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 @[email protected] and @[email protected] I finally have internet access on my 12-year old e-waste!

    Well the machine’s time is off by a few hours after I power it off for a night. So the time is incorrect right now. This might explain why it suddenly stops when I wake up and reopen it a day after installation. Should I manually set the correct time to fix it?

      If the time is off by that much after being powered off, this tells me two things:

      1. Your RTC battery is very likely dead. Should be simple to replace, it would be on the motherboard but then again accessing it might be a little tricky on a laptop
      2. NTP is probably not set up, or set up incorrectly. It should automatically sync the time on boot

      An incorrect clock can absolutely cause network issues, so I would bet that’s what is causing you trouble
