Supplied router - wirelless capability?

[#1]

I'm looking to upgrade to fibre. I've presently got a NetGear router in my upstairs study plugged in to my desktop PC, and our two laptops access it from downstairs.
The upgrade to fibre package says I will be sent a PlusNet router and that other routers will not work with fibre.
But will the supplied router enable wireless connection for my two downstairs laptops?

The PN supplied router is wireless. However, I found that the wireless was weak & my wireless speeds were much lower than when connected wired. I bought myself a dual band Asus RT-N56U which is much better.

Thanks, that confirms my suspicion they will only supply an 'entry level' one, shall we say...
