+
+## Overview
+
+The ap collector visualizes data related to wireless access points.
+
+It uses the `iw` command line utility to detect access points. For each interface that is of `type AP`, it then runs `iw INTERFACE station dump` and collects statistics.
+
+This collector is only supported on the following platforms:
+
+- Linux
+
+This collector only supports collecting metrics from a single instance of this integration.
+
+
+### Default Behavior
+
+#### Auto-Detection
+
+The plugin is able to auto-detect if you are running access points on your linux box.
+
+#### Limits
+
+The default configuration for this integration does not impose any limits on data collection.
+
+#### Performance Impact
+
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
+
+
+## Metrics
+
+Metrics grouped by *scope*.
+
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
+
+
+
+### Per wireless device
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| ap.clients | clients | clients |
+| ap.net | received, sent | kilobits/s |
+| ap.packets | received, sent | packets/s |
+| ap.issues | retries, failures | issues/s |
+| ap.signal | average signal | dBm |
+| ap.bitrate | receive, transmit, expected | Mbps |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
+
+#### Install charts.d plugin
+
+If [using our official native DEB/RPM packages](/packaging/installer/UPDATE.md#determine-which-installation-method-you-used), make sure `netdata-plugin-chartsd` is installed.
+
+
+#### `iw` utility.
+
+Make sure the `iw` utility is installed.
+
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `charts.d/ap.conf`.
+
+
+You can edit the configuration file using the `edit-config` script from the
+Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config charts.d/ap.conf
+```
+#### Options
+
+The config file is sourced by the charts.d plugin. It's a standard bash file.
+
+The following collapsed table contains all the options that can be configured for the ap collector.
+
+
+<details open><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| ap_update_every | The data collection frequency. If unset, will inherit the netdata update frequency. | 1 | no |
+| ap_priority | Controls the order of charts at the netdata dashboard. | 6900 | no |
+| ap_retries | The number of retries to do in case of failure before disabling the collector. | 10 | no |
+
+</details>
+
+#### Examples
+
+##### Change the collection frequency
+
+Specify a custom collection frequence (update_every) for this collector
+
+```yaml
+# the data collection frequency
+# if unset, will inherit the netdata update frequency
+ap_update_every=10
+
+# the charts priority on the dashboard
+#ap_priority=6900
+
+# the number of retries to do in case of failure
+# before disabling the module
+#ap_retries=10
+
+```
+
+
+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `ap` collector, run the `charts.d.plugin` with the debug option enabled. The output
+should give you clues as to why the collector isn't working.
+
+- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
+  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
+
+  ```bash
+  cd /usr/libexec/netdata/plugins.d/
+  ```
+
+- Switch to the `netdata` user.
+
+  ```bash
+  sudo -u netdata -s
+  ```
+
+- Run the `charts.d.plugin` to debug the collector:
+
+  ```bash
+  ./charts.d.plugin debug 1 ap
+  ```
+
+
