I had the same issue today (May 5th 2022), and the workaround proposed by Giacomo Tazzari worked just fine.
Strangely, the adapter was working just fine after the Ubuntu 22.04 installation (earlier this week). So maybe some recent update caused the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967842 Title: Ubuntu 22.04 Beta: linux-firmware iwlwifi-9260-th-b0-jf-b0-46.ucode - Wireless-AC 9260 not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1967842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
