The way my house is the router is on the ground floor (Directly 1 floor below my PC.) I used to get max wifi and around 60 mbps download speed and now I only get 2-3 bars of wifi with around 20mbps. This has also shot my ping in games from 15-20 up to 50+. Sometimes it shoots up to 300+ for no reason randomly. Nothing has changed and I don't know why it is doing this.
