Thread: no connection / DHCP with eth

  1. #1

    Default no connection / DHCP with eth

    I encounter a strange behaviour when installing 15.2.

    network connection to the router fails via eth0 / LAN cable.
    the error message says "IP configuration unavailable".

    strange:
    - the installation itself was done via the LAN cable. the error occured after the first boot.
    - the LAN cable is working fine with another computer
    - WiFi is working

    journactl -f says:

    Hi!

    Are you using NetworkManager or Wicked (see YaST -> "Network Settings")?

    Did you configure the LAN interface, i.e. DHCP ipv4 and/or ipv6, depending on your DHCP server/router settings for your LAN?
    Kind regards

    I'm using NetworkManager, as you can see from journalctl output.

    eth configuration (in plasma/Network/Manager) is identical to that on the computer on which eth is working (with opensuse 15.1). no configuration was modified on the router.
    I didn't change any configuration on the router since it works for other computers for cable as well as for WiFi.
    Is that what you were asking for?

    Do you observe the same problem with wicked or after configuring IP manually?

    seems to work with wicked:

    ip addr with NetworkManager:

    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 54:e1:ad:56:8b:19 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::c8b6:dc43:a5a6:8122/64 scope link noprefixroute
    valid_lft forever preferred_lft forever


    ip addr with wicked:

    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 54:e1:ad:56:8b:19 brd ff:ff:ff:ff:ff:ff
    inet 192.168.178.58/24 brd 192.168.178.255 scope global eth0
    valid_lft forever preferred_lft forever
    inet6 fe80::c8b6:dc43:a5a6:8122/64 scope link noprefixroute
    valid_lft forever preferred_lft forever


    eth works under windows (dual boot)

    after setting the IP address by hand for IPV4, eth connection was stablished

    but how to make it work with DHCP??

    Default Re: no connection / DHCP with eth

    Set in NetworkManager (Taskbar widget) the IPv6 -> Method -> Ignored.

    Try again (press "Connect"/"Vebinden" for "Wired Connection 1"/ "Kabelgebundene Verbindung 1")...
    Kind regards

    Journal?

    Remove the whole interface from NetworkManager and create fresh with IPv6 ignored. Reboot the FrizBox...
    Kind regards
