Now I can't connect with PuTTY anymore. (Error: Connection timed out.). Connection should be possible, because the LEDs on the ports are blinking. I suspect that the IOT now has an IP adress I don't know. How can I access my IOT again? If possible, I don't want to rebuild everything from scratch... Edit: For future references: Using wireshark to detect the IP adress seems the way to go.

You can have serial debug access via putty to your IOT. Another possibility is to use e.g PRONETA. With this tool you can check your network and it displays all IP addresses available. Best regards!
