Wireless 5G(wl0) & 2.4G(wl1) – Advanced for 2.4G Wireless
sideband) the carrier frequency, within which fall the spectral components produced by modulation of
a carrier wave.
802.11n Rate: This allows you to select the fixed transmission rate or auto.
802.11n Protection: turn off for maximize throughput.
Support 802.11n Client Only: turn on the option to only provide wireless access to the clients
operating at 802.11n speeds.
RIFS Advertisement: Reduced Inter-frame Spacing (RIFS) is an 802.11n feature that also improves
performance by reducing the amount of dead time required between OFDM transmissions. Select Off
to disable this function or auto to enable this function.
OBSS Co-Existence: coexistence (or not) between 20 MHZ and 40 MHZ overlapping basic service
sets (OBSS) in wireless local area networks.
RX Chain Power Save: Enabling this feature turns off one of the Receive chains, going from 2x2 to
2x1 to save power.
RX Chain Power Save Quiet Time: The number of seconds the traffic must be below the PPS value
before the Rx Chain Power Save feature activates itself.
RX Chain Power Save PPS: The maximum number of packets per seconds that can be processed by
the WLAN interface for duration of Quiet Time, described above, before the Rx Chain Power Save
feature activates itself.
54g™ Rate: Available after changing 802.11n Rate to "Use 54g Rate" in 802.11n Rate. It is used to
limit 11n speed to a specific rate, e.g. 1M, 6M, 12M, 24M, 48M, etc.
Multicast Rate: Setting for multicast packets transmission rate.
Basic Rate: Setting for basic transmission rate. It is not a specific kind of rate, it is a series of rates
supported. When set to Default, the router can transmit with all kinds of standardized rates.
Fragmentation Threshold: A threshold (in bytes) whether the packets will be fragmented and at what
size. Packets succeeding the fragmentation threshold of 802.11n WLAN will be split into smaller units
suitable for circuit size. While the packets smaller than fragmentation threshold will not be fragmented.
Default is 2346, setting the fragmentation too low may result in poor performance.
RTS Threshold: Request to Send (RTS) threshold specifies the packet size, when exceeds the size,
the RTS/CTS will be triggered. The default setting of 2347(max length) will disable the RTS.
DTIM Interval: Delivery Traffic Indication Message (DTIM). The entry range is a value between 1 and
255. A DTIM is 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.
Beacon Interval: The amount of time between beacon transmissions in is milliseconds. The default is
100ms and the acceptable is 1- 65535. The beacon transmissions identify the presence of an access
point.
Global Max Clients: Here you have the option of setting the limit of the number of clients who can
connect to your wireless network.
XPress™ Technology: It has been designed to improve the wireless network efficiency. Default is
disabled.
Transmit Power: select the transmitting power of your wireless signal.
