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
The fragmentation threshold determines the size of data packets that will be fragmented
before transmission. The available range is from 1 to 2346, with the default value being 2346
(Note: The fragmentation threshold is specified in bytes).
Data packets that are smaller than the specified fragmentation threshold value will not be
fragmented. Data packets that are larger than the fragmentation threshold will be fragmented
into smaller packets and transmitted one at a time instead of all at once. The purpose of
fragmentation is to reduce the need for retransmission and improve overall network
performance. Fragmentation is normally activated when there is heavy traffic on the wireless
network or the network is operating in a high interference environment. It is recommended to
use the default value or only minor reductions of this default value.
DTIM Interval
The DTIM (Delivery Traffic Indication Message) Interval setting determines how often a
beacon contains a traffic indicator map (TIM). The TIM is used to alert stations in sleep mode
that date is available for reception. The DTIM Interval is always a multiple of the beacon period
and the available range is from 1 to 255, with the default value being 1.
CTS Protection mode
The CTS Protection mechanism allows interoperability of 802.11b & 802.11g devices in the
same location. When the CTS Protection mechanism is enabled, 802.11g devices will inform
802.11b devices (using either a CTS/RTS or CTS-Self broadcast message) whenever a
802.11g data transmission is to occur. Enabling CTS Protection will reduce the throughput
performance of your access point.
The options available for CTS Protection mode are none, always and auto (with the default
being auto). In Auto mode, the Dell Wireless 4350 Small Network Access Point will only enable
CTS Protection if any 802.11b devices exist within it’s wireless range. If the mode is set to
none, CTS Protection is disabled. If the mode is set to always, the CTS protection mode is
always on.
The options available for CTS Protection Type are CTS/RTS and CTS-Self (with the default
being CTS-Self). The CTS/RTS mechanism results in a lower throughput performance than
the CTS-Self mechanism.
Wireless Repeater
The Wireless Repeater setting can be used to increase the coverage of your wireless network.
You need two or more Dell Wireless 4350 Small Network Access Point to set up wireless
repeating. The access point that is connected to the network is known as the “root AP”, the
access points that extend the coverage of this root AP are known as “repeater AP’s”.
Wireless Repeater Link
To Configure your Access Point as a Wireless Repeater:
1.
Click the option Enable this AP as a Wireless Repeater.
2.
Type the wireless network name (SSID) of the root AP in the SSID of root AP field.
3.
Set the “Network Encryption” mode as None, If the root AP does not provide wireless
security.
4.
Set
the “Network Encryption” mode as WEP, If the wireless security mode of the root AP is
WEP. Then, set the proper key value, key length, key format, and default key.
5.
Click the Submit button.
The repeater AP must be located within the coverage of your root AP in order to associate with
the root AP and extend it's coverage. The repeater AP should not be connected into the wired
network.
NOTE: Ensure all Dell Wireless 4350 Small Network Access Points are set to same
wireless settings.

Rogue AP Detection
The Rogue AP Detection feature is an advanced feature that is used by network administrators
to scan for adjacent access points. A table of detected access points is presented to the
administrator and a determination if any rogue access points are present on the network can be
made by verifying the SSID and MAC addresses.
Rogue AP Detection
There are three modes of operation for Rogue AP detection (a) Background scan (always-on),
(b) Background scan (scheduled) & (c) Foreground scan.
When the background scan is enabled, the access point will periodically scan the wireless
channels (a single channel at a time for 400 ms) if and only if certain load conditions are met.
Any wireless stations that are associated to the AP may experience a loss of the AP during the
scan interval. The background scan can either be running continuously or scheduled to run
during specific periods. If scheduled, the background scan should run during periods of
inactivity (e.g. during the night or at weekends).
When a foreground scan occurs, the AP will immediately reset and upon reboot will scan all
the available wireless channels for an extended period. A foreground scan will cause
immediate termination of all and any wireless clients.
Enable Rogue AP Detection - Background Scan (always-on):
To enable the background scan (always-on) mode of Rogue AP detection, perform the
following steps:
1.
Click to select Enable Rogue AP Detection (Always-On).
2.

1. Click to select Enable Rogue AP Detection (Always-On).
2. Click the Scan Now button.
NOTE: Any wireless stations that are associated to the Dell Wireless 4350 Small Network
Access Point will loss connection to the access point during the scan interval.
The Rogue AP detection parameters can be varied from their default values. The default values
are (a) Rogue AP Detection Scan Interval = 1 minute. (b) Table Entry Removal of Absent
Access Points = 1440 minutes (i.e. 24 hours). The Rogue AP Detection Scan Interval
parameter determines how often a background scan may be performed by the access point.
The Table Entry Removal of Absent Access Points parameter determines how long an entry will
appear in the table before it is removed.
To configure the Rogue AP Detection Parameters:
1.
Click to select Enable Rogue AP Detection (Always-On).
2.
Click to select Configure Rogue AP Detection Parameters.
