Fragment Threshold: Enter a value between 256 and 2346. The default value is 2346. Packet
size larger than this threshold, will be fragmented (sent with several pieces instead of one chunk)
before transmission. A smaller value results in smaller frames but allows a larger number of
frames in transmission. A lower Fragment Threshold setting can be useful in areas where
communication is poor or disturbed by a serious amount of radio interference.
Broadcast SSID: The administrator has the option of enabling or disabling the SSID for VAP1
which is the Private Zone. Default value is set at Disable where users will not be able to scan for
the SSID.
Station Isolation: By enabling this function, all stations wirelessly associated to this zone are
isolated from one another and can only communicate with the system.
WMM: The default is Enable. Wi-Fi Multimedia (WMM) is a Quality of Service (QoS) feature that
prioritizes wireless data packets based on four access categories: voice, video, best effort, and
background. Applications without WMM and applications that do not require QoS are assigned to
the best-effort category, which receives a lower priority than that of voice and video. Therefore,
WMM decides which data streams are more important and assigns them a higher traffic priority.
This option works with WMM-capable clients only.
IGMP Snooping: IGMP is a multicast constraining mechanism which may flood the broadcast
domain. This is effective for dense internet usage such as conventions or campuses.
Normally, we use VAP2, the VAP under Public Zone, to provide wireless service to public clients in a hotspot
environment. Service Zones 2 and 3 may be enabled to support VAP3 and VAP4. To configure the Public Zones'
Wireless Settings, go to: System >> Service Zones, click Configure for each respective zone.
