I don't know if this is the right place to ask about this, so please move it if needed.
Our house has had the Tecnicolour 582n for about 3 years now I think since we joined plusnet on non-fibre broadband using the openreach modem box for the fibre connection and we have been discussing recently about seeing if we can possibly upgrade our router to the hub one seeing as our current router is getting pretty old. We have also started seeing wireless signal issues at areas around the house and believe this could be because of the routers age,
Is it possible to upgrade at any time? Or would we have to wait until our contract is up? We would be willing to pay for it if necessary.
