Wi-Fi connecting and disconnecting

Can a malware disconnect you from your Wi-Fi? As I have learned that virus doesn't exist in mobile devices, all that's left is a type of malware. But my device isn't showing any signs that it has a malware like what it should be. I've also tried checking if there's a timer active, the "always keep my Wi-Fi on", and all of them are right. So, if not, then what is causing my device to disconnect?

 

Not yet. I'm gonna have to try it. So it is not because of a malware? Wi-Fi isn't disconnecting anymore, but I'm still concerned if this is a malware. If it is, then more problems will occur.

 

Right! Thanks. Just being paranoid here. Thanks again.
