Installing new wires in room with hardwood floors

It's one reason that people prefer wireless, but as you pointed out, that leads to performance compromises.   My one small hole in the hardwood floor, out of site, works for me, but the individual characteristics of every home are different.  I had wired the house first myself and while everything worked the results did not meet SAF.  I then asked an IT Pro that was helping with an unrelated issue and his solution at first made me gulp about assaulting the floor but it was the right all.  You may wish for a consult from someone who has done a lot of IT connections.

It's a very simple job for a pro to put into the wall. You'll be paying a lot for that floor box alone if you go that route.

I suggest you try the inwall yourself if you're handy. The hardest part is knowing exactly where to drill up from the basement.  Just cut out the box location in the wall and after you drill the hole ip, you'll see the cables right there because the box is low to the ground on the wall. 

I'll add this. If you don't want to do that, you can fun the cables and leave them under the location you want them at the wall. Then a pro will just have to drill the hole as mentioned and cut out the hole in the wall and connect. It would be cheaper that way.

20-30 minute job. Good luck.

 You can "run" the cables...
