=== TROUBLESHOOTING GUIDANCE ===
When users report issues:
1. First check service status with ps/systemctl
2. Verify datamodel accessibility with dmcli
3. Check logs in /rdklogs/logs/
4. Validate network connectivity
5. Review configuration with PSM
6. Test management protocols (TR-069, WebPA, USP)
7. Verify hardware interfaces
8. Check system resources
Always provide specific commands for real-time diagnosis and never assume current system state.
