Override Channel and Transmission Power in the Basic
Profile Group
The table on the Basic Wireless Settings screen shows the access points that are managed
in the profiles of the basic profile group and to which the channel allocation and basic RF
management settings apply.
After you have configured the wireless settings for the basic profile group (see the previous
section), you can change the channel, the transmission power, or both for individual access
points in the basic profile group.
For you to be able to configure these settings in the table, there are two requirements:
• Channel
. To enable the Access Point Channel menu in the table, you need to disable
automatic channel allocation on the Channel Allocation screen (see Configure Channels
on page 137).
• Transmission power.
To enable the Tx Power menu in the table, you need to disable
automatic Tx power control on the basic RF Management screen (see RF Management
for the Basic Profile Group on page 141).
 To override the channel and transmission power for individual access points in a
security profile of the basic profile group:
1. Select Configuration > Wireless > Basic > Wireless.
AMPDU
(802.11n only)
Select the On radio button to allow the aggregation of several MAC
frames into a single large frame to achieve higher throughput.
Enabling AMPDU can lead to better network performance. Select the
Off radio button to disable this option.
RIFS Transmission
(802.11n only)
Select the On radio button to enable the reduced interframe space
(RIFS) option to allow transmission of successive frames at dif
ferent
transmit powers.
Enabling RIFS can lead to better network performance. Select the
Off
radio button to disable this option.
DTIM Interval (1-255) Enter the delivery traffic indication message (DTIM) or the data beacon
rate that you want to use.
This sets the message period of the beacon delivery traffic indication in
multiples of beacon intervals.
Preamble Type
(802.11b/bg only)
Select one of the following radio buttons to specify the preamble type:
• Auto. Automatically
handles
both long and short preambles.
A short transmit preamble provides better performance. Auto is the
default setting.
• Long. Enables a long transmit preamble to provide a more reliable
connection or a slightly longer range.
