You can wirelessly share your Wi-Fi or wired internet connection with other devices by turning a PC into a hotspot.
Just open Windows 10's settings and head to Network & Internet > Mobile Hotspot. The "Share my Internet connection from" box should default to whatever network adapter is currently connected to the internet, though if you're currently connected over Ethernet and Wi-Fi, you can choose which connection you want to share through this box.
Choose whether you want to share over Wi-Fi or Bluetooth—chances are you want to share over Wi-Fi—and click the "Edit" button to create a name and password for your new network. When you're ready, flip the Mobile Hotspot switch to the on the position at the top of the settings, and use your newly created credentials to log in from your phone or another device.
You may experience slower internet while doing this, due to the inefficiencies of Wi-Fi sharing. Still, it's better than nothing, especially when you're in a bind.
