I *think* your wiring is the wrong way round, I can't remember the layout for bottom up. Try getting just one board to work first. Plug the Pi's cable into the right header of the top board [where the other cable currently is]. If that doesn't work, try the right header on the board below.
Tried to just run one blade and still same issue... Here is both the config page and my gateway details...
Try to replace the DNS not the router but the DNS of your ISP
Your wiring are OK, allways connection to RPI on the right, on the top or on the bottom same thing RPI on the right.
Tried to replace DNS and no success...
When i turn it on the fans start up, so i know there is power feeding into the garden. Able to access the config page so it's online. I did try and ping from my RPI and it didn't work. There is no internet connect that my RPI is picking up, though i'm not sure if that matters since i can access my status page on the cgminer....
not sure why this still won't work.
