Free WiFi Hotspot Software App for Windows Computers - Connectify

With the Linksys Smart WiFi App, you can set up a guest network for non-family members, to prevent access to your main network and the home devices connected to it. While your guests may not intentionally compromise your WiFi, creating a separate network also serves as a layer of protection if their devices were to be infected with malware. The guest network should also have a separate SSID and password that you change periodically. | Linksys
