In Windows you can turn your PC into a wireless hotspot, thus allowing you to share its wireless or wired Internet connection with other wireless devices. But to you set it up depends on the version of Windows you are running. Here’s how it just works.
Turn Your PC Into a Wi-Fi Hotspot
If you can not get the in-built Windows Wi-Fi hotspot working, you must try Connectify Hotspot instead. Connectify is a completely foolproof Wi-Fi hotspot which has a tons of options and a clean interface.
Connectify Hotspot is really great if you are at a hotel which charges per device, or if you are on a plane and you connect your laptop but don’t want to pay more to connect your phone. If you pay for the Pro version you can even use your PC as a Wi-Fi repeater or a wired router, or share a tethered connection off your phone
It’s really more of a power user tool, but if you’re looking for a good solution, Hotspot is free to try out, and the basic version is free with some limitations.
Share a Wired or Wireless Internet Connection in Windows 10
On the Network & Internet page, on the left-hand side, click “Mobile hotspot.”
On the right-hand side, turn on the “Share my Internet connection with other devices” switch. If you want something other than the default network name and password, click the “Edit” button.
In the Edit window, type whatever network name and password you want to use and then click “OK.”
And that’s all you really have to do in Windows 10. It’s one of the best new features of the Windows 10 Anniversary Update, even though it rolled out with relatively little fanfare.
