Reboot and again show us the result of: dmesg | grep wl Please open a terminal and do: sudo apt purge backport-iwlwifi-dkms Yours is not an Intel wireless device, supported by the driver iwlwifi, it is a Broadcom device supported by wl. var/lib/dkms/backport-iwlwifi/8324/build/net/wireless/core.c:431 Please note that the start of the troubles in your log is: Since this question is closely related to the link, would relocating this question be appropriate?
