Hi @andreaskoltai
Welcome to the Community!
Using your community details to pull up your account, I was able to run tests and confirm that your modem is not being detected at all.
If you have already tested a different power outlet, we are indeed looking at a nonfunctioning modem since the lights are off. Based on our records, your modem is already out of warranty. We will send you a PM providing options on how you can get a modem from us. Please check your inbox and reply with your selected option.
Regards,
