NAME
ral -- Ralink Technology IEEE 802.11 wireless network driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device ral device ralfw device wlan device wlan_amrr device firmware Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_ral_load="YES" DESCRIPTION
The ral driver supports PCI/CardBus wireless adapters based on the Ralink Technology RT2500, RT2501, and RT2600 chipsets. The RT2500 chipset is the first generation of 802.11b/g adapters from Ralink. It consists of two integrated chips, a RT2560 MAC/BBP and a RT2525 radio transceiver. The RT2501 chipset is the second generation of 802.11b/g adapters from Ralink. It consists of two integrated chips, a RT2561 MAC/BBP and a RT2527 radio transceiver. This chipset provides support for the IEEE 802.11e standard with multiple hardware transmission queues and allows scatter/gather for efficient DMA operations. The RT2600 chipset consists of two integrated chips, a RT2661 MAC/BBP and a RT2529 radio transceiver. This chipset uses the MIMO (multiple- input multiple-output) technology with multiple antennas to extend the operating range of the adapter and to achieve higher throughput. MIMO is the basis of the forthcoming IEEE 802.11n standard. The transmit speed is user-selectable or can be adapted automatically by the driver depending on the received signal strength and on the num- ber of hardware transmission retries. ral supports station, adhoc, hostap, mesh, wds, and monitor mode operation. Only one hostap or mesh virtual interface may be configured at a time. Any number of wds virtual interfaces may be configured together with a hostap interface. Multiple station interfaces may be operated together with a hostap interface to construct a wireless repeater device. For more information on configuring this device, see ifconfig(8). HARDWARE

ral%d: could not load 8051 microcode An error occurred while attempting to upload the microcode to the onboard 8051 microcontroller unit. ral%d: timeout waiting for MCU to initialize The onboard 8051 microcontroller unit failed to initialize in time. ral%d: device timeout A frame dispatched to the hardware for transmission did not complete in time. The driver will reset the hardware. This should not happen. SEE ALSO

The ral driver first appeared in OpenBSD 3.7. AUTHORS
The original ral driver was written by Damien Bergamini <damien@FreeBSD.org>. BUGS
Host AP mode doesn't support client power save. Clients using power save mode will experience packet loss (disabling power saving on the client will fix this). BSD
