RPI Image not connecting to WLAN
Hello, I am currently trying to setup Repetier Server with the new RPI image. I loaded the image onto an 8gb card, and placed it in my RPI 3. HDMI connected screens see the frontend, but I cannot interact with it. Also, attempting to connect via WLAN does not work. I tried attaching an external wifi module via USB, and it still has no connection for WLAN. Can you think of anything causing this, or is there a way to manually setup network connections via text editors, rather than the frontend?
