Can you describe the exact procedure? I also started wtfpairing on my laptop, but could not get the camera to connect :-o
Sure, hope this will help. On camera it's pretty straightforward - go to wifi menu, select wifi function->Remote control (EOS Utility) and follow on screen information to connect to your router until you see the message "start pairing devices". Dont click OK yet!
Then on PC go to C:\Program Files (x86)\Canon\EOS Utility\WFTPairing\ (or different if you installed somewhere else ofc), right click on WFT FirewallSettings, select "run as administrator". Next in the same way run as administrator WFTPairing. Now click OK in the camera to start pairing and in that program you should see after a few seconds your camera. If you don't keep the WFTPairing window active and on camera press Cancel and OK to start pairing once again.
At least it worked for me just now (I did the procedure writing it down).
Also I first connect to camera with the WFTPairing, and after that I start EOS Utility (I keep EOS Utility not running during pairing).
//EDIT:
Damn, I've found out that I'm unable (yet) to connect to the PC using the saved settings, it seems like I need to go through the whole procedure of creating settings set to connect to the PC, what a disaster from Canon...
