iwn
driver provides support for Intel Wireless WiFi
Link 4965/5000/1000 and 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).
These are the modes the iwn
driver can
operate in:
The iwn
driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and
WPA2-PSK). WPA is the de facto encryption standard for wireless networks. It
is strongly recommended that WEP not be used as the sole mechanism to secure
wireless communication, due to serious weaknesses in it. The
iwn
driver offloads both encryption and decryption
of unicast data frames to the hardware for the CCMP cipher.
The iwn
driver can be configured at
runtime with ifconfig(8) or
on boot with
hostname.if(5).
These firmware files are not free because Intel refuses to grant distribution rights without contractual obligations. As a result, even though OpenBSD includes the driver, the firmware files cannot be included and users have to download these files on their own.
A prepackaged version of the firmware, designed to be used with pkg_add(1), can be found at:

Configure iwn0 to join network “my_net” using WPA with passphrase “my_passphrase”:
# ifconfig iwn0 nwid my_net wpakey my_passphrase
Join an existing BSS network, “my_net”:
# ifconfig iwn0 192.168.1.1 netmask 0xffffff00 nwid my_net
iwn
driver was written by Damien
Bergamini ⟨damien@openbsd.org⟩.
iwn
driver does not support any of the 802.11n
capabilities offered by the adapters. Additional work is required in
ieee80211(9) before those
features can be supported.June 9, 2011 | OpenBSD-5.1 |
