# Configuración de la tarjeta inalámbrica en modo monitor
Preparar, habilitar, verificar y restaurar un adaptador inalámbrico en modo monitor.
Utilice este flujo de trabajo en un adaptador inalámbrico aprobado. El modo monitor puede interrumpir la conexión de red normal del adaptador.
{% hint style="warning" %}
`airmon-ng check kill` detiene servicios que pueden afectar la conectividad. Guarde primero el trabajo activo.
{% endhint %}
### 1. Identifique la interfaz inalámbrica
Liste las interfaces de red disponibles:
```bash
ip a
```
Identifique el nombre del adaptador inalámbrico. Este ejemplo usa `wlx00c0cabd0890`.
### 2. Detenga los procesos en conflicto
Detenga los servicios que pueden interferir con el modo monitor:
```bash
airmon-ng check kill
```
Esto puede detener NetworkManager y desconectar el sistema de WiFi.
### 3. Habilite el modo monitor
Inicie el modo monitor en el adaptador seleccionado:
```bash
airmon-ng start wlx00c0cabd0890
```
La herramienta puede crear o renombrar una interfaz monitor. No asuma un nombre fijo.
### 4. Verifique la interfaz
Confirme que el adaptador muestra `Mode:Monitor`:
```bash
iwconfig
ifconfig wlan0mon up
```
Use el nombre de la interfaz monitor que se muestra en la salida para las tareas posteriores del laboratorio.
### 5. Restablezca el funcionamiento normal
Detenga el modo monitor cuando termine la evaluación. Reemplace `wlan0mon` con el nombre de su interfaz:
```bash
airmon-ng stop wlan0mon
```
Reinicie NetworkManager para restaurar la gestión normal de la red:
```bash
sudo systemctl restart NetworkManager
```
Si la conexión no regresa, vuelva a conectarse a través de NetworkManager después de que se reinicie.

# 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 by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/es/hacking-wifi/wpa-wpa2-psk-network-attacks/fundamentals/configuring-the-wireless-card-in-monitor-mode.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
