Modem Crashing upon Wifi no signal topic

Hello, any assistance would be great here! I'd like to avoid doing a full complete reinstall but, if its necessary and if thats what it comes down to, so be it. Here's whats happening. It seems every time i switch my WiFi off or it loses WiFi signal, the radio completely crashes and won't connect to mobile network anymore. I have to do a reboot and upon reboot all works fine. Very frustrating! I've tried reinstalling the modem and trying different modems to no avail. I'm at a loss as its rather frustrating a waste of battery having to reboot the phone. If i never use WiFi and let it stay on mobile network all the time, i never have the issue. Or if i stay in WiFi all the time, no issue. Anyone else ever have this issue?

Once upon a time there was an Exynos variant called U in Lollipop Land topic

Wanna know the ending?
