DESCRIPTION
When set to None, the NBG-416N protects wireless communication
against interference.
Select Auto to let the NBG-416N determine whether to turn this feature
on or off in the current environment.
This field controls the transmission power of the NBG-416N. When using
the NBG-416N with a notebook computer, select a lower transmission
power level when you are close to the AP in order to conserve battery
power.
If you select 40 MHz or Auto 20/40MHz as your Channel Bandwidth
in the Wireless LAN > General screen, the extension channel enables
the NBG-419N to get higher data throughput. This also lowers radio
interference and traffic.
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames
along with their 802.11n headers and wraps them in a 802.11n MAC
header. This method is useful for increasing bandwidth throughput in
environments that are prone to high error rates.
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames
without any of their 802.11n headers and wraps the header-less payload
in a single 802.11n MAC header. This method is useful for increasing
bandwidth throughput. It is also more efficient than A-MPDU except in
environments that are prone to high error rates.
Select Enable to use Short GI (Guard Interval). The guard interval is the
gap introduced between data transmission from users in order to reduce
interference. Reducing the GI increases data transfer rates but also
increases interference. Increasing the GI reduces data transfer rates but
also reduces interference.
A Basic Service Set (BSS) exists when all communications between
wireless clients or between a wireless client and a wired network client
go through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When
Intra-BSS is enabled, wireless client A and B can access the wired
network and communicate with each other. When Intra-BSS is disabled,
wireless client A and B can still access the wired network but cannot
communicate with each other.
This field is available only when the NBG-416N is in universal repeater
mode.
Select Enabled to have the NBG-416N copy the SSID and wireless
security settings of the associated AP, and use them for wireless
connections between the NBG-416N and its wireless clients.
Otherwise, select Disabled to configure different wireless and security
settings for wireless connections between the NBG-416N and its wireless
clients.
Click Apply to save your changes to the NBG-416N.
Click Reset to reload the previous configuration for this screen.
