We are due to get fibre installed fairly soon. We are also thinking of upgrading our 5 year old router to dual band, 801.11ac etc. Are there only specific routers that may be used with a fibre connection? I was looking at reviews of the TP Link AC1750 D7, earlier and came across one review that stated it is not "fibre ready". What's the story with that? What do I need to look out for when researching a "fibre ready" router?

Thanks for any advice.  :)
