Introduction: Dell Wireless WLAN Card User Guide
Types of Wireless Networks
The two types of wireless networks are infrastructure networks and ad hoc networks. An infrastructure network is also referred to as an access point (AP) network, and an ad hoc networkis also referred to as a peer-to-peer network or a computer-to-computer network. The infrastructure type of network is the type most commonly used in both home and corporate environments.  Access point and ad hoc networks should be configured to use the non-overlapping channels 1, 6, 11 or channel 14 when outside of the United States for optimal performance for 802.11b or 802.11g networks. Channels 2, 3, 4, 5, 7, 8, 9, 10, 12, and 13 are overlapping channels and could reduce your performance due to interference.

Setting Advanced Properties
Disable Bands
The Disable Bands property will be changed to “None” for both fresh installations and upgrade installations with the installation of this driver package.
-------------------------------------------------------------------------------WMM
Wi-Fi Multimedia (WMM™). The WMM property enables quality of service for audio, video, and voice applications over a wireless network by prioritizing streams of content and optimizing the way the network allocates bandwidth among competing applications.
Auto (default). With WMM set to Auto, when the wireless client connects to the AP, and the AP has Unscheduled Automatic Power Save Delivery(UAPSD) enabled, the wireless client is allowed to enter Power Save mode. If the AP does not support UAPSD, the wireless client cannot enter Power Save mode. If this is the case, the battery in the client computer discharges more quickly and must be recharged more frequently.
Enabled. The wireless client enters Power Save mode for WMM associations independent of whether the AP has UAPSD enabledor disabled.
Disabled. The wireless client does not have WMM association.
-------------------------------------------------------------------------------
IBSS Mode
IBSS Mode is used to set the connection type in an ad hoc network. The following options are available for single-band (2.4 GHz band) adapters:

802.11b Only (default) Links with IEEE 802.11b networks at up to 11Mbps.
802.11b/gAuto Links with IEEE 802.11g and 802.11b networks at up
to 54Mbps.

The following options are available for dual-band (2.4GHz and 5GHz) adapters:

802.11b Only (default) Links with IEEE 802.11b networks at up to 11Mbps
or 802.11a at up to 54Mbps.
802.11a/b/g Auto Links with IEEE 802.11g, 802.11b, and 802.11a
networks at up to 54Mbps.
802.11a/b/g/nAuto Links with Draft IEEE 802.11n, 802.11g, 802.11b
and 802.11a networks at up to 270Mbps.

NOTE: The "802.11a/b/g/n Auto" setting is only available for Dell Wireless WLAN cards that are Draft 802.11n capable. If your Dell Wireless WLAN card supports Draft 802.11n operation, you can connect to Draft IEEE 802.11n IBSS networks. The maximum rate achievable for a Draft IEEE 802.11n IBSSassociation is 270Mbps, but this is only achievable when joining a Draft IEEE 802.11n IBSS that was established to operate within a 40MHz bandwidth. The maximum rate for most Draft IEEE 802.11n IBSS networks will be 130Mbps. The maximum rate for Draft IEEE 802.11n IBSS networks founded by a Dell Wireless WLAN card is 130Mbps.-------------------------------------------------------------------------------

VLAN Priority Mode (also know as VLAN Priority Support)

The VLAN Priority Mode property controls the introduction of VLAN-tagged packets to send priority information when your network connection is associated to non-QoS infrastructure devices. When this property is set to Auto or On, the NDIS driver always advertises QoS regardless of whether the WMM property is enabled or...
