wi - WaveLAN/IEEE and PRISM-II 802.11 wireless network driver
wi* at pcmcia? function ? wi* at pci? dev ? function ?
The wi driver provides support for Lucent Technologies WaveLAN/IEEE PC- CARD adapters (also known as WaveLAN II cards) and various PCCARD adapters which use Intersil PRISM-II and PRISM-2.5 chipsets. Note that while Lucent sells both ISA and PCMCIA WaveLAN/IEEE devices, the ISA product is actually a PCMCIA card in an ISA to PCMCIA bridge adapter. Consequently, the wi driver is required for both the ISA and PCMCIA NICs. Also note that some of the PRISM-II adapters works only at 3.3V, hence cardbus(4) support is required for those cards to set VCC correctly, even they are 16bit cards. The core of the WaveLAN/IEEE is the Lucent Hermes controller. All host/device interaction is via programmed I/O with the Hermes. The Her- mes supports 802.11 and 802.3 frames, power management, BSS, WDS and ad- hoc operation modes. The Silver and the Gold cards of the WaveLAN/IEEE also support WEP. Unlike the other IEEE 802.11 network cards, the Wave- LAN Gold cards accept 104 bits key (13 characters) for WEP encryption. The Intersil PRISM-II controller supports WEP as well. The wi driver encapsulates all IP and ARP traffic as 802.11 frames, how- ever it can receive either 802.11 or 802.3 frames. Transmit speed is se- lectable between 1Mbps fixed, 2Mbps fixed or 2Mbps with auto fallback. For WaveLAN/IEEE Turbo adapters, speeds up to 6Mbps are available. For WaveLAN/IEEE Turbo 11Mbps adapters and PRISM-II adapters, speeds up to 11Mbps are available. The wi driver supports configuration of WaveLAN card for special ad-hoc operation. In this mode, the nwid is ignored and stations can communi- cate among each other without the aid of an access point. Note that this mode is not in the IEEE 802.11 specification and the driver may interop- erate with other cards. This mode is no longer the default and must be selected using the ifconfig(8) or wiconfig(8) utilities. For more information on configuring this device, see ifconfig(8) and ifmedia(4).

wi%d: init failed The WaveLAN failed to come ready after an initializa- tion command was issued. wi%d: failed to allocate %d bytes on NIC The driver was unable to allo- cate memory for transmit frames in the NIC's on-board RAM. wi%d: device timeout The WaveLAN failed to generate an interrupt to ac- knowledge a transmit command. One reason can be that the board is mis- configured, see wiconfig(8).

The wi device driver first appeared in NetBSD 1.5.
The wi driver was written by Bill Paul <wpaul@ctr.columbia.edu>.
The IBSS mode is not supported. PRISM chipset does not have IBSS mode. The execution of wiconfig(8) while the interface is down can produce some error messages. NetBSD 1.6.2 January 11, 2001 2
