Idk about anyone else, but the only public place i'm in long enough to even test the issue is hotels. But I've not had it occur there... YET. 

Seems to only happen at home & work. Which are completely different types of modems/routers.

Does the issue occur with the device in safe mode?

@SamsungLarryK haven't tried, but I can be in middle of USING wifi (watching youtube or a movie etc) and it'll suddenly crash on me. 

I've even just left it in airplane mode with wifi on to force phone to use wifi only & not even attempt to switch or turn on data & it does it. 

There's no particular timing either. I've had it happen overnights, 4am, 10pm etc... I could be using it, or it's just sitting next to me & i'll pick it up to do something & the wifi crashed on it. And yet anything else on wifi works perfect, so obviously not the signal.

Hey, give this a try. It can show which apps are causing battery issues, viruses, malware or app crashes.

This seems to work for me, hope it will hold on!

Type  *#9900#   in your keypad scroll down to WLAN FIRMWARE DUMP MODE and turn it off than click on WLAN ADVANCED DEBUG and click on DISCONNECTION SYSDUMP and press OK.

 

When you did this scroll up to DELETE DUMPSTATE and press ok. Then click on exit at the bottom.

 

When you done all of this type *#2663# in your Keypad and press on REFRESH WIFI VERSION.
