Hello Macskapjti
We're sorry to hear of the broadband issues experienced, we can understand the frustration this is causing and you raising this via the forums.
From checking the speeds to the hub they are averaging over 1140mbs download and 50mbs upload, there have been numerous disconnections and the hub is currently showing as offline. Is this the case?
From looking at the connection and equipment there does seem to be some power issues with one of the upstream channels which may be causing some issues. I will send you a Private Message to get some more details form you to get this looked into further.
