How to share wifi from mobile to laptop?

This is quite simple. On your mobile, navigate to your Settings. You will want to find the option for "Mobile Hotspot" or "Tethering."

Enable this feature. You can then set a network name and a password. On your laptop, search for available Wi-Fi networks as you normally would. Your phone’s network will appear on the list. Select it, enter the password you created, and voilà! You are connected. It is a very reliable method.
