From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[SOLVED] Internet strangely stops working after one day of installation. (lemmy.ml)

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:

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
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
