Apologies if you've been asked this before but I'm just trying to ensure you're not wasting money unnecessarily.
How do you know your router is at fault?
I don't which is why I have unplugged the cheapie UPS unit, just in case that is causing the router to shut down. Unfortunately that could take days before I will really know.
I have since found that that our area will be going full fibre sometime next year so probably best to put everything on hold. It was only by chance I found out from Openreach as I did not think we would ever get FTTP for many years living in a rural village.
Not sure if you can use a FTTC modem/ router for FTTP if we do get FTTP. Do they make routers that can be used for either FTTC or FTTP?
