My WIFI Router has your laptop (or wireless-capable desktop) emulate a network router complete with most features. This lets you share Internet connected devices and a few other things too with anyone who connects. It also has basic security features and more than a few other nice frills!
Fast and Fearless
My WIFI Router has some surprisingly strong features for such a simple piece of software many stemming from it creating a fully-fledged network router. For example you and those on the network you create can all watch videos via My Videos and individually control your playback: perfect for long road trips with laptops but no Internet access. It's even possible to move files to and fro if that's your pleasure. Even without Internet the app is useful but it's great for sharing your 4G Internet with others for example. Just keep one thing in mind: leaving an open router is risky for security reasons and My WIFI Router doesn't provide a ton of high-grade security options. At least there's a blacklist.
A Basic Choice
Overall My WIFI Router is best for those who just want to use their laptop to share Internet and other things and don't have much cause to worry about interlopers. It's easy to use and has a great video sharing feature so long as security is not a concern (like the road trip example above) this is a great routerising option.
