@Drea that is very unusual while you may get a few days of loss of connection due to overnight maintenance between midnight and 5am which is unfortunately a faxt of life like overnight road works.once the work is complete your service will return to normal.
However if literally every night for weeks you lose signal from 11pm to 6am it sounds like there is some kind of external control on you service like a time clock. By default no Sky hub has a time clock built-in but you can pay extra for Sky's WiFiMax bundle that includes Parental Controls shich the account holder controls not Sky. It is therefore difficult to explain why you have this issue.
