I have an iPad3 64GB WiFi only that I replaced with a Pro 9.7 128GB WiFi only. In my bedroom the iPad3 worked just as well on the 2.4 and 5Ghz band. Watching Showtime Go on it never stopped or even stuttered on it. I usually used the 5Ghz band as it was 'faster' My ISP speed is 100Mbps and on both band the iPad3 got ~40Mbps due mostly to the antenna's. The Pro on the other hand has a problem with the 5Ghz band. It drops constantly, and usually will NOT reconnect. I have to switch to the 2.4Ghz band and then back to the 5Ghz to reconnect. Both bands on speed test get ~100Mbps. I do have an AC router and the Pro can do that speed. So I have 2 questions. Why is the Pro having a problem staying connected to the 5Ghz band when the iPad3 has no problems in the same location? Is there a way to restrict the Pro to N speed (assuming that might help if AC speed doesn't have the range?)?
