Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I know other people had this problem but I could not find a valid solution which fixes my problem. I have no done a fresh install or anything. Suddenly all my network devices disapeared and when I run lshw -C network I can see my wireless and Ethernet adapter are unclaimed. I ahve no idea how this happened but here are the some more results around this. I am unable to transfer results from my laptop or connect it to internet so OI can only post product details for now:

RTL8111/8168/8411 PCI Express Gigabyte Ethernet Controller

and ifconfig -a only displays lo which is my loopback controller.
