looked like missing firmware...so I searched around and obtained

wget https://anduin.linuxfromscratch.org/sources/linux-firmware/iwlwifi-so-a0-gf-a0-68.ucode

sudo cp iwlwifi-so-a0-gf-a0-68.ucode /usr/lib/firmware/

and the pvnm file

wget https://anduin.linuxfromscratch.org/sources/linux-firmware/iwlwifi-so-a0-gf-a0.pnvm

sudo cp iwlwifi-so-a0-gf-a0.pnvm /usr/lib/firmware/

and it works.

So the firmware is still missing in the Debian experimental
