Ok, so I have the new Macbook Air and a new Time Capsule and I am currently running on Mavericks. My Wifi speeds seem slow compared to my 2011 Macbook Air on the (N) Wireless. Here is the speed test and here is the Wifi on the Macbook Should I have an exclusive 5GHz network? is there some setting I need to change in the Airport Utility? I don't understand why things are going slow?
