DRequired; In this mode, it is mandatory to use shared-key authentication. If open-key authentication is used, a failed authentication will result. When a station uses shared-key authentication, encryption is always used. Default keys are used if no station-specific key exists. Broadcast and multicast data will be encrypted using the default key.
DRequired, Wifi; In this mode, a station may use either open-key or shared-key authentication and in both cases encryption is always used. Default keys are used if no station-specific keys exist. Broadcast and multicast data will be encrypted using the the default key.
DRequired, specific keys; In this mode, a station must use shared-key authentication and station-specific key. If the station uses open-key authentication or station-specific key is not available, a failed authentication will result. Successful shared-key authentication results encryption using the station-specific keys. Broadcast and multicast data will be encrypted using the default key.
In most cases, it is acceptable to use default keys. Most modes also allow concurrent use of station-specific and/or user-specific keys at the same time. Wifi mode provides lower authentication support but it supports all certified WLAN clients. Wifi mode is recommended if other than Nokia wireless LAN cards are used.
Figures 8 and 9 show Wlan Clients page with default key and station-specific keys used, respectively. In Figure 8, the station “PC1” on the Client table uses the default key 1. Additonally, the Client table is used as a MAC address -based access control list. In Figure 9, stations “PC1” and “PC2” use the station-specific key given in the WEP key field on the Client table. The MAC address -based access list is not needed, but the default key is used to encrypt the broadcast/multicast traffic.
Note
If you are using a station-specific key, you must also configure the default key because it is used for broadcast.
