Infrastructure
To communicate with an AP, the SSID of the client must match
the SSID of the access point. The channel is set on "automatic".
The Default Access Point (DAP) does not need to be specified.
Setting a DAP value is only necessary in the roaming scenario
where there are more than one AP with the same SSID. The client
can connect to any of these AP. However, whenever possible, it
will automatically connect to the AP being specified as DAP.
Ad Hoc
Ad Hoc is designed as a peer-to-peer communication mode. In
Ad Hoc mode, the SSID between clients must match for
communication to be possible. The first client to start an Ad Hoc
session will set a “communicating” channel. All subsequent
clients that wish to communicate with this first client will
automatically be tuned to match the first client’s
“communicating” channel. The channel set in their own
configuration will be ignored unless the channels match.
WEP Security
WEP security allows the access point to verify the client
authentication before communication takes place. The WEP
encryption key can either be 40 bits (5 pairs of hex) or 128 bits
(13 pairs of hex). These keys can take any values as long as they
are hex, they are not case sensitive, and they match exactly
between the access point and the clients.
Open Authentication and Shared Key Authentication are the two
authentication modes. The access point and client authentication
modes must match for any communication to take place. A
session between the client and the AP can be broken into two
stages, authentication and communication. Authentication is
when the AP authenticates the client. Communication is when the
two actually exchange data. Under Open Authentication mode,
the AP will authenticate the client regardless of the WEP key,
thus the client and the AP will always associate. Communication
will take place only if the WEP keys between the client and the
AP match. Shared Key Authentication, on the other hand,
requires that the WEP key has to match in order for the AP to
authenticate and communicate with the client.
