Status in linux package in Ubuntu: Incomplete Bug description: This started happening today so probably a new issue caused by a kernel update. Randomly, maybe every 45 minutes wifi disconnects and reconnects. Attached is a log output from dmesg. Looks like issue is in the iwlwifi driver. Disconnect causes TCP connections to drop so it's quite annoying for end user. ThinkPad T460p, up to date kernel on Ubuntu 17.04.
