XUbuntu 20.04 Network Device disconnecting every few minutes. Kernel Driver e1000e

I am hardwired to a network. My computer is losing internet connection every ~2 minutes for ~2 minutes. My friend's computer hardwired to the same network is not having any outages.

It seems like this may be a known issue: bugzilla.kernel, bugzilla.redhat.

I believe I updated my system a few days ago and the problem started today.

What should I do to stop this problem from continuing?

Attempted solutions and results:

  1. Failed: Change MTU from Automatic to 1492 in network connection settings GUI interface.

  2. Failed: Change link negotiation from "Ignore" to "Manual"

  3. Failed: Change link negotiation from "Ignore" to "Automatic"

  4. Failed: Install the driver here: https://github.com/koljah-de/e1000e-dkms-debian

  5. Failed: Change ethernet cable.

  6. Failed: Update kernel stack to HWE 5.13 Kernel (https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Server). I successfully upgraded the kernel but it did not solve the problem.

You weren't specific as to which kernel stack you're using (*Ubuntu LTS releases have two kernels stack choices + potentially OEM options*), but one of the kernel bug reports only mentions 5.3 & 5.4RC status kernels; so have you tried the much newer HWE stack? (*it contains far newer than is mentioned in that report*)

5.4 is the GA kernel stack; 5.13 is the kernel currently being used if you're using the HWE kernel stack; ie. https://wiki.ubuntu.com/Kernel/LTSEnablementStack

@guiverc: I haven't messed with drivers or the kernel at all. I installed Ubuntu 20.04 back in May of 2020, give or take, and done updates as prompted. My network device worked fine until today. I am happy with staying away from bleeding edge kernels. Is there instead a way to identify which update broke this and revert it?

Ubuntu LTS releases come with two kernel stack choices; for Ubuntu Server the default can be set at install time but if that option is left to default the GA stack is used; with Ubuntu Desktop the HWE is the default; with *flavors* it's GA for 20.04 & 20.04.1 media, and HWE for 20.04.2 & later media... ie. two choices (the link I gave is one option; but I'd follow what @N0rbert provided & have up-voted it..) FYI: To test the other kernel stack; I'd likely use *live* media rather than install; ie. not impact your existing install, but it'll depend somewhat on your media given Server ISOs use GA

I installed N0rbert's link's driver and restarted. Let's see how it goes.

Did not work. I got about 3 minutes of network before it disconnected.

Then try [HWE 5.13 kernel](https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Server). And maybe check Ethernet cable.

Why aren't we talking about just undoing whatever happened ~3 days ago? The system ran fine for nearly two years.

Tried swapping the wire. Strangely things were stable for about 15 minutes, and then it started cycling again.

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.
