wiconfig -- configure WaveLAN/IEEE devices SYNOPSIS
wiconfig interface [-Dho] [-A 1|2] [-a access_point_density] [-d max_data_length] [-M 0|1] [-R 1|3] [-s station_name] DESCRIPTION
The wiconfig command controls the operation of WaveLAN/IEEE wireless networking devices via the wi(4) and awi(4) drivers. The wiconfig com- mand can also be used to view the current settings of these parameters and to dump out the values of the card's statistics counters. Most of the parameters that can be changed relate to the IEEE 802.11 protocol which the WaveLAN implements. This includes the station name, whether the station is operating in ad-hoc (point to point) or BSS (service set) mode, and the network name of a service set to join (IBSS) if BSS mode is enabled. The interface argument given to wiconfig should be the logical interface name associated with the WaveLAN/IEEE device (e.g., wi0, wi1, etc.). OPTIONS
With no extra options, wiconfig will display the current settings of the specified WaveLAN/IEEE interface. The options are as follows: -A 1|2 Set the authentication type for a specified interface. Permitted values are 1 (Open System Authentication) or 2 (Shared Key Authentication). The default is 1. -a access_point_density Specify the access point density for a given interface. Legal values are 1 (low), 2 (medium), and 3 (high). This setting influ- ences some of the radio modem threshold settings. -D This forces the driver to initiate one round of access point scanning. All of the access points found are displayed. -d max_data_length Set the maximum receive and transmit frame size for a specified interface. The max data length can be any number from 256 to 2346. The default is 2304. -h Display a short help. -M 0|1 Enable or disable "microwave oven robustness" on a given interface. This should only be used if needed. In cases of slow performance where there is a good quality signal but also high levels of noise (i.e., the signal to noise ratio is bad but the signal strength is good), or a microwave oven is operating near the antenna of the WLAN peer or access point, this option may be of use. In bad signal-to-noise conditions, the link layer will switch to lower transmit rates. However at lower transmit rates, individ- ual frames take longer to transmit, making them more vulnerable to bursty noise. The option works by enabling data fragmentation in the link layer as the transmit speed lowers in an attempt to shorten the transmit time of each frame so that individual frames are more likely to be transmitted without error. Note that this does not impact the visible MTU of the link. -o Print out the statistics counters instead of the card settings. Note that, however, the statistics will only be updated every minute or so. -R 1|3 Enable or disable roaming function on a given interface. The legal values are 1 (Roaming handled by firmware) and 3 (Roaming Disabled). The default is 1. -r RTS_threshold -f fragmentation_threshold -m MAC_address These options are deprecated since NetBSD 6.0. Use ifconfig(8) to set the link-layer address, the fragmentation threshold, and the RTS threshold. -s station_name Sets the station_name for the specified interface. The station_name is used for diagnostic purposes. The Lucent WaveMANAGER software can poll the names of remote hosts. SEE ALSO

an -- Aironet Communications 4500/4800 wireless network adapter driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device an device wlan Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_an_load="YES" DESCRIPTION
The an driver provides support for Aironet Communications 4500 and 4800 wireless network adapters and variants, including the following: o Aironet Communications 4500 and 4800 series o Cisco Aironet 340 and 350 series o Xircom Wireless Ethernet Adapter Support for these devices include the ISA, PCI and PCMCIA varieties. The Aironet 4500 series adapters operate at 1 and 2Mbps while the Aironet 4800 series and Cisco adapters can operate at 1, 2, 5.5 and 11Mbps. The ISA, PCI and PCMCIA devices are all based on the same core PCMCIA modules and all have the same programming interface, however unlike the Lucent WaveLAN/IEEE cards, the ISA and PCI cards appear to the host as normal ISA and PCI devices and do not require any PCCARD support. The PCMCIA Aironet cards require PC Card support, including the kernel pccard(4) driver. ISA cards can either be configured to use ISA Plug and Play or to use a particular I/O address and IRQ by properly setting the DIP switches on the board. (The default switch setting is for Plug and Play.) The an driver has Plug and Play support and will work in either configuration, however when using a hard-wired I/O address and IRQ, the driver configuration and the NIC's switch settings must agree. PCI cards require no switch settings of any kind and will be automatically probed and attached. All host/device interaction with the Aironet cards is via programmed I/O. The Aironet devices support 802.11 and 802.3 frames, power manage- ment, BSS (infrastructure) and IBSS (ad-hoc) operation modes. The an 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, 5.5Mbps, 11Mbps or "auto" (the NIC automati- cally chooses the best speed). By default, the an driver configures the Aironet card for infrastructure operation. For more information on configuring this device, see ifconfig(8). DIAGNOSTICS
an%d: init failed The Aironet card failed to become ready after an initialization command was issued. an%d: failed to allocate %d bytes on NIC The driver was unable to allocate memory for transmit frames in the NIC's on-board RAM. an%d: device timeout The Aironet card failed to generate an interrupt to acknowledge a transmit command.
