Why does My Wifi Keep Disconnecting?

These are the possible reasons why a laptop keeps disconnecting:

1) The laptop is not connected to an external power source: First thing you need to do is: Connect the laptop to an external power supply and see if that helps. 

This issue may arise when your laptop’s battery percentage level gets too low.

2) The router is not working: Connect another device to the wifi, like a smartphone or tablet, and see if it can access the Internet via the router. 

If the other device connects to the Internet, it means that your router is working fine and you should focus on your laptop’s wifi settings.

3) The wifi card in your laptop does not work properly: This is a big possibility.
