DIR-882 AC2600 Wave 2 MU-MIMO Wi-Fi Gigabit Router with
3G/LTE Support and 2 USB Ports
User Manual
Configuring via Web-based Interface
Parameter Description
Enable DFS
Available on the 5 GHz tab.
Move the switch to the right to enable the DFS (Dynamic Frequency
Selection) mechanism. Upon that the router uses the channels at
which radars and other mobile or stationary radio systems can
operate, but switches to other channels if these devices require this.
In order to use the DFS mechanism, the automatic channel selection
should be enabled (on the Wi-Fi / Basic Settings page).
Move the switch to the left not to let the router use the channels at
which radars and other mobile or stationary radio systems can
operate.
Drop multicast
Move the switch to the right to disable multicasting for the router's
WLAN. Move the switch to the left to enable multicasting from the
WAN connection selected on the Advanced / IGMP/MLD page. If
the switch is moved to the right, the device will not be available by
the domain name for Wi-Fi clients.
Enable TX
Beamforming
TX Beamforming is the signal processing/directing technique which
helps to support a high enough transfer rate in the areas with difficult
conditions for the signal propagation.
Move the switch to the right to improve the signal quality.
STBC
The STBC (Space-time block coding) technique allows increasing
data transfer reliability even for portable devices equipped with poor
antennas (smartphones, pads, etc.) due to using several data streams
and processing several versions or received data.
Move the switch to the right if you need to use the STBC technique.
Enable 802.11k
802.11k standard allows faster roaming of clients between access
points within the same network. Clients supporting 802.11k standard
can request a list of neighbor access points with their signal levels
and Wi-Fi channel numbers. The device does not need to probe all of
the available channels, but selects an access point to roam to from
the list.
Move the switch to the right if you need to use 802.11k standard.
