@florin, I personally bought one AC 3165 chip online with the same PCI ID [8086:3165] subsystem id [8086:4010], and it works (for both 2.4G and 5G network) just fine with kernel 5.3.0-18-generic you're using as well as latest 5.3.0-45-generic, linux-firmware 1.183.5. Besides, it looks pretty normal in the Additional Drivers. DKMS driver found (but you don't need it on 5.0+ kernels).
Maybe we need to dump your wpasupplicant and NetworkManager logs? For wpa_supplicant, you can modify /lib/systemd/system/wpa_supplicant.service and add '-d' or '-dd' for debug logs: ExecStart=/sbin/wpa_supplicant -d ... For NetworkManager, you can execute: sudo nmcli general logging level debug domain all ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848953 Title: Intel wifi 3165 [8086:3165] subsystem id [8086:4010] not working properly in Ubuntu 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848953/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
