## What this does
LAN discovery lists devices and advertised services on the Wi-Fi network GhostESP is currently connected to.
## Before you start
- Connect GhostESP to the network with [Connect to a Wi-Fi Network](/v2.1/wifi/connect/).
- Only scan networks you own or have explicit permission to test.
## On-device steps
- Open Menu → WiFi → Scanning while GhostESP is connected.
- Choose Scan LAN Devices.
- Review the discovered devices and services.
## CLI steps
- Run scanlocal to discover devices and services.
- Run scanarp to list active devices by IP address.
## Expected result
GhostESP lists available hostnames, service types, ports, or IP addresses. Results depend on the devices that respond and the network’s isolation settings.
## Troubleshooting
- No devices appear: Confirm GhostESP is connected to the intended network and that client isolation is not enabled.
- Only some devices appear: Retry after devices are active; not every device advertises services or responds to discovery requests.
- The connection drops: Reconnect GhostESP, then repeat the discovery scan.
