run — Ralink
Technology/MediaTek USB IEEE 802.11a/b/g/n wireless network
run* at uhub? port ?
run driver supports USB 2.0 wireless
adapters based on the Ralink RT2700U, RT2800U, RT3000U and RT3900E
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.
The RT3900E is a single-chip solution based on an RT3593, RT5390, RT5392 or an RT5592 MAC/BBP and an RT3053 (dual-band 3T3R), RT5370 (1T1R), RT5372 (2T2R), or RT5572 (dual-band 2T2R) radio transceiver.
These are the modes the
run driver can
run driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA1 and WPA2).
WPA2 is the current encryption standard for wireless networks. It is
strongly recommended that neither WEP nor WPA1 are used as the sole
mechanism to secure wireless communication, due to serious weaknesses. WPA1
is disabled by default and may be enabled using the option
wpa1,wpa2". For standard WPA networks which use
pre-shared keys (PSK), keys are configured using the
wpakey" option. WPA-Enterprise networks
require use of the wpa_supplicant package. The
driver offloads both encryption and decryption of data frames to the
hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP ciphers.
The driver needs the following firmware files, which are loaded when an interface is brought up:
The following adapters should work:
The following example scans for available networks:
# ifconfig run0 scan
The following hostname.if(5) example configures run0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
nwid mynwid wpakey mywpakey inet autoconf
run driver first appeared in
run driver was written by
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.
This driver does not support powersave mode.
