Wifi and hotspot not working

[Android Central Question]

On my lenovo vibe c A2020a40 my wifi and hotspot isn't turning on. This problem first occured a month ago.Then all i had to do was restart if this problem occured.But restarting didn't work anymore after a week.I even reinstalled the firmware but still it wasn't solved. I thought it was gone bad permanently but today i restarted my phone and the wifi is working again. I'm pretty sure that the next restart will cause the problem again.Any help on what can i do to solve it?
