• Disabled

Notes

The settings are only available for the adapters: Intel® WiMAX/WiFi Link 5350 Intel® WiMAX/WiFi Link 5150 Intel® WiFi Link 5300 Intel® WiFi Link 5100 Intel® Wireless WiFi Link 4965AGN For other newer adapters, HT Mode or 802.11n/ac Wireless Mode replaces this setting. To achieve transfer rates greater than 54 Mbps on 802.11n connections, you must select WPA2-AES security. You can select no security (None) 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.

Channel width or 802.11n Channel width(band 2.4/5GHz)

Use channel width to set high throughput mode channel width in order to maximize performance.

• Auto (default): For band 5GHz, this setting uses 20/40/80/160 MHz depending on the wireless access point or router
• 20 MHz

Ad-hoc channel 802.11 b/g

Ad-hoc channel 802.11 b/g is the band and channel selection for device to device (ad-hoc) networks. You don't need to change the channel unless the other computers in the ad-hoc network are not using the default channel.

If you must change the channel, select the allowed operating channel:

• 802.11b/g (default): Select when using 802.11b and 802.11g (2.4 GHz) ad-hoc band frequency.
• 802.11a: Select when using 802.11a (5 GHz) ad-hoc band frequency.

Note	This setting isn't available on Windows® 10

Ad-hoc power management

Set power-saving features for device to device (ad-hoc) networks.

• Disabled: Select when connecting to ad-hoc networks with stations that don't support ad-hoc power management.
• Maximum Power Savings: Select to optimize battery life.
• Noisy Environment: Select when connecting in a noisy environment to prevent performance degradation.

Note	This setting isn't available on Windows® 10These settings are only available for the adapters: Intel® WiMAX/WiFi Link 5350 Intel® WiMAX/WiFi Link 5150 Intel® WiFi Link 5300 Intel® WiFi Link 5100 Intel® Wireless WiFi Link 4965AGN

Ad-hoc QoS mode

The Quality of Service (QoS) control in ad-hoc networks prioritizes traffic from the access point over a Wi-Fi Local Area Network (LAN) based on traffic classification. Wi-Fi Multimedia* (WMM*) is the QoS certification of the Wi-Fi Alliance* (WFA). When WMM is enabled, the adapter uses WMM to support priority tagging and queuing capabilities for Wi-Fi networks.

• WMM Enabled
• WMM Disabled (default)

Note	This setting isn't available on Windows® 10.The feature isn't installed through an Administrator Package when your computer has either an: Intel® PRO/Wireless 2915ABG Network Connection Intel® PRO/Wireless 2200BG Network Connection

ARP offloading for WoWLAN

ARP offload is the network adapter's ability to respond to an IPv4 ARP request without waking the computer. To enable the feature, both the hardware and the driver must support ARP offload.

• Enabled (default)
• Disabled

Bluetooth® AMP

Enable or disable Bluetooth® AMP.Alternate MAC/PHY (AMP) uses the 802.11(Wi-Fi) as the high-speed transport. If disabled, Bluetooth HS is turned off.

• Enabled
• Disabled (default)

Fat channel intolerant

The setting communicates to surrounding networks that the Wi-Fi adapter isn't tolerant of 40 MHz channels in the 2.4 GHz band. When disabled the adapter doesn't send this notification.

• Enabled
• Disabled (default)

GTK rekeying for WoWLAN

Group Temporal Key (GTK) Rekey is used to encrypt and decrypt network traffic.

• Enabled (default)
• Disabled

MIMO power save mode

MIMO power save mode, also known as spatial multiplexing power save (SMPS) mode, allows the client to save power by keeping one antenna in a receive idle state.

• Auto SMPS (default): The client decides automatically what SMPS mode to apply depends on different conditions.
• Dynamic SMPS: The client keeps only one antenna active. The access point (AP) must send request to send (RTS) packet to trigger the client to wake the sleeping radios/antenna before sending MIMO packets.
• Static SMPS: The client keeps only one antenna active and the AP cannot send MIMO packets to the client.
• No SMPS: The client always keeps all antennas active and the AP can send MIMO packets to the client.

Note	Some legacy APs may have compatibility issue with supporting the SMPS mode and may cause various link quality problems such as low throughput. Change this setting to No SMPS may help to work around the issue.

