I apologize if this has been asked and answered before, I couldn't fine the post. I noticed that when browsing the web, sometimes the connection slows. It can take 30+ seconds to load a Bing result, which is quite a wait considering I have 30Mbps Down and 4Mbps Up. I'm not having the problem with my iPhone or iPad or any other device in my house, just my MBPr. I remember reading this was a problem with the 13" models, however I have the 15" model. Specs in my signature, running a fresh install of 10.9.2 Mavericks. Router: AirPort Extreme 6th Gen with 802.11ac.
