I ran into the same problem with exactly the same laptop model and network card. It seems that our dual network-bt card is not able to avoid the interference with both interfaces, something that new cards can do by themselves (see this guide in the Debian wiki for iwlwifi).

I found a solution in a bug report (see here), which also involved to create the file /etc/modprobe.d/iwlwifi.conf and setting its content as: options iwlwifi 11n_disable=1 bt_coex_active=0 auto_agg=0 swcrypto=1.

If you already have some content in that file, you can overwrite it using: sudo echo "options iwlwifi 11n_disable=1 bt_coex_active=0 auto_agg=0 swcrypto=1" > /etc/modprobe.d/iwlwifi.conf

Don't forget to reboot your laptop for changes to take effect.

I am using my laptop right know to write this while listening YT with my Bluetooth headphones, no issues so far. As a note, this issue happened to me both in Ubuntu and Fedora.

  • Hi, my bad, I edited my answer to clarify that the file only has that line and that I got no issues after editing it.
