NAME

ural — Ralink Technology RT2500USB IEEE 802.11 driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configura‐ tion file: device ehci device uhci device ohci device usb device ural device wlan device wlan_amrr Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_ural_load="YES"

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 trans‐ ceiver (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 inter‐ face may be configured at any time. For more information on configuring this device, see ifconfig(8).

EXAMPLES

Join an existing BSS network (i.e., connect to an access point): ifconfig wlan create wlandev ural0 inet 192.168.0.20 \ netmask 0xffffff00 Join a specific BSS network with network name “my_net”: ifconfig wlan create wlandev ural0 ssid my_net up Join a specific BSS network with 64-bit WEP encryption: ifconfig wlan create wlandev ural0 ssid my_net \ wepmode on wepkey 0x1234567890 weptxkey 1 up Join a specific BSS network with 128-bit WEP encryption: ifconfig wlan create wlandev ural0 wlanmode adhoc ssid my_net \ wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS
