Multiple SSID1~SSID3
The device supports 4 SSIDs.
Broadcast(SSID)
After initial State opening, the device broadcasts the SSID of the router to
wireless network
AP Isolation
If AP isolation is enabled, the clients of the AP cannot access each other
MBSSID AP Isolation
AP isolation among the devices which are not belong to this AP and along to,
when the option is enabled, the devices which do not belong to this AP cannot
access the devices which are within the AP.
BSSID
A group of wireless stations and a WLAN access point (AP) consists of a basic
access device (BSS), each computer in the BSS must be configured with the
same BSSID, that is, the wireless AP logo

compatibility, and security of the system
Channel Bandwidth
Select channel bandwidth, default is 20 MHz and 20/40 MHz.
Guard Interval
The default is automatic, in order to achieve good BER performance, you must
set the appropriate guard interval
Reverse Dirction Grant
(RDG)
Enabled: Devices on the WLAN are able to transmit to each other without
requiring an additional contention-based request to transfer (i.e. devices are
able to transmit to another device on the network during TXOP)
Disabled: Devices on the WLAN must make a request for transmit when
communicating with another device on the network
STBC
Space-time Block Code
Enabled: Multiple copies of signals are transmitted to increase the chance of
successful delivery
Disabled: STBC is not employed for signal transmission
Aggregation MSDU (A-
MSDU)
Enabled: Allows the device to aggregate multiple Ethernet frames into a single
802.11n, thereby improving the ratio of frame data to frame overhead
Disabled: No frame aggregation is employed at the router
