I’ve been using DietPi OS on RPi 3B+ for a couple of years now and had no issue. Recently, I switched internet provider and the old one had local IP range 192.168.1.x meanwhile the new one has 192.168.0.x
I have RPi connected over UTP cable, because I use it as DNS resolver with PiHole and find wifi to be unreliable.
I’m not sure what’s the problem, but ever since I connected RPi to a new modem, I don’t see it in modem’s list of connected LAN devices. I’ve tried different cables and tried different LAN ports. Other devices are connecting normally.
dietpi file and these are the settings:
but for some reason, RPi is not appearing on the clients list, hence I have no idea what’s its IP in order to connect or SSH into it.
I could flash a new image on SD card, but I would like to avoid that if possible, since I have everything set up on RPi.
Can someone tell me how to make it appear on the list and get the IP?
Can you connect to a monitor/keyboard? You may need to go into the
dietpi-config settings, and make sure Network Options → Ethernet → Mode is set to DHCP, otherwise it won’t ask the gateway for an IP assignment.
I guess the network settings in dietpi.txt are loaded only on first boot:
##### DietPi-Automation settings, applied on first boot of DietPi only, ONCE! #####
So your SBC is still in the wrong subnet.
You can do what @BluishHumility suggested, or change the subnet in the new router to your old settings, so everything is like before?!
This is correct. AUTO_SETUP parameters are applied on first initial boot only.
Before changing the entire network to a new IP range, it might be easier to change the IP address of the router only.
If this is not possible, connect a screen and keyboard to be able to login locally to change the IP address.
I’ve tried connecting it to a monitor and keyboard yesterday, but it wasn’t showing any picture on the screen, so I assumed something’s faulty and decided to try to change it headlessly, hence why I mentioned dietpi file.
Luckily, I tried again today and it showed the picture as soon as the power adapter was connected, so thank you all for your help!
