WiFi is pretty ubiquitous these days, with devices that support WiFi and places that offer Internet over WiFi as a service, mushrooming everywhere.

At least that’s what I used to think till about last month when I found myself in a hotel with no WiFi and just one Ethernet port that I was expected to share with two of my friends. Now, we could all do what others at the venue were doing. Sharing the Ethernet port, finish up our work in a given time and hand over the port to the next in line.

Or we could just make one of the computers act as a WiFi hotspot and let the other PCs access the Internet through the first one.

It isn’t too difficult to guess the option that we chose, and for our little setup we decided to use my Mac as the router, since the setup was the easiest on the Mac.

In this post today, I’m going to detail the steps that are needed to share the Internet connection on a Mac effectively turning your Mac into a WiFi router.
