[Anthony Crognale <1354690@xxxxxxxxxxxxxxxxxx>]

Sorry for the delay, I kept forgetting to respond back with school
starting back up.

This seems to be fixed using 3.17.0-031700rc1-generic. I haven't ran
into the issue since installing this kernel.

  I had to reboot before I could submit a report as when the problem occurs, internet connectivity only works for sites without SSL from my observations. Happens about every 3 days of my laptop running at constant use.
