I had a notification in my system tray last night that their was an update that needed to be performed before shutting down/restarting. I selected Update and shut down. Upon booting this morning I could not connect to the internet, despite having the LAN cable plugged in and all. I ended up having to connect via wireless, which i dislike. I have tried various things and cannot get LAN to show up as an option. I have updated the LAN drivers via this site.
