    I didn't go through all of your output to see what you had there.  
    What I caught from you were two things:  

    - You have set a static IP address
    - You need this done in a hurry

    I have 2 Linksys routers that are linked together.  I have found that
    Linksys support is really great (and quick) at getting you up and
    running.  As long as you have access to the routers web admin page,
    they can take you right through that. Call them!

    They have folks that can help with linux, but I would get your card up
    right first.

    Basically, DON'T set up a static IP address (YET!) for your router or
    your eth0 card.  Let the router serve your IP addresses and dns.

    Dump your cards configs, and set up your card from scratch using Yast!  
    I say this only because I have experienced countless hours and days
    of pain trying to tweak something that is really simple.

    If you can figure it out with this, great!  If you need details on it
    let me know.  I have a Linksys RT31P2 (wired with phone ports) and a
    Linksys WRT54G (wireless) that is connected to the wired router.  
    Both are on different networks (15.1, 1.1), and both router are set
    up by default to serve DHCP for the internet and the network.  I also
    have setup in the past both eth and wlan cards on these routers.

    What I'm telling you is the simplest and fastest way to get it done.  
    You can tweak it later if you need to.
