+.Sh NAME
+.Nm run
+.Nd Ralink Technology/MediaTek USB IEEE 802.11a/b/g/n wireless network device
+.Sh SYNOPSIS
+.Cd "run* at uhub? port ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports USB 2.0 wireless adapters based on the Ralink RT2700U,
+RT2800U, RT3000U and RT3900E chipsets.
+.Pp
+The RT2700U chipset consists of two integrated chips, an RT2770 MAC/BBP and
+an RT2720 (1T2R) or RT2750 (dual-band 1T2R) radio transceiver.
+.Pp
+The RT2800U chipset consists of two integrated chips, an RT2870 MAC/BBP and
+an RT2820 (2T3R) or RT2850 (dual-band 2T3R) radio transceiver.
+.Pp
+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.
+.Pp
+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.
+.Pp
+These are the modes the
+.Nm
+driver can operate in:
+.Bl -tag -width "IBSS-masterXX"
+.It BSS mode
+Also known as
+.Em infrastructure
+mode, this is used when associating with an access point, through
+which all traffic passes.
+This mode is the default.
+.It monitor mode
+In this mode the driver is able to receive packets without
+associating with an access point.
+This disables the internal receive filter and enables the card to
+capture packets from networks which it wouldn't normally have access to,
+or to scan for access points.
+.El
+.Pp
+The
+.Nm
+driver can be configured to use
+Wired Equivalent Privacy (WEP) or
+Wi-Fi Protected Access (WPA1 and WPA2).
+WPA2 is currently the most secure encryption standard for wireless networks
+supported by
+.Ox .
+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
+.Qq Cm wpaprotos Ar wpa1,wpa2 .
+For standard WPA networks which use pre-shared keys (PSK),
+keys are configured using the
+.Qq Cm wpakey
+option.
+WPA-Enterprise networks require use of the wpa_supplicant package.
+The
+.Nm
+driver offloads both encryption and decryption of data frames to the
+hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP ciphers.
+.Pp
+The
+.Nm
+driver can be configured at runtime with
+.Xr ifconfig 8
+or on boot with
+.Xr hostname.if 5 .
+.Sh FILES
+The driver needs the following firmware files,
+which are loaded when an interface is brought up:

+.Sh DIAGNOSTICS
+.Bl -diag
+.It "run0: error N, could not read firmware ..."
+For some reason, the driver was unable to read the microcode file from the
+filesystem.
+The file might be missing or corrupted.
+.It "run0: could not load 8051 microcode"
+An error occurred while attempting to upload the microcode to the onboard 8051
+microcontroller unit.
+.It "run0: device timeout"
+A frame dispatched to the hardware for transmission did not complete in time.
+The driver will reset the hardware.
+This should not happen.
