Bug Description

Please see the upstream bug:
 https://bugzilla.kernel.org/show_bug.cgi?id=194933

The solution is to update the iwlwifi-7260-17.ucode blob from the iwlwifi-backports:
 https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release

Verified it works for my case, would be nice to have it in Xenial repo.
