     acx - TI ACX100/ACX111 IEEE 802.11a/b/g wireless network device

     acx* at cardbus?
     acx* at pci?

     The acx driver provides support for TI TNETW1100/TNETW1100B (ACX100) and
     TNETW1130 (ACX111) based PCI/CardBus network adapters.

     The ACX100A and ACX100B are first generation 802.11b devices from TI.
     The ACX111 is a second generation device which supports 802.11b/g and in
     some cases 802.11a.

     These are the modes the acx driver can operate in:

     BSS mode	    Also known as infrastructure mode, this is used when
		    associating with an access point, through which all
		    traffic passes.  This mode is the default.

     IBSS mode	    Also known as IEEE ad-hoc mode or peer-to-peer mode.  This
		    is the standardized method of operating without an access
		    point.  Stations associate with a service set.  However,
		    actual connections between stations are peer-to-peer.

     Host AP	    In this mode the driver acts as an access point (base
		    station) for other cards.

     monitor mode   In this mode the driver is able to receive packets without
		    associating with an access point.  This disables the
		    internal receive filter and enables the card to capture
		    packets from networks which it wouldn't normally have
		    access to, or to scan for access points.

     The acx driver can be configured to use Wired Equivalent Privacy (WEP) in
     software for ACX111 or in hardware for ACX100.  It is strongly
     recommended that WEP not be used as the sole mechanism to secure wireless
     communication, due to serious weaknesses in it.

     The transmit speed is user-selectable or can be adapted automatically by
     the driver depending on the number of hardware transmission retries.

     The acx driver can be configured at runtime with ifconfig(8) or on boot
     with hostname.if(5).

     The driver needs a set of firmware files which are loaded when an
     interface is brought up:


     These firmware files are not free because TI refuses to grant
     distribution rights.  In fact they have rebuffed thousands of attempts to
     start a dialogue on this issue.  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:

     The following cards are among those supported by the acx driver:

     Card		 Chip	Bus	Standard
     D-Link DWL-520+	 ACX100 PCI	b
     D-Link DWL-650+	 ACX100 CardBus b
     D-Link DWL-G520+	 ACX111 PCI	b/g
     D-Link DWL-G630+	 ACX111 CardBus b/g
     D-Link DWL-G650+	 ACX111 CardBus b/g
     Digitus DN-7001G	 ACX111 CardBus b/g
     Ergenic ERG WL-003	 ACX100 CardBus b
     Hamlet HNWP254	 ACX111 CardBus b/g
     Hawking HWP54G	 ACX111 PCI	b/g
     Linksys WPC54Gv2	 ACX111 CardBus b/g
     Microcom Travelcard ACX111 CardBus b/g
     Netgear WG311v2	 ACX111 PCI	b/g
     Sceptre SC254W+	 ACX111 CardBus b/g
     Tornado/ADT 211g	 ACX111 PCI	b/g
     USR USR5410	 ACX111 CardBus b/g
     USR USR5416	 ACX111 PCI	b/g
     ZyXEL G-160	 ACX111 CardBus b/g
     ZyXEL G-360 EE	 ACX111 PCI	b/g

     The following hostname.if(5) example configures acx0 to join whatever
     network is available on boot, using WEP key ``0x1deadbeef1'', channel 11,
     obtaining an IP address using DHCP:

	   dhcp NONE NONE NONE nwkey 0x1deadbeef1 chan 11

     The following hostname.if(5) example creates a host-based access point on

	   inet NONE media autoselect \
		   mediaopt hostap nwid my_net chan 11

     Configure acx0 for WEP, using hex key ``0x1deadbeef1'':

	   # ifconfig acx0 nwkey 0x1deadbeef1

     Return acx0 to its default settings:

	   # ifconfig acx0 -bssid -chan media autoselect \
		   nwid "" -nwkey

     Join an existing BSS network, ``my_net'':

	   # ifconfig acx0 netmask 0xffffff00 nwid my_net

     arp(4), cardbus(4), ifmedia(4), intro(4), netintro(4), pci(4),
     hostname.if(5), hostapd(8), ifconfig(8)

     The acx driver first appeared in OpenBSD 4.0.

     The acx driver was written by Sepherosa Ziehau.  The manual page was
     written by Sascha Wildner.	 Both are based on the
     project team's original code.

     The hardware specification was reverse engineered by the good folks at  Without them this driver would not have
     been possible.

     Host AP mode doesn't support power saving.	 Clients attempting to use
     power saving mode may experience significant packet loss (disabling power
     saving on the client will fix this).
