An update for Ubuntu was available today and it installed the generic kernel 184.108.40.206.26.
After doing so networking is no longer functioning correctly. My Acer Aspire 4520 has an Nvidia Network card and an Atheros wireless chipset which was functioning properly before the update.
Now when I boot neither are functioning properly. Wireless Networking is still a selectable option but even when enabled the options for selecting a network is grayed out. The Ethernet connection will activate but only after about 3-5 minutes after booting to the desktop.
How can I fix this or roll back to the previous kernel? This is a serious bug and I'm fairly certain I'm not the only one with this issue.
