Today I did a regular update for my Ubuntu 14.04 installation on my Dell XPS 13 and the update included a new kernel (I guess it was 3.19.0-65). I noticed that the wireless stopped working after the update and thought that it would be a good idea to switch to an older kernel but it seems that somehow I have messed things up.
The status is: I still have kernels on my machine (3.19.0-65, 3.19.0-64 and 3.19.0-51) and it boots to unity. Screen and touchpad are working, all looks nice, but: It does say that it does not have any network devices at all, so I am totally offline with the laptop.
iwconfig simply gives
lo no wireless extensions
and nothing else. I found the page My wireless/WiFi connection does not work. What information is needed to diagnose the issue? to diagnose, downloaded the script and tried to transfer it to my laptop with a memory sitck. But my laptop will not even find a usb memory stick anymore! With no network and not usb I am kind of stuck here…
So I am looking for:
- How do I get my machine up and running again?
- If the system is broken beyond repair, how could I still get a backup and a reinstall?
