supported BSS, with each BSS using the same beacon interval. The beacon interval
can be configured between 40 and 3500 ms.
DTIM：Default setting is 1. DTIM Interval, always a multiple of the beacon period,
determines how often the beacon contains a traffic indicator map (TIM). The TIM
alerts clients in sleep state to stay awake long enough to receive their data frames.
The value range is from 1 to 255.
Fragmentation Threshold：Default setting is 2346 bytes. The fragmentation threshold,
specified in bytes, determines whether data packets will be fragmented and at what
size. Frames that are smaller than the specified fragmentation threshold value will not
be fragmented. Frames that are larger than the fragmentation threshold will be
fragmented into smaller packets and transmitted a piece at a time instead of all at
once. The setting must be within the range of 256 to 2346 bytes. It is recommended
to use the default value or only minor reductions of this default value.
Protection Mode：Default setting is "None". If set to "CTS-Only" then when protection is
turned on and prior to the transmission of an 802.11g frame, the AP sends out a CTS
frame (also known as CTS-to-Self) to set the NAV in all the clients so that they will not
transmit during the time period of the subsequent data packet from the AP. If set to
"RTS-CTS" then the AP sends a RTS frame, waits for the clients CTS frame and then
sends the data packet. Setting "RTS-CTS" will allow more robust operation, but at the
expense of additional overheads.
Protection Rate: The
RTS/CTS Threshold：If a frame is smaller than the RTS/CTS threshold, it will be sent by
the AP without modification. If a frame is larger than the RTS/CTS threshold, then two
frames will be sent by the AP. The first frame is an RTS (request to send) frame. After
the RTS frame is sent, the AP listens for the corresponding CTS from the target client.
Upon reception of the CTS, the AP then sends the data frame. There are trade-offs
when considering what value you should set for the RTS/CTS threshold. Smaller values
will cause RTS to be sent more often, increasing overheads. However, the more often
RTS packets are sent, the sooner the system can recover from collisions. It is
recommended to use the default value or only minor reductions of this default value.
The value range is from 0 to 2347.
Distance：Target area distance.
IGMP Snooping：AP is a Layer 2 device when it is configured as Switch mode.
However, IGMP Snooping implementation on AP is a little bit different than that of
standard Layer 2 Switch.
Each Virtual AP (VAP) port is similar to a Layer 2 switch port. With IGMP Snooping
enabled in the AP, clients associated to a VAP will only receive multicast packets if
there is at least one client joined the multicast group in that VAP. Unlike ordinary IGMP
Snooping implementation, where Layer 2 switch converts multicast to unicast and
delivers them to devices registered with the multicast group, AP should simply send
