DESCRIPTION

The ural driver supports USB 2.0 wireless adapters based on the RT2500USB chipset.

The RT2500USB chipset consists of two integrated chips, a RT2570 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).

ural supports station, adhoc, hostap, and monitor mode operation. Only one virtual interface may be configured at any time. For more information on configuring this device, see ifconfig(8).

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).
