Is this a dual-boot with Windows? https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled

@chili555 No, It is single boot.

If you boot into an earlier kernel at the GRUB menu, does it work? What does this tell us: `sudo dpkg -s backport-iwlwifi-dkms | grep Status` Did the wireless work previously? Is this a fresh install?

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.
