Too much connection loss

Hi ​@serkan caliskan, I'm sorry to hear you're facing problems with your connection 😕

Have you tried disconnecting the ONT, like ​@Ik_Combineer suggested? If this makes no difference, please contact our customer service for further assistance, so my colleague will be able to test and measure things 'live' with you on the phone!
You can easily make an appointment via our digitale assistent. Whether this is as soon as possible or at a later time that suits you best, both are possible.
