I was going to make a topic about this, but I am a junior member, so I can't LOL
I recommend everybody to switch from wireless to wired. It is much better. It is not affected by other electronics, and the connection is faster and much more stable.
The main issue I had was the fact the router was in my basement and my systems are on the top floor. I felt it would be too much hasle to wire the systems, but in fact it is really easy.
Just buy this at amazon:

Very cheap, 35 bucks. You basically connect this to any power outlet. The first one you connect close to the router/modem via ethernet cable. The other one you put on the power outlet that is close to your systems. The beauty is that it can be several feet away, different floors and still works fine.
THen I used this switcher:

I connected this switcher to the other powerline device. Then I connected all my systems (wii U, xbox one and ps4) via ethernet cable. Now all of them have wired connections and that cost me 45 bucks. The speeds are basically the same if you have connected directly to your modem. Maybe a 10% loss at most, but In my case it was almost identical.
Now I don't care about updates messing up with the wifi download speeds.
Just do that guys
