Dell Inspiron 5575 Wifi issuses

Hello! I recently bought my Dell laptop (Windows 10) about 4 days ago. The first day my WiFi connection was perfectly fine. But after that it keeps crashing. And it only happens when I connect my laptop to my WiFi. Everyone else's devices work fine but when I connect it just crashes. 

The WiFi status shows it's connected but nothing loads for me and gives me "Unable to connect" or "No internet". 

My network adapter is Qualcomm QCA9377. I've tried updating both the driver and my laptop but still nothing!
