Public bug reported:
Hello,
I have a quirk to report:
in Ubuntu LTS 16.04-based Linux, under kernel 4.4.0-96-generic, WiFi
disconnects randomly every 40 / 60 minutes.
Expected: Continuous network connection.
Experienced: Periodic network disconnections, only on this device; the
router works fine with all other connected devices, no connection drops.
Hardware: Lenovo ThinkPad T410s, dual Intel/NVIDIA graphics.
Wireless network is managed by the iwlwifi driver (Intel Corporation Centrino
Advanced-N 6200, rev 35).
I currently use LTS kernel 4.4.0-96 over the HWE 4.10 line, because the
former has a much better performance on mechanical disks than the
latter, which is the bottleneck on this generation of laptops.
