# mtw(4)

MediaTek MT7601U USB IEEE 802.11n wireless network driver

Part of [if\_mtw(4)](/if_mtw/4.md).

## NAME

**mtw** – MediaTek MT7601U USB IEEE 802.11n wireless network driver

## SYNOPSIS

**device** **usb** **device** **mtw** **device** **wlan**

In [rc.conf(5)](/rc.conf/5.md): **kld\_list="if\_mtw"**

## DESCRIPTION

This module provides support for MediaTek MT7601U USB wireless network adapters. If the appropriate hardware is detected, the driver will be automatically loaded with [devmatch(8)](/devmatch/8.md). If driver autoloading is explicitly disabled, enable the module in [rc.conf(5)](/rc.conf/5.md). The **mtw** driver can be configured at runtime with [ifconfig(8)](/ifconfig/8.md) or at boot with [rc.conf(5)](/rc.conf/5.md).

## HARDWARE

The **mtw** driver supports MediaTek MT7601U based USB wireless network adapters including (but not all of them tested):

- ASUS USB-N10 v2

- D-Link DWA-127 rev B1

- Edimax EW-7711UAn v2

- Foxconn WFU03

- Tenda U2

- Tenda W311MI v2

- TP-LINK TL-WN727N v4 (tested working)

- Yealink WF40

## FILES

The **mtw** driver requires firmware from *ports/net/wifi-firmware-mt7601u-kmod*. This firmware package will be installed automatically with [fwget(8)](/fwget/8.md) if the appropriate hardware is detected at installation or runtime.

## SEE ALSO

[usb(4)](/usb/4.md), [wlan(4)](/wlan/4.md), [networking(7)](/networking/7.md), [fwget(8)](/fwget/8.md), [wpa\_supplicant(8)](/wpa_supplicant/8.md)

## HISTORY

The **mtw** driver first appeared in OpenBSD 7.1 and FreeBSD 15.0.

## AUTHORS

The **mtw** driver was written by James Hastings ⟨*hastings@openbsd.org*⟩ and ported to FreeBSD by Jesper Schmitz Mouridsen ⟨*jsm@FreeBSD.org*⟩.

## BUGS

**mtw** 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.
