Public bug reported:
Recently (maybe since updating to linux-image-4.4.0-34-generic:amd64
(4.4.0-34.53), i've not used this notebook to much lately), my wifi
connection is unstable, often hangs and therefore spread a lot of bad
karma to all networking applications. My log shows entries of the
following pattern
