This feature will not work with Canon cameras.
This feature works only if the pc wifi is connected to the device wifi using pc wifi network connection.
This solution use a cheap router TP-Link MR3040 with a custom firmware. The firmware was adapted by Hubai Zoltan so all credit goes to him.

If you change router firmware, you will lose router original functionality and warranty; so think twice, act once.
After firmware update only things remain to connect camera to router and your pc/laptop/tablet to router using WiFi connection.An IP dialog will show up where you can set the server IP number, which in most cases will be 192.168.1.1
