Hi, @wjbarid,

In order to determine the right hardware spec on your device, please attach `sudo lspci -vvnnk` output. It will contains subsystem ID that can be used to find the right iwlwifi model.

For bluetooth firmware blob name, you should try:

1. clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git and replace the intel/ subdirectory. Something like:

  $ sudo mv /lib/firmware/intel /lib/firmware/intel.orig
  $ sudo cp -a _git_cloned_firmwares_/intel /lib/firmware

2. power off your machine completely and turn it on again *after* 30 seconds or so.

3. capture the dmesg output for Bluetooth|hci:

  $ dmesg | egrep -i 'blue|hci'

You should find something like:

  Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi
