Public bug reported: The stock firmware for this device /lib/firmware/iwlwifi-7265D-16.ucode is crashing.
Downloading the latest firmware (/lib/firmware/iwlwifi-7265D-21.ucode) isn't supported by the existing iwlwifi driver, and so the driver likely needs to be upgraded (or downgraded as well (https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/backport- iwlwifi.git/?h=release/LinuxCore18). I can also confirm that wifi *did* work successfully on 15.10 before upgrading to 16.04, although the kernel module required frequent restarts due to this bug: https://bugs.launchpad.net/ubuntu/xenial/+source/linux/+bug/1570595 A detailed message about the firmware crash is located in the attachment from dmesg output. Thanks.
