Welcome to the TalkTalk Community.
The out of the box setting for the Wi-fi Hub is to request an update from the TalkTalk update server once every 48 hours. If you leave the router powered 24/7 and connected to the incoming line then the Hub will update itself.
I see your Community profile is 50% or more completed so just double check to ensure the landline 'phone number is there as that's how TalkTalk will identify your service account. They can then check from Monday onwards to make sure the Hub has done its stuff and if not can push an update for you.
