Regulatory Domain: Reports the regulatory domain for which the AP is certified. Not all features or channels are
available in all countries. The available regulatory domains include:
—
FCC - U.S., Canada, Mexico, Argentina, Australia
—
ETSI - European Union, Brazil, India, Saudi Arabia, United Arab Emirates
—
TELEC: Japan
—
SG: Singapore
—
ASIA: China, Hong Kong, South Korea

TW: Taiwan
•
Primary Network Name (SSID): Enter a Network Name (between 2 and 32 characters long) for the primary
wireless network. You must configure each wireless client using this network to use this name as well. Additional
SSIDs and VLANs may be configured under Configure > SSID/VLAN/Security. Up to 16 SSID/VLAN pairs may
be configured per wireless interface.
•
Auto Channel Select: The AP scans the area for other Access Points and selects a free or relatively unused
communication channel. This helps prevent interference problems and increases network performance. By default
this feature is enabled; see
802.11g Channel Frequencies
for a list of Channels.
•
Frequency Channel: When Auto Channel Select is enabled, this field is read-only and displays the Access Point’s
current operating channel. When Auto Channel Select is disabled, you can specify the Access Point’s operating
channel. If you decide to manually set the unit’s channel, ensure that nearby devices do not use the same
frequency (unless you are setting up WDS links). Available Channels vary based on regulatory domain. See
802.11g Channel Frequencies
.
•
Transmit Rate: Select a specific transmit rate for the AP. The values available depend on the Operational Mode.
Auto Fallback is the default setting; it allows the AP to select the best transmit rate based on the cell size.
—
For 802.11b only -- Auto Fallback, 1, 2, 5.5, 11 Mbits/s. Auto Fallback is the default setting; it allows the
AP unit to select the best transmit rate based on the cell size.
—
For 802.11g only -- Auto Fallback, 6, 9, 12, 18, 24, 36, 48, 54 Mbits/s
—
For 802.11b/g -- Auto Fallback, 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbits/s
—
For 802.11a only -- Auto Fallback, 6, 9, 12, 18, 24, 36, 48, 54 Mbits/s.
•
DTIM Period: The Deferred Traffic Indicator Map (DTIM) is used with clients that have power management
enabled. DTIM should be left at 1, the default value, if any clients have power management enabled. This
parameter supports a range between 1 and 255.
•
RTS/CTS Medium Reservation: This parameter affects message flow control and should not be changed under
normal circumstances. Range is 0 to 2347. When set to a value between 0 and 2347, the Access Point uses the
RTS/CTS mechanism for packets that are the specified size or greater. When set to 2347 (the default setting),
RTS/CTS is disabled. See RTS/CTS Medium Reservation for more information.
•
Closed System: Check this box to allow only clients configured with the Access Point’s specific Network Name to
associate with the Access Point. When enabled, a client configured with the Network Name "ANY” cannot connect
to the AP. This option is disabled by default.
•
Wireless Service Status: Select shutdown to shutdown the wireless service on a wireless interface, or resume to
resume wireless service. See
Wireless Service Status
for more information.
