29 driver provides support for
31 Wireless WiFi Link 4965AGN Mini PCI Express network adapters.
35 driver configures the adapter for BSS operation (aka infrastructure mode).
36 This mode requires the use of an access point.
38 For more information on configuring this device, see
43 driver can be configured at runtime with
45 using the following parameters:
48 Set the desired BSSID.
50 Unset the desired BSSID.
51 The interface will automatically select a BSSID in this mode, which is

102 or a series of hexadecimal digits up to 64 digits.
105 string allows the interface to connect to any available access points.
108 driver uses an empty string.
