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.
The following adapters should work:
