WiFi Adapter Settings Description
Name Description
802.11n
Channel Width
(2.4 GHz)
Set high throughput channel width to maximize performance. Set the channel width to Auto or
20MHz. Use 20MHz if 802.11n channels are restricted.This setting applies to 802.11n capable
adapters only.
NOTE: This setting is does not apply to the following adapters:
Intel® Wireless WiFi Link 4965AGN (uses 20 MHz channel width only)
802.11n
Channel Width
(5.2 GHz)
Set high throughput channel width to maximize performance. Set the channel width to Auto or
20MHz. Use 20MHz if 802.11n channels are restricted. This setting applies to 802.11n capable
adapters only.
NOTE: This setting is does not apply to the following adapters:
Intel® Centrino® Wireless-N 1000
Intel® Wireless WiFi Link 4965AGN
802.11n Mode The 802.11n standard builds on previous 802.11 standards by adding multiple-input multiple-
output (MIMO). MIMO increases data throughput to improve transfer rate. Select Enabled or
Disabled to set the 802.11n mode of the WiFi adapter. Enabled is the default setting. This
setting applies to 802.11n capable adapters only.
NOTE: To achieve transfer rates greater than 54 Mbps on 802.11n connections, WPA2*-AES
security must be selected. No security (None) can be selected to enable network setup and
troubleshooting.
An administrator can enable or disable support for high throughput mode to reduce power-
consumption or conflicts with other bands or compatibility issues.
Ad Hoc
Channel
Unless the other computers in the ad hoc network use a different channel from the default
channel, there is no need to change the channel.
Value: Select the permitted operating channel from the list.
802.11b/g: Select this option when 802.11b and 802.11g (2.4 GHz) ad hoc band
frequency is used.
802.11a: Select this option when 802.11a (5 GHz) ad hoc band frequency is used. This
setting is does not apply to the Intel® Centrino® Wireless-N 1000 adapter.
NOTE: When an 802.11a channel is not displayed, initiating ad hoc networks is not supported
for 802.11a channels.
Ad Hoc Power
Management
Set power saving features for device to device (ad hoc) networks.
Disable: Select when connecting to ad hoc networks that contain stations that do not
support ad hoc power management
Maximum Power Savings: Select to optimize battery life.
Noisy Environment: Select to optimize performance or connecting with multiple clients.
Ad Hoc QoS
Mode
Quality of Service (QoS) control in ad hoc networks. QoS provides prioritization of traffic from
the access point over a wireless LAN based on traffic classification. WMM (Wi-Fi Multimedia) is
the QoS certification of the Wi-Fi Alliance (WFA). When WMM is enabled, the WiFi adapter uses
WMM to support priority tagging and queuing capabilities for Wi-Fi networks.
WMM Enabled (Default)
WMM Disabled
Fat Channel
Intolerant
This setting communicates to surrounding networks that this WiFi adapter is not tolerant of
40MHz channels in the 2.4GHz band. The default setting is for this to be turned off (disabled),
