First time in the last 7 years I buy more-or-less a modern notebook. The plan: 1. Install the Debian as a host system and the GuixSD in a virtual machine as a main system 2. Wait until new wi-fi card that works with de-blobbed linux will arrive. 3. Switch to the GuixSD as a host system.
Ok, finally I got an Atheros AR9485 QCNFA125 M.2 NGFF WIFI card for my Lenovo IdeaPad 330-15IKBR notebook. Now network on my notebook works with a Libre Linux kernel and I can switch to a GuixSD as the main host system. Yay!
