    Default no internet after fresh installation of 13.1

    1. I have installed it on the desktop from image dvd
    2. No wired internet connection.

    below is the output of some relevant commands

    3.

    Code:
    # ifconfig -a
    em1       Link encap:Ethernet  HWaddr F8:B1:56:A7:1A:94  
              inet addr:143.239.109.117  Bcast:143.239.109.255  Mask:255.255.255.0

              RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
    4.

    Code:
    # netstat -rn
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

    I do not quite understand why I see two em1 interfaces and why information about ip s is different from ifconfig

    6. what I tried to do was to switch between ifup and NetworkManager. no result.
    7. reboots after the installation did not help.

    8. I can not ping any ip.
    9. I use gnome and do not see network manager applet, its sign appears shortly after switching from ifup to network manager and then disappears.

    no errors (RX, TX) seems allright. Is143.239.109.254 your router or server you connect to WAN ? I assume you use network manager try to look if dhcp is running if you can for example ping this forum or download
    updates (maybe some DNS issue )

    thank you for reply, though I do not quite get what you suggest. As I said I can not ping any ip. ip you mention should be a server.

    Any other ideas?

    Those are two different *rules*, not two interfaces. The second one tells the
    em1 route to addresses 143.239.109.*. With that rule in hand, you can get to
    143.239.109.254. The first of the rules shows that to get to all other IP
    addresses, one needs to use 143.239.109.254.

    I am a little confused about your IP number. Please tell us more about the
    configuration.

    ok, what information exactly would be useful?

    Why do you have a class C address on your box? Are you connected directly to the
    modem without a home router? Most of us have an access point/router in the
    middle and are given a non-routing 192.168.X.Y address.

    this a campus network, so I am not sure of its configuration, but everything works well for nearby computers. The question is are there any means in linux to diagnose the problem?
    and what these means are? from the information I provided looks like ok, but I am far from being expert.

    maybe you coudl try to reintall networkmanager
    Code:
    zypper -f install networkmanager
    and maybe try to set statci route via yast->network devices-> set some DNS servers here are some [CODEGoogle Public DNS: 8.8.8.8, 8.8.4.4, 2001:4860:4860::8888, 2001:4860:4860::8844 [info]

    DNS Advantage: 156.154.70.1, 156.154.71.1 ][/CODE] try different gateway maybe 109.1, 109.0 or 109.255 and set IP forwarding

    Then you should compare your configuration to those. And probably
    contact the campus IT staff. On some sites, you need some kind of
    authorization procedure.

    Start with pinging yourself (143.239.109.117), and then the gateway
    (143.239.109.254). Then pinging google (by IP, not name).
