S7 goes crazy when wifi turned on

[Bobhowr2005]

When i turn on wifi my phone will slow way down and freeze. I tried restarting and it took forever. It had blue status light and tiny blue dot in middle of screen. Then just a bit ago my phone was automatically restarting. However wifi was turned off.
