# mtw\.4

`mtw` — MediaTek MT7601U USB IEEE 802.11n 无线网络驱动

## 名称

`mtw`

## 概要

`device usb device mtw device wlan`

`在 rc.conf(5) 中：kld_list="if_mtw"`

## 描述

此模块提供对 MediaTek MT7601U USB 无线网络适配器的支持。如果检测到相应硬件，驱动会通过 [devmatch(8)](/man/man8/devmatch.8.md) 自动加载。如果显式禁用了驱动自动加载，请在 [rc.conf(5)](/man/man5/rc.conf.5.md) 中启用该模块。可以在运行时使用 [ifconfig(8)](/man/man8/ifconfig.8.md) 配置 `mtw` 驱动，或在引导时通过 [rc.conf(5)](/man/man5/rc.conf.5.md) 配置。

## 硬件

`mtw` 驱动支持基于 MediaTek MT7601U 的 USB 无线网络适配器，包括（但并非全部经过测试）：

* 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（已测试可用）
* Yealink WF40

## 文件

`mtw` 驱动需要来自 `ports/net/wifi-firmware-mt7601u-kmod` 的固件。如果在安装或运行时检测到相应硬件，此固件包会通过 fwget(8) 自动安装。

## 历史

`mtw` 驱动首次出现于 OpenBSD 7.1 和 FreeBSD 15.0。

## 作者

`mtw` 驱动由 James Hastings <hastings@openbsd.org> 编写，并由 Jesper Schmitz Mouridsen <jsm@FreeBSD.org> 移植到 FreeBSD。

## 缺陷

`mtw` 仅在 `station` 模式和 `monitor` 模式下工作。在重新加载模块或重启时，如果不先拔下设备，固件并不总是会重新初始化。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/mtw.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
