Gene, I am using a USB-c 240gb SSD drive. I am booting from the SSD drive.
I have the 7i76e connected to the onboard ethernet and it is the only thing connect to it. I have the onboard wireless setup but I generally don’t use internet from the RPi4. I have a USB3 to Ethernet dongle. Maybe I need to disconnect the wireless and figure out how to enable internet through the dongle?
