Title:
Frequent disconnects with Intel 8260 wireless NIC
Status in linux package in Ubuntu:
Confirmed
Bug description:
This issue has been resolved upstream and is described in
https://bugzilla.kernel.org/show_bug.cgi?id=117391
The current Ubuntu Xenial Xerus kernel (4.4.0-21.37) is built with a
version of the iwlwifi driver which supports firmware version up to
iwlwifi-8000C-19.ucode. However, the matching linux-firmware package
ships with the -16.ucode version of the firmware, which contains this
bug.
The next stable version of the firmware after -16.ucode is -21.ucode,
but is not supported by the version of the iwlwifi driver in the 4.4.0
kernel. In order to fix this issue, either the minor version of the
firmware (-19.ucode) needs to be included in the linux-firmware
package or the iwlwifi driver in the kernel package needs to be
upgraded with a backport of the iwlwifi driver new enough to support
the -21.ucode firmware.
