Ethernet doesn't work, can no longer connect at all

Help and Support Help

I’ve been using the same rig for a long while (Rpi 4B installed in an Okto Research dac8 Stereo), but am changing around my network. Since I’ve added an ethernet switch close by I thought I’d connect a network cable to the ethernet port to go wired instead of wifi. I got nothing either in Volumio’s settings or visually on the switch. I turned off wifi in Volumio settings, thinking this would get the wired connection to work. That was very wrong! I can no longer connect by any means. The hotspot isn’t coming up in wifi networks. What are my options here?

Edit: For troubleshooting, I swapped in known working network cables in known working network ports on the switch.
My touch display comes up, but I still haven’t fixed that issue - stuck at the login screen. It does offer another hint that ethernet is not working, though: “WebUI available at ***volumio.local (127.0.0.1)” I can’t change my PC’s address to that IP range to attempt to connect since it’s reserved for loopback.

It sounds like that eth0 connection is broken. Since you already tried to run it on a know working connection and cable and still it doesn’t work.

You can try the following, that will at least bring your WiFi and hotspot back, so you can configure wifi again.

  • Connect a USB keyboard to you rPi4 and we use the touch display as terminal
  • log in with User: volumio and PW: volumio
    • nano /data/configuration/system_controller/network/config.json
  • ctrl+w => and enter in search: wireless_enabled => enter
    • “wireless_enabled”:{“type”:“boolean”,“value”:false} => set "value":true
  • ctrl+w => and enter in search: enable_hotspot => enter
    • "enable_hotspot": {"type": "boolean","value": true} => set "value":true

ctrl+o => enter => ctrl+x
sudo reboot or sudo systemctl restart networking

This should enable the hotspot again.
If that is also failing you need to flash a new SD and start from scratch.

@nerd
Any other advise?

Oh, man! Maybe I’m dumb, but I swear I tried volumio / volumio for user & pwd before and it didn’t work. But it did this time, as did the rest of the steps. It’s all back as it was a few days ago. Thanks so much!
