Hi @Anonymous User
I doubt you will get an answer here, where you are better off either giving the NowTV Broadband Team a call or contactIng their Live Chat service for the answer.
Open the link page below and click the most appropriate help topic and once on the final stage of the process scroll down to the bottom of your screen page and click on the drop down arrow below Get in Touch to contact NowTV.

Bit of a long shot in the meantime where you could try switching the power off to the Hub Router for a minute to see if it re triggers the internet coming back on, but i doubt it will work.
