    No network/wifi for new lubuntu install

    Installed lubuntu 20.04 on new asus l210. Installer announced no networking available so installed just from the usb.

    Installed cleanly, but no internet. Icon in systray identifies as nm-tray, clicking it, left or right gets 3 item menu: Active Connections, Wifi Networks, Known Connections, all of which are dead

    Network directory on Desktop shows an icon called Windows Network, clicking it gives error message, "Failed to retrieve share list from server: No such file or dirctory', followed by second error message 'The specified location is not mounted'

    sudo ip a gives
    Code:
    [sudo] password for q: 
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
        inet 127.0.0.1/8 scope host lo
           valid_lft forever preferred_lft forever
        inet6 ::1/128 scope host 
           valid_lft forever preferred_lft forever

    As wlan0 does not show does this mean lubuntu does not recognize the l210 network card?

    sudo lshw -C network gives

    I'd ask if you've verified that the BIOS didn't disable the NIC first. Go into the bios and check that. In fact, with Asus, you should be able to perform a BIOS upgrade over the internet from inside the BIOS, so I'd suggest trying that. If it doesn't work then you know that the motherboard may have a bad NIC and you should get it replaced ASAP.

    l210? Are you sure it isn't an i210 or i211 both from Intel?
    I know the I211 Gigabit Network is well supported and fast. I have one. It uses the igb driver.
    I know the I210 is supported and fast. I have 4. Neither of those NICs require any special effort to work. The i210 is currently used on my router and not running Linux so I cannot tell you the driver it uses. Sorry.

    I avoid wifi and realtek, so cannot help with that. Sorry.

    Install the driver by double-clicking

    Thanks for your help, I have the download and will transfer it to the asus l210.

    Oh boy, I think this will be a lengthy process, the download was missing one dependency, but that one was missing 3 more, and 2 of those missing 3 more. Someday I am sure I'll reach the end of those dependencies, but right now I'm saying to myself, "who really needs the internet anyway?"

    What about adding the installation medium to the sources?! dkms and build-essential should be there

    Does the system have wired ethernet at all?

    Doesn't seem to be.
    Code:
    /media/q/Lubuntu 20.04.2 LTS amd64 $ sudo find . -maxdepth 10 -iname '*dkms*'                                                                 
    /media/q/Lubuntu 20.04.2 LTS amd64 $ sudo find . -maxdepth 20 -iname '*dkms*'                                                                 
    /media/q/Lubuntu 20.04.2 LTS amd64 $
    Nothing for gcc either.

    I'm mystified. My machine reports:
    Code:
    chili@T440p:/media/chili/Ubuntu 20.04.2.0 LTS amd64$ sudo find . -maxdepth 10 -iname '*dkms*'   
    [sudo] password for chili: 
    ./pool/main/d/dkms
    ./pool/main/d/dkms/dkms_2.8.1-5ubuntu1_all.deb
    The deb file should be installable.

    I notice your file is located in main/d/ on Ubuntu. Lubuntu doesn't have that directory. But thank you very much, now I know where to get it

    Yeah sorry @porphyry52 I just mounted my latest focal media and it's not there.

    We (Lubuntu) don't include all nvidia & like closed-source drivers found on Ubuntu and many other flavors, which is why our ISO still fits on a 2GB thumb-drive.