Mixed mode protection

Use mixed mode protection to avoid data collisions in a mixed 802.11b and 802.11g environment. Use Request to Send/Clear to Send (RTS/CTS) in an environment where clients may not hear each other. Use CTS-to-self to gain more throughput in an environment where clients are within hearing proximity.

• CTS-to-self Enabled
• RTS/CTS Enabled (default)

Note	The setting isn't valid when 802.11n mode is enabled.

NS offloading for WoWLAN

NS offload is the network adapter's ability to respond to a Neighbor Discovery Neighbor Solicitation request with a Neighbor Advertisement without waking the computer. Both the hardware and the driver must support NS offload to enable this feature.

• Enabled (default)
• Disabled

Packet Coalescing

Enables power saving by reducing the number of receive interrupts. The feature reduces receive interrupts by coalescing random broadcast or multicast packets.

• Enabled (default)
• Disabled

Preferred bandIn an environment with other radiating devices nearby (such as microwave ovens, cordless telephones, access points, or client devices), in order to reduce interference, you may prefer the 5GHz band over the 2.4GHz band, or the reverse.

• No Preference (default)
• Prefer 2.4 GHz band
• Prefer 5 GHz band

Roaming aggressiveness

This setting alters the signal strength threshold at which the WiFi adapter starts scanning for another candidate AP. The default value is Medium. Depending on the environment, one option may work better than the other. You may try other values to see which works best for your environment. However, it is recommended to revert back to the default (Medium) if no improvement is observed with other values.

• Lowest: The WiFi adapter will trigger scan a for another candidate AP when the signal strength with the current AP is very low.
• Medium-Low
• Medium (default): Recommended value.
• Medium-High
• Highest: The WiFi adapter will trigger scan a for another candidate AP when the signal strength with the current AP is still good.

Sleep on WoWLAN disconnect

Sleep on WoWLAN Disconnect is the ability to put the device to sleep/drop connection when WoWLAN is disconnected.

• Enabled
• Disabled (default)

Throughput Booster or Throughput Enhancement

Enhance the Transmit throughput by enabling packet bursting. When this setting is enabled and the client (Wi-Fi adapter) has buffered enough data, the client is able to hold longer possession of the air medium than it normally does to send the data to the Access Point (AP). This only improves the upload throughput (from client to the AP) and is mostly effective for usages like uploading large files or upstream benchmarks.

• Enabled
• Disabled (default)

Note	In a Wi-Fi network only one client can transmit at a time. So the throughput for other clients in the same network may be negatively impacted when this feature is enabled.

Note:

Transmit power

The optimal setting is to set the transmit power at the lowest possible level still compatible with communication quality. The setting allows the maximum number of wireless devices to operate in dense areas. It reduces interference with other devices that share the radio spectrum. If you decrease the transmit power, you reduce the radio coverage.

• Lowest: Sets the adapter to the lowest transmit power. Increase the number of coverage areas or confine a coverage area. You should reduce the coverage area in high traffic areas to improve overall transmission quality and avoid congestion or interference with other devices.
• Medium-low, Medium, or Medium-high: Set by country requirements.
• Highest (Default): Sets the transmit level of the adapter to a maximum. Use this setting in environments with limited radio devices for maximum performance and range.

Note	This setting takes effect when either Network (Infrastructure) or Device to Device (ad-hoc) mode is used.

U-APSD support

U-APSD (or WMM-Power Save or WMM-PS) is a Wi-Fi capability that saves power consumption on low periodic latency-sensitive traffic modes, like a VoIP. We have identified interoperability (IOT) issues with certain access points that result in reduced RX throughput.

• Enabled
• Disabled (default)

Wake on magic packet

If enabled, the setting wakes the computer from a sleep state when it receives a Magic Packet from a sending computer. The Magic Packet contains the MAC address of the intended destination computer. Enabling turns on Wake on Magic Packet. Disabling turns off Wake on Magic Packet. It only disables the Magic Packet feature, not Wake on Wireless LAN.

• Enabled (default)
• Disabled

Wake on pattern match

Wakes the computer from a sleep state when an adapter receives a particular wake pattern. Window 7*, Windows 8* and Windows® 10 support the feature. Patterns are typically:

• Wake on new incoming TCP connection for IPv4 and IPv6 (TCP SYN IPv4 and TCP SYN IPv6)
• Wake on 802.1x reauthentication packets

Disabling only disables the pattern match feature, not Wake on Wireless LAN.

• Enabled (default)
• Disabled
