Using shared WEP keys
The Nokia A032 can store up to four shared
WEP keys simultaneously.
An access point only transmits data using one
of the shared WEP keys – the active key – but
can receive data from clients using any of the
four shared WEP keys it knows about:
As you can see from the figure above, the
active key (denoted by the asterisk *) does not
have to be the same on each client, but each
client’s active key must be recognized by the
access point.
The active shared WEP key is also used to
transmit broadcast and multicast frames even
to wireless clients which are using personal
WEP keys for normal data. This means that
even if you are using personal WEP keys, you
should always define at least one active shared
(default) key to the access points and wireless
clients.
Changing a shared WEP key
Having a pool of shared WEP keys makes it
easy to change a key without disrupting
network operation:
