- You have a laptop or PC with WiFi: You can create a local network from your computer, allowing other devices to connect.
- If your computer doesn't have WiFi: Purchase a WiFi USB (cheap and easy to install) to provide your PC with transmitter and receiver functions.
Native Options in Windows: Mobile Hotspot
Windows 10 and Windows 11 include the Mobile Hotspot feature, which allows you to easily share your connection without additional software:
- Click on the icon Red on the taskbar and select “Mobile Hotspot.”
- Set the network name (SSID) and password as you prefer, ensuring the use of a secure key (WPA2).
- Activate the function: your PC will act as a WiFi router and allow the connection of up to 10 devices.
- From your other devices, search for the newly created Wi-Fi network and connect by entering the defined password.
Using third-party programs: mHotSpot and similar
If your operating system does not include this feature or you need advanced options, free applications such as mHotSpot allow you to easily create a WiFi hotspot:
- Download and install mHotSpot. Reject additional software during installation.
- Set the network name (hotspot name)a whirlpool bath, secure password and select the Internet source (WiFi, LAN or Ethernet).
