New Rpi 4 ethernet port not working

Tue Oct 20, 2020 8:31 pm

This Rpi-4 was purchased on order: 2381375-6818470952

From day one there has been a problem with the ethernet port. I've tried different cables, switch ports, etc. without luck.
ifconfig says the port is up, but no ip address.

Running 2020-08-20-raspios-buster-armhf-full.img with everything updated (sudo apt update; sudo apt full-upgrade)

dmesg shows and a couple of issues at boot time, then shows eth0 bouncing up and down every few seconds.

Looks like a bad board to me. Let me know if there is anything else needed.

Apparently it tries to work...

Code: Select all

 TX packets 2695  bytes 419578 (409.7 KiB)
I’d bring the Pi to another network. Use their cables.

I suspect it is trying unsuccessfully to get an IP address. I removed the ethernet cable from a different (and functioning) pi-4 and plugged it into this unit. The other unit is now reconnected to that cable and functioning normally. I also tried other cables and ports on the switch, to no avail.

It is unlikely but try swapping the power supply + cable as well. If that doesn't help then it does look like the Pi is faulty and you need to contact whoever sold it to you for a replacement.
