WEP Open System – The VAP broadcasts a beacon signal including the
configured SSID. Wireless clients with an SSID setting of “any” can read the SSID
from the beacon and automatically set their SSID to allow immediate
connection.
■
WEP Key – WEP is used to encrypt data transmitted between wireless
clients and the VAP. WEP uses static shared keys (fixed-length hexadecimal
or alphanumeric strings) that are manually distributed to all clients that
want to use the network.
WEP is the security protocol initially specified in the IEEE 802.11 standard
for wireless communications. Unfortunately, WEP has been found to be
seriously flawed and cannot be recommended for a high level of network
security. For more robust wireless security, the access point provides Wi-Fi
Protected Access (WPA) and WPA2 for improved data encryption and user
authentication.
Be sure that the WEP shared keys are the same for each client in the wireless
network. All clients share the same keys, which are used for data
encryption.
For 64-bit WEP, string length must be 5 ASCII characters (letters and
numbers) or 10 hexadecimal digits. For 128-bit WEP, string length must be
13 ASCII characters (letters and numbers) or 26 hexadecimal digits.

WEP Shared Key – The VAP broadcasts a beacon signal including the
configured SSID. Wireless clients with an SSID setting of “any” can read the SSID
from the beacon and automatically set their SSID to allow immediate
connection if the WEP keys set by the client matches those set on the AP. When
using this encryption option, the WEP keys are used both to authenticate the
client and to encrypt the data transmitted.

WEP Key – WEP is used to authenticate wireless clients and encrypt data
transmitted between clients and the VAP. WEP uses static shared keys
(fixed-length hexadecimal or alphanumeric strings) that are manually
distributed to all clients that want to use the network.

WPA-PSK – For enterprise deployment, WPA requires a RADIUS authentication
server to be configured on the wired network. However, for small office
networks that may not have the resources to configure and maintain a RADIUS
server, WPA provides a simple operating mode that uses just a pre-shared
password for network access. The Pre-Shared Key mode uses a common
password for user authentication that is manually entered on the access point
and all wireless clients. The PSK mode uses the same TKIP packet encryption
