Hi there mrod,
Did you setup the Pi from scratch, or use one of the provided Raspbian images? I recommend starting with the latest pre-built Raspbian image. The latest release has been tested on a Raspberry Pi 3 without issue.
- Follow the instructions for flashing the SD card, here.
- Insert the card into the rPi
- Power on the rPi
- Look for a network called
Pi3-AP on your computer. It can take a moment for the network to become visible. If you still don't see it, try refreshing your list of visible networks.
If you still don't see the network it is possible the installed image was corrupted or there is a problem with your Pi. Remember that pulling the power from a Pi that has not been shutdown can corrupt the image on the SD card. If that is the issue, a fresh install of the image should fix the problem. Just be sure not to pull power before connecting, expanding the file system and shutting down the Pi.
If you cannot see the network or ssh into the Pi, you can try connecting to the Pi using a monitor and keyboard in order to debug the issue.
