Please [edit] your question and add output of `lspci -knn | grep Net -A3` terminal command.

@darth_epoxy thank you for your help. I tried to run this comment (edited in question), but not resolved.

Thanks @Pilot6 yes we should determine the driver. Try this at the command line `lspci -vvnn | grep -A 9 Network` as an alternative and let us know. Also, feel free to safely run the `sudo apt autoremove`

It seems that you may need to upgrade your kernel version.<br/>And so unfortunately there is no simple answer to your question.<br/>Read here [Canonical](https://ubuntu.com/security/notices/USN-5780-1)

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.
