useful in areas where many client devices are associating with the gateway or in areas where the clients are far apart
and can detect only the gateway but not each other. The default value is set at 2346.
Fragment Threshold: Enter a value between 256 and 2346. The default value is 2346. A 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.
The default value is set to 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 gateway.
WMM: 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.
VAP2 is configured under the Public Zone to provide wireless service to public clients in a hotspot environment. To configure Public
Zone's Wireless Settings, click on Main Menu then System and then Service Zones. Click Configure for the Public zone.
Wireless Settings: VAP2 (Wireless Settings for Public Zone)
Basic: Enable the VAP Status if you wish to provide a wireless service under this zone. Assign an ESSID to VAP2 under
Public Zone or use the default. The ESSID of the Public Zone is broadcasted so that public users can perform a scan
for this network.
Security: Configure the wireless network under Public Zone with security encryption to prevent unauthorised wireless
association if necessary. The supported encryption standards are WEP and WPA-PSK.
WEP:
802.11 Authentication: Select from Open System or Shared Key.
WEP Key Length: Select from 64-bit, 128-bit, 152-bit key length.
WEP Key Format: Select from ASCII or Hex format for the WEP key.
WEP Key Index: Select a key index from 1~4. The WEP key index is a number that specifies which WEP key
will be used for the encryption of wireless frames during data transmission.
WEP Keys: Provide the pre-defined WEP key value; the system supports up to 4 sets of WEP keys.
WPA-PSK:
Cipher Suite: Select an encryption method from TKIP (WPA), AES (WAP2), or Mixed.
Pre-shared Key / Pass-phrase: Enter the key value for the pre-shared key or pass-phrase.
Group Key Update Period: The time interval for the Group Key to be renewed; the time unit is in seconds.
Advanced: The parameters in Advanced are wireless settings that allow customization of data transmission, enhanced
security and wireless roaming.
