No it doesn't. Concrete floor and structural walls, rest is some form of bricks, typical European modern building (Switzerland), absolutely good enough wifi signal in all rooms, on 2 storeys, no repeater or anyhow enhancing the reach. Router is in a far corner of whole structure, as far as possible from being in the center. This is just basic phone company wifi router provided to us. It works well with all laptops, at least 20 different phones based on various visitors, desktop with some basic external wifi antenna (this one is farthest, 11m and 1 wall). But we don't have any 'smart' crap in our house, no zigby stuff, no fridges with tablets in front or similar. Interesting how many downvotes this triggered on all of my comments on HN that could still be downvoted.
