Sounds like the Hub may not have been activated properly on your account.
Try a pin hole reset of the Hub as below. While its doing it, call the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. on any faults and tells you of more local issues down to postcode level.
If it doesnt come to life after the reset, call the equipment activation number on - 0800 953 9500 (option 3) – you will need the serial number/MAC address off the barcode sticker and also your account number, get them to checkand reactivate it.

Do a Hub “pinhole reset” - first make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub (leave the coax connected), and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly for at least 60 (a timed sixty) seconds, release the pin, leave for 5’ to stabilise - dont manually switch it off at any time. Passwords will reset to those on the sticker. See if that sorts it. If not try the reset one last time and hold pin longer.
