run
— Ralink
Technology USB IEEE 802.11a/b/g/n wireless network device
run* at uhub? port ?
The run
driver supports USB 2.0 wireless
adapters based on the Ralink RT2700U, RT2800U and RT3000U chipsets.
The RT2700U chipset consists of two integrated chips, an RT2770 MAC/BBP and an RT2720 (1T2R) or RT2750 (dual-band 1T2R) radio transceiver.
The RT2800U chipset consists of two integrated chips, an RT2870 MAC/BBP and an RT2820 (2T3R) or RT2850 (dual-band 2T3R) radio transceiver.
The RT3000U is a single-chip solution based on an RT3070 MAC/BBP and an RT3020 (1T1R), RT3021 (1T2R), RT3022 (2T2R) or RT3052 (dual-band 2T2R) radio transceiver.
These are the modes the run
driver can
operate in:
The run
driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and
WPA2-PSK). WPA is the de facto encryption standard for wireless networks. It
is strongly recommended that WEP not be used as the sole mechanism to secure
wireless communication, due to serious weaknesses in it. The
run
driver offloads both encryption and decryption
of data frames to the hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP
ciphers.
The run
driver can be configured at
runtime with ifconfig(8) or
on boot with
ifconfig.if(5).
The driver needs the following firmware files, which are loaded when an interface is brought up:
The following adapters should work:
The following ifconfig.if(5) example configures run0 to join whatever network is available on boot, using WEP key “0x1deadbeef1”, channel 11, obtaining an IP address using DHCP:
dhcp NONE NONE NONE nwkey 0x1deadbeef1 chan 11
Join an existing BSS network, “my_net”:
# ifconfig run0 192.168.1.1 netmask 0xffffff00 nwid my_net
arp(4), ifmedia(4), netintro(4), usb(4), ifconfig.if(5), wpa_supplicant.conf(5), ifconfig(8), wpa_supplicant(8)

The run
driver first appeared in
OpenBSD 4.5 and in NetBSD
7.0.
The run
driver was written by
Damien Bergamini ⟨damien@openbsd.org⟩
for OpenBSD and ported to
NetBSD by FUKAUMI Naoki.
The run
driver does not support any of the
802.11n capabilities offered by the RT2800 and RT3000 chipsets. Additional
work is required in
ieee80211(9) before those
features can be supported.
