+# Access Point Plugin (ap)
+
+The `ap` collector visualizes data related to access points.
+
+## Example netdata charts

+
+## How it works
+
+It does the following:
+
+1. Runs `iw dev` searching for interfaces that have `type AP`.
+
+ From the same output it collects the SSIDs each AP supports by looking for lines `ssid NAME`.
+
+ Example:
+```sh
+# iw dev
+phy#0
+ Interface wlan0
+ ifindex 3
+ wdev 0x1
+ addr 7c:dd:90:77:34:2a
+ ssid TSAOUSIS
+ type AP
+ channel 7 (2442 MHz), width: 20 MHz, center1: 2442 MHz
+```
+
+
+2. For each interface found, it runs `iw INTERFACE station dump`.
+
+ From the output is collects:
+
+ - rx/tx bytes
+ - rx/tx packets
+ - tx retries
+ - tx failed
+ - signal strength
+ - rx/tx bitrate
+ - expected throughput
+
+ Example:
+
+```sh
+# iw wlan0 station dump
+Station 40:b8:37:5a:ed:5e (on wlan0)
+ inactive time: 910 ms
+ rx bytes: 15588897
+ rx packets: 127772
+ tx bytes: 52257763
+ tx packets: 95802
+ tx retries: 2162
+ tx failed: 28
+ signal: -43 dBm
+ signal avg: -43 dBm
+ tx bitrate: 65.0 MBit/s MCS 7
+ rx bitrate: 1.0 MBit/s
+ expected throughput: 32.125Mbps
+ authorized: yes
+ authenticated: yes
+ preamble: long
+ WMM/WME: yes
+ MFP: no
+ TDLS peer: no
+```
+
+3. For each interface found, it creates 6 charts:
+
+ - Number of Connected clients
+ - Bandwidth for all clients
+ - Packets for all clients
+ - Transmit Issues for all clients
+ - Average Signal among all clients
+ - Average Bitrate (including average expected throughput) among all clients
+
+## Configuration
+
+You can only set `ap_update_every=NUMBER` to `/etc/netdata/charts.d/ap.conf`, to give the data collection frequency.
+To edit this file on your system run `/etc/netdata/edit-config charts.d/ap.conf`.
+
+## Auto-detection
+
+The plugin is able to auto-detect if you are running access points on your linux box.
