I live in metro Detroit and we just got AT&T LTE a couple weeks ago. I live in an area where I have 5 bars of LTE. My iPhone 5 can maintain LTE connectivity with no problem; signal strength is not an issue. But my iPad will drop it after a few minutes or so and go back to 4g, even when the iPhone 5 is still on LTE. I've reset network settings and it makes no difference. If I turn airplane mode on then off or cellular data or LTE, it will connect back to LTE right away but drops it again after a few seconds or minutes. I've looked around and can't tell if this is a common issue or if there is a fix. Any ideas?
