March update destroys wifi

[AC Question]

Ever since the latest forced update last week, my S7 will not stay connected to my Wi-Fi for more than a minute or so! When it is connected, it bogs down my speed something awful! I have to remember to turn off mobile data because when this thing kicks off the Wi-Fi mobile data takes over and I don't have unlimited data! All other devices on wifi are fine as long as the phone is off. Help!

This worked for me. You'll have to add WiFi connections again and pair any Bluetooth devices you use.
