When you select to enable encryption and deny non-encrypted data, your
Radio Link Module will:
• Only process messages received at its wireless interface, when the
messages have been encrypted with either one of the four identified
keys.
• Always transmit wireless data using the selected WEP key.
• Also encrypt all its multicast and broadcast traffic that it will transmit to
the wireless medium.
If your network includes wireless stations configured with a non-matching
WEP key, or equipped with PC Cards that do not support WEP encryption,
such stations will not be able to establish a wireless connection because
they will not be able to understand (decrypt) crucial network information.

check box, the RLM will:
• Process all messages received at its wireless interface, regardless
whether the messages have been encrypted with one of the identified
keys or not.
• Encrypt wireless transmissions based on the encryption settings of the
addressed station.
• If the addressed station does use WEP encryption, the Radio Link
Module will send the message in encrypted format, using the selected
transmit key value.
