iPhone 5 always has wifi issues at home

I have been having this issue on several different iPhone 5 devices and two different Airport Extreme (5th and now 6th gen).

I constantly have to go into the settigns and set the iPhone into airplane mode and toggle it back off. It's the same as me turning off wifi and then turning it back on. This ALWAYS fixes the issue until it happens again. This isn't a range issue, I can be standing right next to the router and still it won't load anything until I "reset" the connection. It will work for some time until it does it again. Turn wifi off, back on and I'm back again. You get the picture.

Here's the thing. I have 4 iPads, 2 laptops and other wifi devices in the home that have zero issues like this. It's only with the iPhone 5's in the household. At work, I don't experience this issue. I'm thinking maybe there's something going on between the iPhone 5's and the Airport Extreme routers? Is there any documented information on this? Anyone else experiencing this and how can I resolve it besides just hoping this issue is fixed with the next iPhone? I remember my iPhone 4S was doing something similar. I thing it all started with iOS 6.
