I succesfully flashed raspian for robots (2018.06.27) to my sd card with etcher. Inserted my sd card in my raspberrypi/grovepi, connected ethernet to my laptop and power supply. First 30 secconds I have a red led and blinking green red. Afterwards only red led stays on, no connection made however when i try dex.local. Tried to re-install the image several times but without succes.
Any suggestions for solving this problem? Thanks
