NAME

rum - Ralink Technology USB IEEE 802.11a/b/g wireless network device

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device ehci device uhci device ohci device usb device rum device wlan device wlan_amrr

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

if_rum_load="YES"

DESCRIPTION

The ifconfig driver supports USB 2.0 and PCI Express Mini Card wireless adapters based on the Ralink RT2501USB and RT2601USB chipsets.

Ralink PCI Express Mini Card adapters show up as normal USB 2.0 devices and are thus handled by the ifconfig driver.

The RT2501USB chipset is the second generation of 802.11a/b/g adapters from Ralink. It consists of two integrated chips, an RT2571W MAC/BBP and an RT2528 or RT5226 radio transceiver.

The RT2601USB chipset consists of two integrated chips, an RT2671 MAC/BBP and an RT2527 or RT5225 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.

ifconfig 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).

EXAMPLES

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

ifconfig wlan create wlandev rum0 inet 192.168.0.20 \
    netmask 0xffffff00

Join a specific BSS network with network name ``my_net ''

"ifconfig wlan create wlandev rum0 ssid my_net up"

Join a specific BSS network with 64-bit WEP encryption:

ifconfig wlan create wlandev rum0 ssid my_net \
        wepmode on wepkey 0x1234567890 weptxkey 1 up

Join a specific BSS network with 128-bit WEP encryption:

ifconfig wlan create wlandev rum0 wlanmode adhoc ssid my_net \
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

"rum%d: could not load 8051 microcode"

An error occurred while attempting to upload the microcode to the onboard 8051 microcontroller unit. The driver will reset the hardware. This should not happen.

HISTORY

The ifconfig driver first appeared in Ox 4.0 .

AUTHORS

The original ifconfig driver was written by An Niall O'Higgins Aq niallo@openbsd.org and An Damien Bergamini Aq damien@openbsd.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).
