Use your smartphone as a router
How to Connect Internet from Mobile to PC or Laptop via Hotspot
WiFi is almost as basic a necessity as electricity: you only notice it when it doesn’t work, and then panic sets in.
If you are stuck in such a situation, probably because the WiFi connection keeps dropping, no device can connect, or the network disappears altogether, don’t worry. There are several ways to fix these issues.
One of the fastest ways is to connect your computer to a mobile hotspot like your smartphone and share the internet connection. In this way, your phone acts as a router by creating a hotspot, although you are using your mobile data in the process.
