Network trouble, inet connection when moved

  1. I build systems in my condo.
    I use cox cable with motorola surfboard SB5100 & linksys WRT54G v3 wireless.

    I have one hardwired and one wireless.
    When I build new systems they are hard wired to the router after windows install.
    They obtain everything auto, ip, dns, dhcp etc. and connect to inet with no trouble.

    1 in 6 systems will have a problem connecting to inet directly through modem or router/modem,
    once system is sold and moved to new location. All machines have onboard nic's 10/100 min.

    In order to access files I keep on my main machine, to complete installs,
    I setup a network using the network setup wizard naming the network SOCRATES.
    I also use on all machines:
    run/cmd/net user guest ******, to protect guest account access.

    With the troubled machine, when I run/cmd/ipconfig, everything shows up

    I am un-able to ping anything, regardless of modem or router use.
    Normally I would log onto the router and DHCP release/renew but I'm not able to log on to the router,
    in this case a new D-link wireless 4 port switch.
    2 other machines at this new location are able to us all three combinations; modem direct,
    or modem/router and wirleless to access inet.

    I'm not sure what I'm missing.....any ideas? :confused:
    Thank you!

    Starting from ground up..

    Do you have an ethernet link? (Link light on the router and NIC)
    Do you have proper drivers for the NIC? (Are you sure you don't have some IEEE1394 connection instead of a LAN connection configured?)
    Do you have TCP/IP installed for the NIC and configured to get everything automatically?
    Do you have the DHCP client service running?

    Disable all kinds of firewalls, VPN and packet capture software.

    Set a proper TCP/IP configuration manually.
    Can you ping the router?
    After attempting a ping, can you see the router's MAC address in "arp -a" output?

    Thank you Nodsu

    I should be able to ping the onboard nic but have not attemped yet, though
    is'nt ipconfig a local ping too?
    I'm also tempted to install an intel nic card and shutdown the onboard nic
    just to see if this may be the trouble.
    I believe this machine has via chipset, so maybe the hyperion drivers will clear it up.
    Thank you Nodsu, for helping me get my trouble shooting in order.
    I will see where I get with this and post back what I get.

    first off try crossover with a comp that has the network working already and see if you can 'see' each other and transfer files through that way. that should demonstrate if the ethernet port is working properly
    check for any jumpers that relate to the onboard network from your mobo manual and see if it needs to be set specificaly..
    hope it helps..

    Very good call!
    However when the system(s) are connected to my home network everything is working proper, it's when they leave to new location.

    I have gotten things sorted now.
    It turned out to be, "file and printer sharing" & my established network "SOCRATES".

    When I turned off file & print sharing, deleted any shares showing in explorer view of networks, I was able to reset the machines network to MSHOME.
    Which I guess, released the mac address of the onboard nic?!

    Then, at new location, setup a fresh network allowing it to detect new enviroment. Now I connect them directly to cable modem, then
    let Linksys cd setup the connection to the router.

    Thank you EVEYONE for your help!!! :grinthumb
    This has helped me in my biz a great deal!!!
