• NetworkManager ip-config-unavailable


    Hi guys,

    I have problems connecting to the local wifi (dormitory, I have no access to the router, also every other network worked just fine before). Sometimes it does connect for some reason (with default settings), but when its not:

    Based on journalctl the reason is ip-config-unavailable. I’ve been searching for solutions for a while, what I tried:

    • ipv6 disabled, ipv6 link-local (this way, it connects, but I don’t receive an ipv4)
    • use live iso, to test whether it is a problem with my installation, but it did not help.
    • same machine, win 10 works properly (default settings)
    • same machine ubuntu lts works properly (defaults settings)

    journalctl -u NetworkManager.service

    I would be grateful for any kind of help, ty!

    can you try to stop dhcpcd service?
    sudo systemctl stop dhcpcd

    can you give the exact of what device your wlan is?

    lspci | grep -i wireless
    

    and copy the device number in front of you woreless device output and do this:

    lspci -vv -s 0c:00.0
    

    0c:00.0 should be replaced with what the first command show for the number on your device…

  • lspci | grep -i wireless did not list anything, i believe what you suggest is this:

    02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
    

    output of lspci -vv -s 02:00.0 is:

    (these are while connected to a different wifi, it does not influence the outputs i believe)

  • Yes, mostly wireless works for the command…
