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!

      Update /etc/systemd/resolved.conf and add some DNS servers (in this example, 1.1.1.1 is CloudFlare, and 8.8.8.8 and 8.8.4.4 are Google but you can use your preferred DNS servers.)

      [Resolve]
DNS=1.1.1.1 8.8.8.8
FallbackDNS=8.8.4.4

      Restart system resolved:

      service systemd-resolved restart

      Run resolvectl status (or systemd-resolve --status in older versions of systemd) to see if the settings took.

      If they don’t take after a reboot, there’s something else going on.
