For a month, I have been having a severe packet loss that comes in intervals on any connection. All applications are working fine except the ones that require needed constant connection, such as Online Games and Video Calls. Called the hotline and they cannot seem to see the problem from their side. I have also tried changing to a new router in suspect of the old one being broken. The experience is horrible. Another household internet contract (same building) I am using is working fine, except for mine. Is there anything I can do about this issue?
