Looking to buy a wireless router..help!!

[Cyberboy109]

I have moved in with my Girlfriend and she is with post office for broadband...and the router wifi signal is terrible its pointless.

So looking into a wifi router I can plug into the post office hub its just for mobile devices, and tv streaming.
I have about £100 to spend


*we will be changing provider and to fibre

A Tp Link Archer C7,AsusRT-N66U, or a netgear AC1750. Seem to be the most popular for that price range.
