What a weird thing to be concerned about.
This is like writing an article that a Macbook Air can't play the latest Call of Duty Game

Your analogy is also a poor one because it's well known in the "thin and light" class of laptop that all of them use CPU integrated/low TDP graphics, designed first and foremost for 2D desktop performance (plus H264+HEVC encode and decode acceleration), and none of them are particularly capable of playing intensive 3D games.
If you want to game at 1080p and anything close to 60Hz with high texture details it's a fact that no matter what brand/model of laptop you buy, you're going to be buying something thicker, a bit heavier, with a discrete GPU on the PCI-E bus.
Fact is that laptops in the $1300+ class were shipping with 802.11ac 3x3 capable interfaces seven years ago. The wifi performance of a mid-2014 macbook pro will run circles around this thing.
What a weird detail to make so much noise about.
Most WiFi products these days never go to an RF lab for fine tuning.
If that is something that you need, then you obviously are going to select hardware for it, just like you would for gaming.
