The access points contending for the medium may not be aware of each
other. The RTS/CTS mechanism can solve this hidden node problem. (Default:
2346)
Preamble Length (802.11g and 802.11b only)
—IEEE 802.11 frames begin
with an alternating pattern of 1s and 0s called the preamble, which tells
receiving stations that a frame is arriving. This provides time for the receiving
station to synchronize to the incoming data stream. Enabling the Short
preamble can boost your throughput; however, this can cause interoperability
issues. (Default: Long)

which is shared between two VAPs.

UTHENTICATION
The following types of authentication can be configured:
Open System
(the default)—Allows access to everyone.
Shared Key
—If Shared Key is enabled, Encryption must also be enabled as
described in “Configuring Encryption” on page 58.

E
NCRYPTION
The following types of data encryption are available:
WPA—Wi-Fi Protected Access.
WEP—Wired Equivalent Privacy
Note
: Because of limitations in the Virtual Access Point feature, VAPs on the same
physical interface share the same WEP keys; therefore, the WEP configuration
section applies to both VAPs.
