Usage

Overview

The ral driver supports PCI/CardBus wireless adapters based on the Ralink RT2500 chipset.

The RT2500 chipset consists of two integrated chips, a RT2560 MAC/BBP and a radio transceiver (the model of which depends on the card revision).

The RT2522, RT2523, RT2524, RT2525, RT2525e and RT2526 radio transceivers operate in the 2.4GHz band (802.11b/g) whereas the RT5222 is a dual-band radio transceiver that can operate in the 2.4GHz and 5.2GHz bands (802.11a).

The transmit speed is user-selectable or can be adapted automatically by the driver depending on the received-signal strength.

Hardware

The following adapters should work:

Examples

Join an existing BSS network (i.e., connect to an access point):

ifconfig ral0 inet 192.168.0.20 netmask 0xffffff00

Join a specific BSS network with network name “my_net”:

ifconfig ral0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

Join a specific BSS network with 40-bit WEP encryption:

ifconfig ral0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
    wepmode on wepkey 0x1234567890

Join a specific BSS network with 104-bit WEP encryption:

ifconfig ral0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
    wepmode on wepkey 0x01020304050607080910111213

Diagnostics

ral%d: device timeout

The driver will reset the hardware. This should not happen.

Caveats

PCI ral adapters seem to require a PCI 2.2 compliant motherboard and will likely not work with PCI 2.1 only motherboard.
