the use of a site survey tool. If you want to increase wireless network security, you can disable the transmission of the beacon packets.
Click No to allow transmission of beacon packets from the access point.
Click Yes to disable the transmission of beacon packets from the access point.
Mode
The setting allows the user to select the 802.11 mode that the Dell Wireless 4350 Small Network Access Point will use when
communicating with wireless clients.
Select 802.11b and 802.11g if the access point is to support both 802.11g and 802.11b compatible wireless clients (default setting).
Select 802.11b if the access point is to support only 802.11b compatible wireless clients.
Select 802.11g if the access point is to support only 802.11g compatible wireless clients.
Network Name(SSID)
This setting allows the user to change the Network Name (SSID) of the Dell Wireless 4350 Small Network Access Point. The Service Set
Identifier (SSID) is a 32-character name that uniquely identifies all the computers and equipment that make up the wireless network. The
default value is “wireless”.
Transfer Rate
This setting allows the user to set the wireless throughput rate from the Dell Wireless 4350 Small Network Access Point to the wireless
clients. The transfer rate can be set to automatic or some other fixed value. It is recommended that you set the transfer rate to automatic
(Auto) to allow the wireless network devices to transmit at a rate they deem optimum.
Channel
This setting allows the user to set the radio channel that the Dell Wireless 4350 Small Network Access Point will operate on. The range
of available radio channels depends on the regulatory domain (e.g. 11 channels for U.S. and Canada & 13 channels for Europe). It is
recommended that you set the channel setting to Auto to allow the access point to locate the most suitable radio channel for operation.
Transmit Power Level
This setting allows the user to select the transmit radio power level of the Dell Wireless 4350 Small Network Access Point. The access
point supports five different transmit power levels and these are 8 dBm, 11 dBm, 14 dBm, 17 dBm and 20 dBm.
Advanced Options
This setting allows the user to configure specific radio transmission parameters for the Dell Wireless 4350 Small Network Access Point.
NOTE:If you want to configure the settings of Beacon Interval, RTS Threshold, Fragmentation Threshold, DTIM Interval and CTS
Protection, ensure that Advanced Options is selected first.
Beacon Interval
The Beacon Interval is the amount of time in Kusecs (one Kusec equals 1,024 microseconds) between radio beacons from the Dell
Wireless 4350 Small Network Access Point to its client stations. The available range is from 1 to 65535, with the default value being 100.
RTS Threshold
The RTS Threshold is the maximum packet size that the Dell Wireless 4350 Small Network Access Point will transmit without prior
transmission of a RTS (Request To Send) signalling packet. The available range is from 1 to 2346, with the default value being 2346.
The RTS (Request to Send) mechanism prevents the Hidden Node problem. A hidden node occurs when two stations are within range
of the same Access Point (AP) but are not within range of each other, they are “hidden” from each other. The packets from these two
stations may collide if they arrive at the AP at the same time. To prevent data collision with the hidden node, you can activate the RTS
mechanism. If the RTS mechanism is activated, the station will send a RTS first to inform the AP that it is going to transmit the data.
Then, the AP will reply with a CTS (Clear to Send) to all stations within its range to notify all other stations and reserve the bandwidth
for your data.
The RTS threshold controls what size data packet will cause an RTS to be transmitted. Only when the packet exceeds the RTS
threshold will the device send a RTS before sending the packet. There is a trade-off to consider when choosing a value for the RTS
threshold. Low values will cause the RTS to be sent more often which would waste the bandwidth. However, the more often RTS packets
are sent, the quicker the system can recover from data collisions. It is recommended to use the default value or only minor reductions of
this default value.
Fragmentation Threshold
