service Set) within an area. In Infrastructure BSS
networks, the BSSID is the MAC (Medium Access Control)
address of the AP (Access Point) and in Independent BSS or ad
hoc networks, the BSSID is generated randomly.
Country
A drop-down menu that permits worldwide and specific
national settings. Each county listed in the menu enforces
specific regulations limiting channel range:
z
US= worldwide
z
Japan=1-14
z
Jordan= 10-13
z
Israel= 1-13
Enable Guest SSID
CT-5372 supports multiple SSIDs. Guest SSID is not visible.
The wireless hosts are able to scan main SSID only.

Security
Security options include authentication and encryption services based on the wired
equivalent privacy (WEP) algorithm. WEP is a set of security services used to
protect 802.11 networks from unauthorized access, such as eavesdropping; in this
case, the capture of wireless network traffic. When data encryption is enabled,
secret shared encryption keys are generated and used by the source station and the
destination station to alter frame bits, thus avoiding disclosure to eavesdroppers.
802.11 supports two subtypes of network authentication services: open system and
shared key. Under open system authentication, any wireless station can request
authentication. The system that needs to authenticate with another wireless
station sends an authentication management frame that contains the identity of the
sending station. The receiving station then sends back a frame that indicates
whether it recognizes the identity of the sending station.
Under shared key authentication, each wireless station is assumed to have
received a secret shared key over a secure channel that is independent from 802.11
wireless network communications channel.
The following screen appears when Security is selected. The Security page allows
you to configure security features of the wireless LAN interface. You can set the
network authentication method, selecting data encryption, specify whether a
network key is required to authenticate to this wireless network and specify the
encryption strength.

Sets the wireless network name. SSID stands for Service Set

Network
Authentication
It specifies the network authentication. When this checkbox is
selected, it specifies that a network key be used for authentication to
the wireless network. If the Network Authentication (Shared mode)
checkbox is not shared (that is, if open system authentication is
used), no authentication is provided.
Open system authentication
only performs identity verifications.
Different authentication type pops up different settings requests.
Choosing
802.1X
, enter RADIUS Server IP address, RADIUS Port,
and RADIUS key.
Also, enable WEP Encryption and the Encryption Strength.
Select the Current Network Key and enter 13 ASCII characters or 26
hexadecimal digits for 128-bit encryption keys and enter 5 ASCII
characters or 10 hexadecimal digits for 64-bit encryption keys.
Choosing
WPA
, you must enter WPA Group Rekey Interval.

Choosing
WPA-PSK
, you must enter WPA Pre-Shared Key and
Group Rekey Interval.
WEP
Encryption
It specifies that a network key is used to encrypt the data is sent over
the network. When this checkbox is selected, it enables data
encryption and prompts the Encryption Strength drop-down menu.
Data Encryption (WEP Enabled) and Network Authentication use the
same key.
Encryption
strength
A session’s key strength is proportional to the number of binary bits
comprising the session key file. This means that session keys with a
greater number of bits have a greater degree of security, and are
considerably more difficult to forcibly decode. This drop-down
menu sets either a 64 8-bit (5-ASCII character or 10-hexadecimal
character) or 128 8-bit (13-ASCII character or 26-hexadecimal
character) key.
If you set a minimum 128-bit key strength, users attempting to
establish a secure communications channel with your server must
use a browser capable of communicating with a 128-bit session key.
The Encryption Strength settings do not display unless the network
Authentication (shared Mode) check box is selected.
