    My router can put out a 2.4 and a 5GHz wifi.

    iPhone connects fine to 2.4GHz (n) network with full signal but takes longer to see and connect to 5GHz (ac) network, shows lower signal strength and disconnects every once in a while.

    Any idea how to fix this?

    Have only had the phone for a week or so, but I had this issue with my 5S too.

    In no specific order, things I would try...

    Reset network settings on iPhone.

    Reboot router.

    Change radio channel on router.

    Do a speed test on 2.4 and 5. If the difference is nominal, just use 2.4.

    I've tried these with the 5S too but to no avail.

    Speedtest shows slightly longer ping on slower network.

    But to my understanding 5GHz ac is supposed to be "cleaner" plus it's a faster wifi for iTunes to sync with my iPhone, no?

    5ghz doesn't have the same range as 2.4ghz and is usually a weaker signal unless you're right by the router.

    All my apple devices prefer the faster 5GHZ network, but they take much longer to connect to it. They usually hop on my backup 2.4ghz network. My MacBook doesn't do this though, but of course, it has a stronger antenna

    Gotta be in it to win it
    I have a net gear r8000; it's a beast of a router with 3 radios. My Idevices prefer the 2.4 band and what i do is have the one 5ghz ssid enabled, the other bands forgotten.
