The Adapter Settings screen controls and displays the device properties for the WiFi adapter installed on a computer. The WiFi adapter may be any one of the following:
To configure Adapter Settings:
Following are descriptions of the WiFi adapter settings.
| 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. 20MHz is the default setting. Use 20MHz if 802.11n channels are restricted. NOTE: This setting is available only if the WiFi adapter is one of the following:
|
802.11n Channel Width (5.2 GHz) |
Set high throughput channel width to maximize performance. Set the channel width to Auto or 20MHz. Auto is the default setting. Use 20MHz if 802.11n channels are restricted. NOTE: This setting is available only if the WiFi adapter is one of the following:
|
802.11n Mode |
The 802.11n standard builds upon 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. NOTE: This setting is available only if the WiFi adapter is one of the following:
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. |
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 allowed operating channel from the list.
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.
NOTE: This feature is only installed through an Administrator Package when a user's computer has one of the following WiFi adapters:
|
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 network 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.
NOTE: This feature is only installed through an Administrator Package when a user's computer has one of the following WiFi adapters:
|
HD Mode |
In a wireless WiFi environment where several access points are nearby, this feature will reduce interference and improve your wireless connection. The default setting is for this to be turned off (disabled). NOTE: This setting is available only if the WiFi adapter is one of the following:
|
Mixed Mode Protection |
Use to avoid data collisions in a mixed 802.11b/11g/11a/11n environment. Request to Send/Clear to Send (RTS/CTS) should be used in an environment where clients may not hear each other. CTS-to-self can be used to gain more throughput in an environment where clients are in close proximity and can hear each other. (CTS-to-self is not supported for 802.11n.) |
Power Management |
When creating an administrator package, Power Management lets you select a balance between power consumption and WiFi adapter performance.
Select one of the Power Saving Mode levels:
NOTE: Power consumption savings vary based on infrastructure settings. |
Preamble Mode |
Changes the preamble length setting received by the access point during an initial connection. Always use Auto Tx Preamble to provide optimal network throughput. Auto Tx Preamble allows automatic preamble detection. If supported, short preamble should be used. If not, use Long Tx Preamble. NOTE: This setting is only available if the client WiFi adapter is an Intel(R) PRO/Wireless 2915ABG Network Connection or an Intel(R) PRO/Wireless 2200BG Network Connection. |
Roaming Aggressiveness |
This setting lets you define how aggressively a wireless client roams to improve connection to an access point. Click Use default value to balance between not roaming and performance or select a value from the list.
|
Throughput Enhancement |
Changes the value of the Packet Burst Control.
|
If you decrease the transmit power, you reduce the WiFi radio coverage. Default Setting: Highest power setting Values:
If you select No change, then this setting will not be changed at the user's computer. NOTE: The optimal setting is for a user to always set the transmit power at the lowest possible level still compatible with the quality of their communication. This allows the maximum number of wireless devices to operate in dense areas and reduce interference with other devices that this radio shares radio spectrum with. NOTE: This setting takes effect when either Network (Infrastructure) or Device to Device (ad hoc) mode is used. |

Select which mode to use for connection to a WiFi network:
NOTE: These wireless modes (Modulation types) determine the discovered access points displayed in the WiFi Networks list. |
