Much as they've made other mistakes, lingering WiFi issues are not necessarily Apple's fault. There are all sorts of things that can go wrong. For example, I've had routers be unstable with some particular devices because of specific encryption settings. Ironically, I learned about that chipset problem while I was getting ready to throw dd-wrt on the offending router in frustration. I've had access points give super-slow connections to new devices until the AP was rebooted. And on and on. WiFi works most of the time, but when it doesn't it usually isn't easy to figure out what (or even where) the problem really is.
