wi - Lucent Hermes, Intersil PRISM and Spectrum24 IEEE 802.11 driver
device wi device wlan
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:
Supported features include 802.11 and 802.3 frames, power management, BSS, IBSS, WDS and old-style Lucent ad-hoc operation modes. Cards based on the Intersil PRISM chips also support a host-based access point mode which allows a card to act as a normal access point (with some assistance from the driver). The Lucent Hermes and Symbol Spectrum24 chipsets do not contain this functionality. The PRISM family of chips do not support the WDS functionality. All host/device interaction is via programmed I/O, even on those cards that support a DMA interface.
The driver encapsulates all IP and ARP traffic as 802.11 frames, however it can receive either 802.11 or 802.3 frames. Transmit speed is selectable between 1Mbps, 2Mbps, 5.5 Mbps and 11Mbps depending on your hardware. Most hardware supports 11Mbps where the signal quality allows, but falls back to slower speeds when it does not. Except for the Lucent WaveLAN Bronze cards, all cards supported by the driver support WEP for encryption. To enable encryption, use ifconfig(8) as shown below.
By default, the driver configures the card for BSS operation (aka infrastructure mode). This mode requires the use of an access point (base station).
The driver also supports a point-to-point mode where stations can communicate amongst themselves without the aid of an access point. Note that there are two possible point-to-point modes. One mode, referred to as ``ad-hoc demo mode'' or ``legacy Lucent ad-hoc mode'' predates the IEEE 802.11 specification and so may not interoperate with cards from different vendors. The standardized point-to-point mode is called IBSS (or confusingly just ad-hoc mode), but is not supported by cards with very old firmware revisions. If your cards supports IBSS mode, it is recommended that you use it in preference to the ``ad-hoc demo mode'' in new installations.
Cards supported by the driver based on the Intersil PRISM family of chips also have a host-based access point mode which allows the card to act as an access point (base station). Access points are different than operating in IBSS mode. They operate in BSS mode. They allow for easier roaming and bridge all Ethernet traffic such that machines connected via an access point appear to be on the local Ethernet segment.
For more information on configuring this device, see ifconfig(8).
Cards supported by the driver come in a variety of packages, though the most common are of the PCMCIA type. In many cases, the PCI version of a wireless card is simply a PCMCIA card bundled with a PCI adapter. The PCI adapters come in two flavors: true PCMCIA bridges and dumb PCMCIA bridges. A true PCMCIA bridge (such as those sold by Lucent) will attach as a real PCMCIA controller. The wireless card will then attach to the PCMCIA bus. Wireless cards in PCMCIA slots may be inserted and ejected on the fly.
A dumb bridge, on the other hand, does not show up as a true PCMCIA bus. The wireless card will simply appear to the host as a normal PCI device and will not require any PCMCIA support. Cards in this type of adapter should only be removed when the machine is powered down.

Several vendors sell PCI adapters built around the PLX Technology 9050 or 9052 chip. The following such adapters are supported or expected to work:
The following adapters have the same model numbers as those listed above, but might not work if the actual card is after the change away from the Prism family:
"ifconfig wi0 inet 192.168.0.20 netmask 0xffffff00"
Join a specific BSS network with network name ``my_net ''
"ifconfig wi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net"
Join a specific BSS network with WEP encryption:
ifconfig wi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \ wepmode on wepkey 0x8736639624
Join a Lucent legacy demo ad-hoc network with network name ``my_net ''
ifconfig wi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \ media DS/11Mbps mediaopt adhoc,link0
Join/create an IBSS network with network name ``my_net ''
ifconfig wi0 inet 192.168.0.22 netmask 0xffffff00 ssid my_net \ media DS/11Mbps mediaopt adhoc
Create a host-based access point (Prism only):
ifconfig wi0 inet 192.168.0.10 netmask 0xffffff00 ssid my_ap \ media DS/11Mbps mediaopt hostap
Create a host-based access point with WEP enabled (Prism only):
ifconfig wi0 inet 192.168.0.10 netmask 0xffffff00 ssid my_ap \ wepmode on wepkey 0x1234567890 media DS/11Mbps \ mediaopt hostap
Create a host-based wireless bridge to fxp0 (Prism only):
ifconfig wi0 inet up ssid my_ap media DS/11Mbps mediaopt hostap sysctl net.inet.ip.check_interface=0 ifconfig bridge0 create ifconfig bridge0 addm wi0 addm fxp0 up
This will give you the same functionality as an access point.
Lucent cards prior to firmware version 6.0.6 do not support IBSS mode. These cards support only the pre-802.11 mode known as ``demo ad-hoc mode'' which does not interoperate with stations in IBSS mode.
Prism cards prior to version 0.8.0 do not support IBSS mode.
Symbol cards prior to version 2.50.00 do not support IBSS mode.
WL200 PCI wireless cards are based on a Cirrus Logic CL-PD6729 bridge chips glued to an Intersil Prism-II PCMCIA chipset w/o the PC Card form factor being present. These chips are special and require special care to use properly. One must set hw.pcic.pd6729_intr_path = Qq 2 in /boot/loader.conf This tells the PC Card system to use PCI interrupts for this odd beast. It is not possible to know automatically which kind of interrupts to use. OLDCARD devices support this device. NEWCARD devices (pccbb4 and pccard(4)) do not support it at this time.
