I have Ubuntu 21.04(Had same on 20.04). And randomly my internet disconnects for 1-5 seconds. When this happends I see this in logs.

14:08:18 whoopsie: [14:08:18] online

I tried reinstalling linux-headers, updating all packages, and ubuntu itself, and upgraded ubuntu from 20.04 to 21.04. Can this also be my network problem and not linux? Because it is in logs and I dont understand whether it network manager problem or my internet problem

sudo lshw -C network results as someone requested:

Whoopsie service does error reporting. Here from logs it looks like it is finding active connection to report error canonical but it is not error or issue.

@KKPatel , but when this happens internet goes off, and what NetworkManager state is now CONNECTED_SITE means?

it is able to connect repoting site. Issue may be at network level. Did you face similar issue on another device in same network ?

I can't actually test on another device, but I will try to do something with my network, changing ethernet cable etc.

Look in your /var/crash directory for .crash files that were created within a minute or two of known internet outages. Those .crash files detail the *actual* problem that you are encountering. They are text files -- open them, look around. The `apport` application creates the .crash files; it is triggered when systemd detects an application crash. `whoopsie` is merely the tiny service that sends the completed .crash file to Canonical's `daisy` server; it is not the *cause* of crashes or network outages.

@user535733 , As I understood if I would have crash file here it is NetworkManager problem?

user535733

12/24/22, 12:37 PM

No. If you would have a crash file there, *the crash file will tell you the problem*.

Edit your question and show me `sudo lshw -C network` and `ls -al /var/crash`. Please describe your network wiring configuration.

12/24/22, 2:24 PM

@heynnema , I edited my question and added what you want

If you are having trouble understanding the .crash file, put the crashfile contents in any pastebin ([here's one](http://paste.ubuntu.com)) and prove the link to that pastebin.

Thanks for the update. However you forgot... Please describe your network wiring configuration. Homemade cables, or purchased?

V.D.

12/24/22, 6:41 PM

@user535733 , I don't see Network Manager crashes at that logs

V.D.

12/24/22, 6:42 PM

@heynnema , I don't quite understand what do you mean by wiring configuration

Describe the ethernet cabling from the port on the rear of the computer, all the way to your router/modem. Include hubs/switches/etc. I'm trying to determine if your problem is there. Are your cables homemade, or purchased new?

V.D.

12/24/22, 7:11 PM

@heynnema , if it is hardware problem I think I should just inspect it by myself, like changing cables etc.

V.D.

12/24/22, 7:13 PM

As far as I know, cables not new. And I think all connected to hub, from where routers go. As far as I remember.

Your answer was incomplete... so I can only guess... connect a new, pre-made, ethernet cable directly from the computer to your router/modem, and see if the problem is gone.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
