iwn driver provides support for Intel Wireless WiFi
  Link 4965/5000/1000 and Centrino Wireless-N 1000/2000/6000 Series PCIe Mini
  Card network adapters.
The Intel Wireless WiFi Link 4965AGN (codenamed Kedron) is a PCIe Mini Card network adapter that operates in the 2GHz and 5GHz spectra. It has 2 transmit paths and 3 receiver paths (2T3R). It is part of the fourth-generation Centrino platform (codenamed Santa Rosa).
The Intel WiFi Link 5000 series is a family of wireless network
    adapters that operate in the 2GHz and 5GHz spectra. They are part of the
    fifth-generation Centrino platform (codenamed Montevina). These adapters are
    available in both PCIe Mini Card (model code ending by MMW) and PCIe Half
    Mini Card (model code ending by HMW) form factor. The
    iwn driver provides support for the 5100 (codenamed
    Shirley Peak 1x2), 5150 (codenamed Echo Peak-V), 5300 (codenamed Shirley
    Peak 3x3) and 5350 (codenamed Echo Peak-P) adapters. The 5100 and 5150
    adapters have 1 transmit path and 2 receiver paths (1T2R). The 5300 and 5350
    adapters have 3 transmit paths and 3 receiver paths (3T3R).
The Intel WiFi Link 1000 (codenamed Condor Peak) is a single-chip wireless network adapter that operates in the 2GHz spectrum. It is part of the sixth-generation Centrino platform (codenamed Calpella). It is available in both PCIe Mini Card (model code ending by MMW) and PCIe Half Mini Card (model code ending by HMW) form factor. It has 1 transmit path and 2 receiver paths (1T2R).
The Intel Centrino Ultimate-N 6300 (codenamed Puma Peak 3x3) is a single-chip wireless network adapter that operates in the 2GHz and 5GHz spectra. It has 3 transmit paths and 3 receiver paths (3T3R). The Intel Centrino Advanced-N 6250 (codenamed Kilmer Peak) is a combo WiFi/WiMAX network adapter that operates in the 2GHz and 5GHz spectra. It has 2 transmit paths and 2 receiver paths (2T2R). The Intel Centrino Advanced-N 6200 (codenamed Puma Peak 2x2) is a wireless network adapter that operates in the 2GHz and 5GHz spectra. It has 2 transmit paths and 2 receiver paths (2T2R). These adapters are part of the sixth-generation Centrino platform (codenamed Calpella).
The Intel Centrino Wireless-N 2230 (codename Jackson Peak) and Intel Centrino Wireless-N 2200 (codename Marble Peak) are wireless network adapters that operate in the 2GHz spectrum. These adapters have 2 transmit paths and 2 receiver paths (2T2R). The Intel Centrino Wireless-N 135 and Intel Centrino Wireless-N 105 (codename Canyon Peak) also operate in the 2GHz spectrum. These adapters have 1 transmit path and 1 receiver path (1T1R).
By default, the iwn driver configures the
    adapter for BSS operation (aka infrastructure mode). This mode requires the
    use of an access point.
For more information on configuring this device, see ifconfig(8).
iwn driver can be configured at runtime with
  ifconfig(8) using the
  following parameters:
bssid
    bssid-bssidchan
    n-chanmedia
    mediaiwn driver supports the following
      media types:
    
    autoselectmediaopt
    optsiwn driver supports the following media
      options:
    
    monitor-mediaopt
    optsmode
    modeiwn driver supports the following modes:
    
    
  nwid
    idiwn driver uses an empty string. Note that network
      ID is synonymous with Extended Service Set ID (ESSID).nwkey
    keyiwn is capable of using both 40-bit (5 characters
      or 10 hexadecimal digits) or 104-bit (13 characters or 26 hexadecimal
      digits) keys.-nwkeydhcp NONE NONE NONE nwkey 0x1deadbeef1 chan 11
Configure iwn0 for WEP, using hex key “0x1deadbeef1”:
# ifconfig iwn0 nwkey 0x1deadbeef1
Return iwn0 to its default settings:
# ifconfig iwn0 -bssid -chan media autoselect \ nwid "" -nwkey
Join an existing BSS network, “my_net”:
# ifconfig iwn0 192.168.1.1 netmask 0xffffff00 nwid my_net
