My machine: Lenovo T15 Gen2 CPU: 11th Gen Intel(R) Core(TM) i7-1165G7 I tried force installing previous version 1.187.15, but that version isn't available! So, in the end, I rebooted into a live CD and re-installed the OS! In the newly installed OS, I just made sure to NOT select linux- firmware package in the list of available upgrades, and I will stick with version 1.187.15 till I have confidence there is better and working version. NOTE: On an older machine, with an older chipset, I did NOT experience this issue. Older machine: Lenovo x230 CPU: Intel(R) Core(TM) i5-3210M CPU Wifi: Centrino Advanced-N 6205 System ====== I'm running Linux Mint Edge, based on Ubuntu 20.04, but with upgraded kernel (5.11.0.34): lsb_release -rd Description: Linux Mint 20.2 Release: 20.2 Package ======= apt-cache policy linux-firmware linux-firmware: Installed: 1.187.16 Candidate: 1.187.16 Version table: *** 1.187.16 500 500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://archive.ubuntu.com/ubuntu focal-updates/main i386 Packages 100 /var/lib/dpkg/status 1.187 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://archive.ubuntu.com/ubuntu focal/main i386 Packages Expected ======== Upgrade to linux-firmware=1.187.16 Reboot.
