I have a brand new asus laptop with intel AX200 series wifi, and AMD renoir (4000 series) APU. Upon trying to install Ubuntu 20.04 from a live usb stick, I faced a few problems:
I'm stuck on a very low resolution: should be fixed with an amd driver install, so no big deal.
Sadly, I don't have any wifi adapter either, meaning I can't update my graphics drivers or download the updates during the install.
I found a few users reporting the same problems, and claiming it was included by Intel on the Linux kernels 5.1 and higher (see here on intel.com, link found from Intel wifi Support for AX200 (Cyclone Peak))... It should be working in that case, since
uname -r returns
126.96.36.199, but I don't have any form of network connectivity apart from Bluetooth, so I'm stuck on a non working install stick.
I tried loading the intel ucode file from the first link with no success as it seems to require a reboot which I can't perform on a live stick for obvious reasons.
I found traces of iwlwifi on the filesystem of the stick, under /lib/firmware, so i assume that the iwlwifi package is installed. Question is how I can load it to actually have wifi.
Any idea as to what I can do to get out of this situation? Thanks in advance
