Performing Advanced Configuration
•
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, and Australia
— ETSI - Most of Europe, including the United Kingdom, Ireland, Singapore, and Hong Kong
— TELEC: Japan
— IL - Israel
•
Network Name (SSID): Enter a Network Name (between 1 and 32 characters long) for the wireless network. You
must configure each wireless client to use this name as well.
•
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
Wireless Distribution System (WDS), it must be disabled. See
information.
•
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 a WDS). Available Channels vary based on regulatory domain. See
Channel
Frequencies.
•
Distance Between APs: Set to Large, Medium, Small, Microcell, or Minicell depending on the site survey for
your system. By default, this parameter is set to Large. The distance value is related to the Multicast Rate
(described next). In general, a larger distance between APs means that your clients operate a slower data rates
(on average). This feature is available only if you are using an Orinoco Classic Gold card. See
APs
for more information.
•
Multicast Rate: Sets the rate at which Multicast messages are sent. This value is related to the Distance Between
APs parameter (described previously). The table below displays the possible Multicast Rates based on the
Distance between APs setting. By default, this parameter is set to 2 Mbits/sec. This feature is available only if you
are using an Orinoco Classic Gold card. See

•
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
•
Interference Robustness: Enable this option if other electrical devices in the 2.4 GHz frequency band (such as a
microwave oven or a cordless phone) may be interfering with the wireless signal. The AP will automatically
fragment large packets into multiple smaller packets when interference is detected to increase the likelihood that
the messages will be received in the presence of interference. The receiving radio reassembles the original packet
once all fragments have been received. This feature is available only if you are using an Orinoco Classic Gold
card. This option is disabled by default.
•
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. See
•
Wireless Service Status: Select shutdown to shutdown the wireless service on a wireless interface, or resume
to resume wireless service. See
•
Load Balancing: Enable this option so clients can evaluate which Access Point to associate with, based on
current AP loads. This feature is enabled by default; it helps distribute the wireless load between APs. This feature
is not available if you are using an ORiNOCO ComboCard or a non-ORiNOCO client with the AP.
