# rum.4

`rum` — Ralink Technology USB IEEE 802.11a/b/g 无线网络驱动

## 名称

`rum`

## 概要

若要将此驱动程序编译进内核，请在你的内核配置文件中加入以下行：

> device ehci device uhci device ohci device usb device rum device wlan device wlan\_amrr

或者，若要在引导时以模块方式加载驱动程序，在 loader.conf(5) 中加入以下行：

```sh
if_rum_load="YES"
```

## 描述

`rum` 驱动支持基于 Ralink RT2501USB 和 RT2601USB 芯片组的 USB 2.0 和 PCI Express Mini Card 无线适配器。

Ralink PCI Express Mini Card 适配器显示为普通 USB 2.0 设备，因此由 `rum` 驱动处理。

RT2501USB 芯片组是 Ralink 的第二代 802.11a/b/g 适配器。它由两块集成芯片组成：一块 RT2571W MAC/BBP 和一块 RT2528 或 RT5226 无线电收发器。

RT2601USB 芯片组由两块集成芯片组成：一块 RT2671 MAC/BBP 和一块 RT2527 或 RT5225 无线电收发器。此芯片组使用 MIMO（多输入多输出）技术和多个天线扩展适配器的工作范围并实现更高的吞吐量。

所有芯片均有硬件支持 WEP、AES-CCM、TKIP 和 Michael 加密操作。

`rum` 支持 `station`、`adhoc`、`adhoc-demo`、`hostap` 和 `monitor` 模式操作。同一时间只能配置一个虚拟接口。有关配置此设备的更多信息，参见 [ifconfig(8)](/man/man8/ifconfig.8.md)。

## 实例

加入现有的 BSS 网络（即连接到接入点）：

```sh
ifconfig wlan create wlandev rum0 inet 192.0.2.20/24
```

加入网络名为 `my_net` 的特定 BSS 网络：

```sh
ifconfig wlan create wlandev rum0 ssid my_net up
```

加入使用 64 位 WEP 加密的特定 BSS 网络：

```sh
ifconfig wlan create wlandev rum0 ssid my_net e
    wepmode on wepkey 0x1234567890 weptxkey 1 up
```

加入使用 128 位 WEP 加密的特定 BSS 网络：

```sh
ifconfig wlan create wlandev rum0 wlanmode adhoc ssid my_net e
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
```

## 诊断

* rum%d: could not load 8051 microcode 尝试向板载 8051 微控制器单元上传微代码时发生错误。驱动将重置硬件。这不应发生。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/rum.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.
