WEP
If you choose WEP as the security configuration, you have to specify encryption key (Key 1 ~ Key 4) and authentication mode (open or shared). All wireless devices must support the same WEP encryption bit size and have the same key.
Key1 to Key4 | Four keys can be entered here, but only one key can be selected  | 
  | at a time. The keys can be entered in ASCII or Hexadecimal.  | 
  | Choose the key you wish to use by using the Default Key drop  | 
  | down list.  | 
Authentication Mode | Open - Open system authentication simply consists of two  | 
  | communications. The first is an authentication request by the  | 
  | client that contains the station ID (typically the MAC address).  | 
  | This is followed by an authentication response from the  | 
  | AP/router containing a success or failure message. An example  | 
  | of when a failure may occur is if the client's MAC address is  | 
  | explicitly excluded in the AP/router configuration.  | 
  | Shared - Shared key authentication relies on the fact that both  | 
  | stations taking part in the authentication process have the same  | 
  | "shared" key or passphrase. The shared key is manually set on  | 
  | both the client station and the AP/router. Three types of shared  | 
  | key authentication are available today for home or small office  | 
  | WLAN environments.  |
