I've been breaking my head on this one for days. I bought a Raspberry Pi 4 (the 4GB version) and installed the latest LibreELEC-RPi4.arm-9.1.502.img on it.
After booting up, everything works fine except the ethernet port. WiFi works, but there is absolutely no activity on the ethernet port. The lights are not flashing and the ethernet network is not showing up in the network settings in LibreElec. The list is just empty when I disable WiFi and enable Ethernet. (advanced IP scanner can't find it on my network either). I made sure the cable and the connection to my router is alright, so I connected a laptop to it and the laptop works absolutely fine; it gets an IP via DHCP and I can browse my network.
To be sure it was not my network, I installed Raspbian and booted up the Pi. Also with Raspbian, no Ethernet
So, I thought the RPi was defective. I sent it back, received a brand new board today and tested it again after freshly installing the image on the SD card.
It still doesn't work!
I SSH'd into the Pi and had a look at /storage/.cache/connman and only the WiFi settings are there.
It must be something related to my network but I have no idea where to look anymore.
My setup is:
- Netgear Nighthawk D7000 modem/router with latest firmware
- Netgear Gigabit 8 port switch
- Rapsberry Pi 3 with Pi-Hole running and acting as DHCP (router DHCP is disabled)
- All CAT6 cabling with solid connectors
Weird thing is, when I connect a USB to Ethernet adapter, it works...
Do you guys have any suggestions/idea's where to troubleshoot this? Any thoughts on this are greatly appreciated
