 2. En mode AP, l'adresse est toujours `192.168.4.1`
 3. En mode Station, trouvez l'IP dans les logs du moniteur série
 4. Désactivez le cache du navigateur (Ctrl+F5)
+5. En réseau entreprise (PEAP), un filtrage « client isolation » peut bloquer ping/HTTP entre clients WiFi
+6. Utilisez l'AP de secours `ESP32-Webapp-setup` (ou `<hostname>-setup`) avec l'IP `192.168.4.1`
+
+### Diagnostic rapide réseau (2 minutes)
+
+1. Ouvrez le moniteur série et vérifiez `Serveur web démarré sur le port 80`
+2. Depuis votre PC, testez l'endpoint de santé:
+  - en STA: `curl -v http://<ip_sta>/api/health`
+  - en AP de secours: `curl -v http://192.168.4.1/api/health`
+3. Vérifiez les logs série:
+  - si vous voyez `HTTP GET /api/health depuis ...`, le trafic arrive bien
+  - si rien n'apparaît, le réseau filtre la communication vers l'ESP32
