Hi! I'm new to the Mac family with my first MacBook Pro with a late 2016 15" model. So far everything is great, but I noticed one major issue. My wifi speeds are not constant. Whenever I would normally be able to download something very fast (e.g. from Google Drive or Steam), I get download figures like in the following picture I attached. What happens is that it goes to full speed of my connection, but then drops to anything between 100-400 KB/s, then goes back up to full speed and down again. I tested this on different wifi networks and also compared the speeds to my old Windows machine - no spikes there. So it's definitely the MacBook or OS X. Any ideas?
