.Nd "Mediatek MT7601U"
.Ed
.Sh DESCRIPTION
This module provides support for Mediatek MT7601U with the firmware from net/wifi-firmware-mtw-kmod
.Sh HARDWARE
The
.Nm
driver supports Mediatek MT7601U
based USB wireless network adapters including (but not all of them tested):
.Pp
.Bl -column -compact
.It
ASUS USB-N10 v2
.It
D-Link DWA-127 rev B1
.It
Edimax EW-7711UAn v2
.It
Foxconn WFU03
.It
Tenda U2
.It
Tenda W311MI v2
.It
TP-LINK TL-WN727N v4 (tested working)
.It
Yealink WF40
.El
.Sh SEE ALSO
.Xr usb 4
.Sh BUGS
The
.Nm
only works in station mode and monitor mode. The firmware does not always reinitialize when reloading the module, or when rebooting, without first unplugging the device.
.Sh History
The mtw driver first appeared in OpenBSD 7.1. The mtw driver was ported to FreeBSD in FreeBSD 15.0.
.Sh AUTHORS
.An -nosplit
The mtw driver was written by
.An James Hastings Aq Mt hastings@openbsd.org
ported to FreeBSD by
.An Jesper Schmitz Mouridsen Aq Mt jsm@FreeBSD.org
