Hello,
the DIY mentions a USB adapter for Wi-Fi as the RPi 1 for example didn't have an on-board adapter. I do not have an RPi3, but after a quick search I think the BCM43438 chip can operate in AP mode and therefore should work.
Installation therefore should be as described, using the image for the RPi3. Did you follow the guide step-by-step?A common issue is that a step gets left out by mistake and works in most cases for the second try.
If you have tried again and it still doesn't work, please report back. Also, giving additional information might help troubleshooting.
