I have this same one..

"Canaan by default set the PI with a static address at 192.168.0.100. "   So you need to set your laptop IP to 192.168.0.99, mask 255.255.255.0, gateway 192.168.0.100, then plug directly into the Pi.  You should then be able to open a browser on your laptop and point it at http://192.168.0.100.

From there
"if reach you controller’s web interface at http://192.168.0.100, then on the “General Setup” tab, change the “Protocol” from “Static address” to “DHCP client”. Then click “Save & Apply” and wait 30 seconds. "

Now your Pi should be on your network
