This is an Acer Aspire one laptop, with a 32 bit CPU and Debian 12.7. Whenever I install Linux on it, the Internet works for about one day. And when I boot it up the next day, it just stops working. This is the case for WiFi, Ethernet and USB tethering via Android.

After running networkctl it gave me this:

I can ping 8.8.8.8 in this state, but not gnu.org. I can’t open websites in Firefox either.

Then I ran “sudo systemctl start systemd-networkd”. The networkctl output changed but everything worked exactly as the above two images. Couldn’t open websites still.

Yesterday everything was working perfectly

Edit: Thanks to @nanook@friendica.eskimo.com and @MyNameIsRichard@lemmy.ml I finally have internet access on my 12-year old e-waste!

    Why are you using networkd instead of networkmanager on a desktop? The two don’t work together.

    Anyway, it looks like a DNS problem. You can manually specify DNS servers (like 8.8.8.8, 8.8.4.4) in whatever network management you’re using.

    Alternatively you can edit /etc/hosts (I meant /etc/resolv.conf obviously) and then make it immutable (chattr +i /etc/hosts) to prevent changes.
