Managing SonicPoints in Managed Mode
Antenna Diversity
: The
Antenna Diversity
setting determines which antenna the SonicPoint
uses to send and receive data. You can select
à
Best
: This is the default setting. When
Best
is selected, the SonicPoint automatically
selects the antenna with the strongest, clearest signal. In most cases,
Best
is the optimal
setting.
à
1
: Select
1
to restrict the SonicPoint to use antenna 1 only. Facing the rear of the
SonicPoint, antenna 1 is on the left, closest to the power supply.
à
2
: Select
2
to restrict the SonicPoint to use antenna 2 only. Facing the rear of the
SonicPoint, antenna 2 is on the right, closest to the console port.
Beacon Interval (milliseconds)
: Enter the number of milliseconds between sending out a
wireless beacon.
DTIM
Interval
: Enter the interval in milliseconds.
Fragmentation Threshold (bytes)
: Enter the number of bytes of fragmented data you want
the network to allow.
RTS Threshold (bytes)
: Enter the number of bytes.
Maximum Client Associations
: Enter the maximum number of clients you want the
SonicPoint to support on this radio at one time.
Preamble Length
: (802.11g Adv) Establishes the style of the preamble which indicates the
starting point and ending point of the frame. The preamble can be Long or Short. The Short
type helps optimize performance. The default value is Long.
CCK OFDM Power Delta
: (802.11g Adv) Enables you to control the power difference between
a SonicPoint g and b client. CCK indicates greater power and OFDM indicates lesser power.
You can specify three values for this field: 0 dBm, 1 dBm, and 2 dBm.
Protections Fields:
These settings are appropriate when you allow both the SonicPoint b and
g clients to be present at the same time. Since g clients transmit at a high rate, the b clients
(that operate at a slower rate) cannot understand the traffic sent by a g client. It creates the
problem of the b client not knowing when the media is clear to send traffic. You select a
protection method is to solve this issue. The g clients need to send CTS or CTS-RTS traffic at a
slow rate (1 Mbps, 2 Mbps up to 11 Mbps) so that b clients can understand the traffic. The three
protection methods are:
à
Protection Mode
: (802.11g Adv).
à
Protection Rate
: (802.11g Adv).
à
Protection Type
: (802.11g Adv).
Enable Short Slot Time
: (802.11g Adv) Enables short slot burst performance to address
delays required in the MAC layer for radio transmission.
Allow Only 802.11g Clients to Connect
: (802.11g Adv) Enables only the SonicPoint G clients
to connect to the network.

Configure the settings in the
802.11g Radio
and
802.11g Advanced
tabs. These settings affect
the operation of the 802.11g radio bands. The SonicPoint has two separate radios built in.
Therefore, it can send and receive on both the 802.11a and 802.11g bands at the same time.
The settings in the
802.11g Radio
and
802.11g Advanced
tabs are similar to the settings in the
802.11a Radio
and
802.11a Advanced
tabs. Follow the instructions in step 3 and step 4 in this
procedure to configure the 802.11g radio.
When a SonicPoint unit is first connected and powered up, it will have a factory default configuration
(IP Address 192.168.1.20, username: admin, password: password). Upon initializing, it will attempt to
find a SonicOS device with which to peer. If it is unable to find a peer SonicOS device, it will enter into
a Stand-Alone Mode of operation with a separate stand-alone configuration allowing it to operate as a
standard Access Point.
