Question about Nighthawk gaming router

Hey guys, I have a question and wasn’t sure who to ask.

Basically I just moved and I’m unable to hardwire my Xbox . I’m staying in a basement and the router is on the first floor. After testing, the connection is supposed to be good but I experience lag quite often when gaming. I was considering buying the Nighthawk pro for gaming to help combat this. What I was wondering was

-is this a good method to help with lag -I’m only one floor down directly beneath the router/modem, would the distance be a problem since I can’t hardwire

Thank you.
