P-2602HWNLI Support Notes
SSID is a configurable identification that allows clients to communicate to the appropriate base station.
With proper configuration, only clients that are configured with the same SSID can communicate with
base stations having the same SSID. SSID from a security point of view acts as a simple single shared
password between base stations and clients.
What is an ESSID ?
ESSID stands for Extended Service Set Identifier and identifies the wireless LAN. The ESSID of the
mobile device must match the ESSID of the AP to communicate with the AP. The ESSID is a 32-character
maximum string and is case-sensitive.
How do I secure the data across an Access Point's radio link ?
Enable Wired Equivalency Protocol (WEP) or Wi-Fi Protected Access (WPA) to encrypt the payload of
packets sent across a radio link.
What is WEP ?
Wired Equivalent Privacy. WEP is a security mechanism defined within the 802.11 standard and designed
to make the security of the wireless medium equal to that of a cable (wire). WEP data encryption was
designed to prevent access to the network by "intruders" and to prevent the capture of wireless LAN
traffic through eavesdropping. WEP allows the administrator to define a set of respective "Keys" for each
wireless network user based on a "Key String" passed through the WEP encryption algorithm. Access is
denied by anyone who does not have an assigned key. WEP comes in 40/64-bit and 128-bit encryption
key lengths. Note, WEP has shown to have fundamental flaws in its key generation processing.
What is the difference between 40-bit and 64-bit WEP ?
40 bit WEP & 64 bit WEP are the same encryption level and can interoperate. The lower level of WEP
encryption uses a 40 bit (10 Hex character) as "secret key" (set by user), and a 24 bit " Initialization
Vector " (not under user control) (40+24=64). Some vendors refer to this level of WEP as 40 bit, others as
64 bit.
What is a WEP key ?
A WEP key is a user defined string of characters used to encrypt and decrypt data.
