Road warriors who travel all the time know the problem. Your hotel room offers free WiFi, but it’s only for a single computer or you have to pay extra. Or you have a 3G dongle delivering broadband to your laptop, but you need to access it from your phone or another device to get some task done. Basically there are times when you need the convenience of logging on to a WiFi network access point, quickly and easily.

MyPublicWiFi is a freeware program that installs onto your laptop and turns it into a wireless hotspot, so you can share the connection with other devices or computers. The software comes with all the security you need to prevent abuse, including the ability to log destination URLs and to bar P2P operations like file sharing.

As well as helping you get your family and friends online easily (no need to hunt around for the router password when friends visit and want to log on) we can see it being very useful for small cafes and other consumer businesses who want to offer a cheap and controllable WiFi service for their customers. The service can be switched off with one button, and works with Windows computers.
