My connection to Wi-Fi is very unstable, it keeps dropping every 5 minutes or so. I have a freshly installed Ubuntu 22.10, I have no idea why it does not work out of the box.

lspci/dmesg output seems fine:

Do you have an idea when can it be?

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.
