I just flashed an SD card with the 64 bit rpi 4 image. I connected it to the same network where I’ve been running a Rpi3 without problem.
This Rpi4 does not show up on the network, it is as if it does not get a connection over ethernet. I removed the Rpi4 and put the Rpi3 back and it starts up like usual.
Do I need different network settings for the Rpi4 or where should I start checking for errors? I do not have such a mini hdm adapter so I can not get a picture on a monitor.
The ledsen behind the ethernet ports light up a few seconds after I plug in the power to the rpi 4.
