All these times, ever since I’ve had my smart phone, I don’t turn off my wifi. It automatically connects to existing wifi networks that I have previously setup on my phone. This is a convenient way to stay connected automatically to known networks. It also helps if you don’t have much data for your mobile phone’s plan. The phone would use wifi if there is a connection. This is all fine, except if you have a wifi network setup already, and you happen to drive by that network, your phone would automatically try to connect to it. The annoying part is, once you drive a little further away from that location, the wifi signal would drop and the connection would drop. The phone would try to switch back to the mobile phone’s network for data. So, whatever you were doing with the phone whether listening to music or on a FaceTime call, the connection may lag or cutoff for a bit until the connection is stable again.

There are times when you want to share what you’re working on with others. The problem is that the site is running locally on your machine, and it’s only accessible in your local network. You can open up the firewall and configure port forwrading in the router to forward the traffic to your machine and give your publicly accessible IP to your collaborators. But, that’s a lot to get started and get things working, not to mention setting up SSL certificate, among other things.
