Thread: internet stopped working all of a sudden

    Default internet stopped working all of a sudden

    Hi guys

    I've had Opensuse 11.1 installed for quite some time now, all has been well, now all of a sudden my internet has stopped working....

    Im using wired adsl2 router/modem via ethernet. I've never had internet stop working on opensuse before... strange....

    but i know its not the hardware... because i reboot into mandriva and internet works straight away, but when i boot into opensuse, Nothing.... not even the ethernet light at the back of the pc turns on.....

    so something is not loading on boot.... im not as familiar with yast as i am with mandriva's control centre, but i went into network settings in yast and made sure eth1 was set, with connect on reboot for my network card and dhcp ticked, but still not working... so im stumped.....

    any help appreciated......
    thanx

    If I were sitting in front of your computer the first thing I would do: become root and then:

    Code:
    ifconfig -a
    and

    Code:
    route -n
    to see what the configuration is.

    no ideas anyone?

    it would be alot easier if Yast had something similar to mandriva's control centre.... which is "creat a new connection' then it allows you to set it all up from scratch.....

    But its a bit weird in yast, theres only DSL settings, which isn't the right tool for the job for me as all those settings are configured by my router/modem....(eg adsl username/password/country settings etc etc)

    and theres only network settings which i've set up correct and my internet is still not working........

    its almost as if the correct driver/kernel module isn't getting loaded on boot even though it looks to me as if I have it set up correct........ arghhhh.

    Modules are loaded, otherwise devices would not appear. As you can see, the eth1 devices gets an IP as well: 192.168.0.2
    I assume the router's inside IP is 192.168.0.1, configure that as a gateway address in Yast - Network Devices - Networksettings/devices.

    The problem might also be in IPv6. It can be enabled/disabled in the same part of Yast. Disable it. It will tell you it needs a reboot to be enabled. Get back with results please.

    Good luck

    arghhh! Lol

    I really don't want to do a reinstall and have to upgrade to kde 4.3.1 from 4.1 and redo all my settings for everything for such minor problem that i can't figure out :'

    looks like its heading that way.... unless i get lazy and install the latest kde maintained live cd

    Like the others mention, it looks like eth1 interface is configured and connected ok. Could this just be a nameserver issue? For example, maybe you can ping your router ok, but just not resolve an address?

    cat /etc/resolv.conf |grep name

    It is interesting that you have 3 ethernet devices present. While I am not sure that anything is amiss here, maybe give us the output of these commands anyway...

    /sbin/lspci -k |grep Net -A 2
    /sbin/lspci -nn |grep Net
