## Troubleshooting
### No internet access
If a client is connected to the hotspot and the RaspberryPI is connected to the internet via ethernet but no internet access is available for the client, try to enable IPv4 forwarding in `/etc/sysctl.conf`, reload the configuration and restart NetworkManager.
```bash
sudo sysctl -w net.ipv4.ip_forward=1
sudo sysctl -p /etc/sysctl.conf
sudo systemctl restart NetworkManager
```
