Network Setup
The optimal power level for the specified channel is best determined by a site survey prior to
installation. Available settings are determined according to the selected channel. Set a higher power
level to ensure RF coverage in WLAN environments that have more electromagnetic interference or
greater distances between the Access Point and MUs. Decrease the power level according to the
proximity of other Access Points. Overlapping RF coverage may cause lost packets and difficulty for
roaming devices trying to engage a Access Point. After setting a power level, channel and placement
the RF output power for the Access Point is displayed in mW. Default is 20 dBm for both 802.11bg
and 802.11a
NOTE
After setting a power level, channel and placement the RF output power for the Access Point is displayed below
in mW.

Use the drop-down menu to configure the Antenna Diversity settings for
Access Points using external antennas. Options include:
• Full Diversity
Primary Only -
•
Secondary Only
•
Antenna Diversity should only be enabled if the Access Point has two
matching external antennas. Default value is
Sets the maximum number of MUs that can associate to a radio.
The Adoption Preference ID defines the preference ID of the
controller.The value can be set between 1 and 65535. To make the
radios preferred, the Access Point preference ID should be same as
adoption preference ID.
The adoption preference id is used for AP load-balancing. A controller will
preferentially adopt Access Points which have the same adoption-
preference-id as the controller itself.

However, some devices (SpectraLink phones) require long preambles. This
checkbox does not display if using an 802.11a radio.
