Description
Select 20GHz or 40GHz bandwidth. 40GHz bandwidth uses two
adjacent 20GHz bands for increased data throughput.
Select Upper or Lower sideband when in 40GHz mode.
Set the physical transmission rate (PHY) from 6.5 to 130 Mbps.
Turn Off for maximized throughput.
Turn On for greater security.
Turn Off to allow 802.11b/g clients access to the router.
Turn On to prohibit 802.11b/g clients access to the router.
Drop-down menu that specifies the following fixed rates:
Auto: Default. Uses the 11 Mbps data rate when possible but
drops to lower rates when necessary. 1 Mbps, 2Mbps,
5.5Mbps, or 11Mbps fixed rates. The appropriate setting is
dependent on signal strength.
Setting for multicast packet transmit rate (1-54 Mbps)
Setting for basic transmission rate.
A threshold, specified in bytes, that determines whether
packets will be fragmented and at what size. On an 802.11
WLAN, packets that exceed the fragmentation threshold are
fragmented, i.e., split into, smaller units suitable for the circuit
size. Packets smaller than the specified fragmentation
threshold value are not fragmented. Enter a value between
256 and 2346. If you experience a high packet error rate, try to
slightly increase your Fragmentation Threshold. The value
should remain at its default setting of 2346. Setting the
Fragmentation Threshold too low may result in poor
performance.
Request to Send, when set in bytes, specifies the packet size
beyond which the WLAN Card invokes its RTS/CTS mechanism.
Packets that exceed the specified RTS threshold trigger the
RTS/CTS mechanism. The NIC transmits smaller packet
without using RTS/CTS. The default setting of 2347
(maximum length) disables RTS Threshold.
Delivery Traffic Indication Message (DTIM) is also known as
Beacon Rate. The entry range is a value between 1 and
65535. A DTIM is a countdown variable that informs clients of
the next window for listening to broadcast and multicast
messages. When the AP has buffered broadcast or multicast
messages for associated clients, it sends the next DTIM with a
DTIM Interval value. AP Clients hear the beacons and awaken
to receive the broadcast and multicast messages. The default
is 1.
The amount of time between beacon transmissions in
milliseconds. The default is 100 ms and the acceptable range
is 1 – 65535. The beacon transmissions identify the presence
of an access point. By default, network devices passively scan
all RF channels listening for beacons coming from access
points. Before a station enters power save mode, the station
needs the beacon interval to know when to wake up to receive
the beacon (and learn whether there are buffered frames at the
access point).
