2. Click Show advanced options. The advanced options are displayed.
3. Click the Radio tab.
4. Under the channel 2.4.GHz or 5 GHz, or both, configure the following parameters.
Parameter Description
Legacy only
Select Enabled to run the radio in non-802.11n mode. This option is set to Disabled by
default.
802.11d / 802.11h
Select Enabled to allow the radio to advertise its 802.11d (Country Information) and
802.11h (Transmit Power Control) capabilities. This option is set to Disabled by default.
Beacon interval
Enter the Beacon period for the W-IAP in milliseconds. This indicates how often the 802.11
beacon management frames are transmitted by the access point. You can specify a value
within the range of 60-500. The default value is 100 milliseconds.
Interference
immunity level
Select to increase the immunity level to improve performance in high-interference
environments.
The default immunity level is 2.
l Level 0—no ANI adaptation.
l Level 1—Noise immunity only. This level enables power-based packet detection by
controlling the amount of power increase that makes a radio aware that it has received a
packet.
l Level 2—Noise and spur immunity. This level also controls the detection of OFDM
packets, and is the default setting for the Noise Immunity feature.
l Level 3—Level 2 settings and weak OFDM immunity. This level minimizes false detects
on the radio due to interference, but may also reduce radio sensitivity. This level is
recommended for environments with a high-level of interference related to 2.4 GHz
appliances such as cordless phones.
l Level 4—Level 3 settings, and FIR immunity. At this level, the W-IAP adjusts its sensitivity
to in-band power, which can improve performance in environments with high and
constant levels of noise interference.
l Level 5—The W-IAP completely disables PHY error reporting, improving performance by
eliminating the time the W-IAP would spend on PHY processing.
NOTE: Increasing the immunity level makes the W-IAP to lose a small amount of range.
Channel switch
announcement
count.
Specify the count to indicate the number of channel switching announcements that must be
sent before switching to a new channel. This allows associated clients to recover gracefully
from a channel change.
