The Silver and the Gold cards of the 65WaveLAN/IEEE also support WEP. Unlike the other IEEE 802.11 network cards, 66the WaveLAN Gold cards accept 104 bits key (13 characters) for WEP 67encryption. The Intersil PRISM-II controller supports WEP as well. 68.Pp 69The 70.Nm 71driver encapsulates all IP and ARP traffic as 802.11 frames, however 72it can receive either 802.11 or 802.3 frames. 73Transmit speed is selectable between 1Mbps fixed, 742Mbps fixed or 2Mbps with auto fallback. 75For WaveLAN/IEEE Turbo adapters, speeds up to 6Mbps are available. 76For WaveLAN/IEEE Turbo 11Mbps adapters and PRISM-II adapters, speeds up to 7711Mbps are available. 78.Pp 79The 80.Nm 81driver supports configuration of Lucent cards for special ad-hoc operation. 82In this mode, the nwid is ignored and stations can communicate among each 83other without the aid of an access point. Note that this mode is specific 84to Lucent chips, and not in the IEEE 802.11 specification. Due to changes 85in the implementation of this special ad-hoc mode, Lucent-based cards with 86different firmware revisions may not interoperate in this mode. This mode 87is no longer the default and must be selected using the 88.Xr ifconfig 8 89.Pq media option Dq adhoc,flag0 90or 91.Xr wiconfig 8 92utilities. 93.Pp 94Recent versions of Lucent and PRISM-II firmware support IBSS creation. 95IBSS is the standard IEEE 802.11 ad-hoc mode. In this mode, the nwid 96should be specified. At least one node must be able to create IBSS. 97The IBSS mode is enabled by 98.Dq adhoc 99or 100.Dq ibss 101media option. 102The IBSS creation is automatically enabled if supported. 103.Pp 104Recent versions of PRISM-II firmware support operating as an 802.11 105Access Point. In this mode, the Access Point station should set the 106nwid. This will create a standard 802.11 network, and the Access Point 107station will show up in an Access Point scan. This mode is enabled 108using the 109.Dq hostap 110media option. 111.Pp 112For more information on configuring this device, see 113.Xr ifconfig 8 114and 115.Xr ifmedia 4 . 116.Sh HARDWARE 117Cards supported by the 118.Nm 119driver include: 120.Pp 121.Bl -item -offset indent -compact 122.It 123Lucent Wavelan/IEEE 2.0Mb Bronze 124.It 125Lucent Wavelan/IEEE 2.0Mb Silver 126.It 127Lucent WaveLAN/IEEE Turbo 128.It 129Lucent WaveLAN/IEEE Turbo 11Mbps 130.It 131Melco AIR CONNECT WLI-PCM-L11, WLI-PCM-L11G 132.It 133Melco AIR CONNECT WLI-CF-S11G 134.It 135Compaq WL100 11Mbps Wireless 136.It 137Corega Wireless LAN PCC-11, PCCA_11, PCCB_11 138.It 139DEC/Cabletron RoamAbout 802.11 DS High Rate 140.It 141D-Link DWL-650 11Mbps WLAN Card, DCF-650W CF Card 142.It 143ELECOM Air@Hawk LD-WL11 144.It 145ELSA AirLancer MC-11 146.It 147Ericsson Wireless LAN 148.It 149Farallon Skyline 11Mbps Wireless 150.It 151Intel PRO/Wireless 2011 LAN PC Card 152.It 153ICOM SL-1100 154.It 155IO-DATA WN-B11/PCM 156.It 157Intersil PRISM Mini-PCI 158.It 159Linksys Group, Inc.
