When Xpress is turned on, aggregate throughput can
improve significantly.
The 802.11g standards provide a protection method so
802.11g and 802.11b devices can co-exist in the same
network without "speaking" at the same time. Do not disable
802.11n protection if there is a possibility that 802.11b or
802.11g devices will use your wireless network. In Auto
mode, the wireless devices use RTS/CTS to improve
802.11n performance in mixed 802.11g/802.11b networks.
Turn protection off to maximize 802.11n throughput under
most conditions.
Provides compatibility with certain devices that do not meet
802.11 specifications.
Select the wireless transmission rate to a particular speed
or leave it as default (Auto) to allow the AP adjusts speed
automatically.
Specify the rate at which multicast packets are transmitted
and received on your wireless network. Multicast packets
are used to send a single message to a set of recipients in a
defined group. Teleconferencing, videoconferencing and
group email are some examples of multicast applications.
Specifying a high multicast rate may improve performance
of multicast features. The rates are in Mbps. You can select
Automatic, 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48 and 54.
Set the Physical Layer (NPHY) rate. These rates are only
applicable when the 802.11n mode is configured as
Automatic.
A beacon is a packet broadcast by the router to synchronize
the wireless network. The default interval is 100 ms.
Interval of the Delivery Traffic Indication Message (DTIM). A
DTIM field is a countdown field informing clients of the next
window for listening to broadcast and multicast messages.
When the router has buffered broadcast or multicast for
associated clients, it sends the next DTIM with a DTIM
Interval value. Its clients hear the beacons and awaken to
receive the broadcast and multicast message. The default
value is 1.
