    No more connection (at all) and no more System Settings

    Hi all


    Runing the command "sudo lshw -C network" results in DISABLED for Ethernet and Wireless.

    More worrisome : no more way to open System Settings or the interface to choose a connection.

    Here is the output of sudo lshw -C connect (I guess it's the relevant output) :

    "Disabled" instead of "Unclaimed" means it's probably disabled in BIOS/UEFI. "Unclaimed" would mean "without drivers" but both are natively supported so it's definitely not that.

    More worrisome : no more way to open System Settings or the interface to choose a connection.
    Please describe what have you been up to just before the catastrophic events.

    Both have drivers according to that output. That's good.

    I'd plug in the ethernet and see if that worked. Then I'd check the BIOS as CW says. Some laptops have physical switches that need to be slide. I have a Dell like that. If I see red under the switch location, wifi is physically disconnected.

    For other laptops, there is a Fn+<some key> to toggle networking/wifi. IDK if this is a BIOS toggle or an OS toggle. For the wifi, in the OS there's a tool called rfkill. This can be used to disable or lock bluetooth and wifi hardware instead of the BIOS. This can be much more convenient. rfkill is only for wireless, not for the ethernet.
