    No. My 6S is at that release and it works on 5Ghz same as before update. Have you tried turning Wi-Fi off and back on, or Airplane mode on and then off? Sometimes that seems to bump something.

    I’m having similar issue – iPhone 7+ on 12.2.6. Works fine when connected to 2.4GHz channel, but seems to having problems pulling data over 5GHz channel; even though it connects and has strong signal. Router seems fine.
