Just updated my 6S+ to 9.2.1 yesterday. All looked good but have run into an annoying wifi issue. When I awake the phone from sleep, it stays locked onto LTE. If I go into settings > wifi it shows wifi is on and linked to either my 2.4 or 5 ghz signal. I either have to turn wifi off/on or select the alternate wifi signal for it to reconnect. Rebooted, hard rebooted, and CP don't help. Don't want to restore or setup as new - work phone. Any thoughts or ideas? Something I am missing? Thx in adance.
