Hi there! I returned home and did the following: 1. Removed dkms driver sudo apt purge backport-iwlwifi-dkms
2. Installed the latest RC mainline kernel ls -al total 70352 drwxr-xr-x 2 florin florin 4096 nov 4 23:37 . drwxr-xr-x 5 florin florin 4096 nov 4 23:48 .. -rw-r--r-- 1 florin florin 10897624 nov 4 23:36 linux-headers-5.4.0-050400rc6_5.4.0-050400rc6.201911031940_all.deb -rw-r--r-- 1 florin florin 1179332 nov 4 23:37 linux-headers-5.4.0-050400rc6-generic_5.4.0-050400rc6.201911031940_amd64.deb -rw-r--r-- 1 florin florin 8766748 nov 4 23:37 linux-image-unsigned-5.4.0-050400rc6-generic_5.4.0-050400rc6.201911031940_amd64.deb -rw-r--r-- 1 florin florin 51181032 nov 4 23:37 linux-modules-5.4.0-050400rc6-generic_5.4.0-050400rc6.201911031940_amd64.deb sudo dpkg -i *.deb 3. Restarted 4. Tested the kernel and tried to connect the 2.4 GHz network. uname -a Linux florin-SATELLITE-P50-C 5.4.0-050400rc6-generic #201911031940 SMP Mon Nov 4 00:43:05 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux 5. Cannot connect 2.4, then it connects automatically to the 5 GHz. Cheked, in the additional drivers list it looks like a not functional wifi card, just like before. In Ubuntu 19.04 it worked, BTW, something changed meanwhile. 6. /var/log/dmesg is attached. ** Attachment added: "dmesg log for 2.4 ghz wifi not working on intel wifi card" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848953/+attachment/5302835/+files/dmesg -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1848953 Title: Intel wifi 3165 [8086:3165] subsystem id [8086:4010] not working properly in Ubuntu 19.10 Status in linux package in Ubuntu: Confirmed Bug description: I have a clean install of the latest Ubuntu, 19.10, but since the live usb, a bug appeared.
