  1. After my pc was infected by a malicious exe it didn't want to boot anymore.
    I then used my windows backup disc repair windows just as described in your thread http://www.techspot.com/vb/topic8356.html. My sytem is back up
    now, but my i-connection is gone and I dunno how to get it to work again. I've got a wireless router which I am connected to by LAN cable...and there is another pc (laptop) connected by WLAN. If I look up run- cmd-ipconfig/all, my ip seems to have changed at the end.The laptop-router connection still works perfectly but not the usual pc-router (lan) What can I do? If you need any details just ask pls

    if I read you correctly, the wireless is running but the cabled system is not.

    use View Network Connections->right click on the LAN to get to properties
    pull down to TCP/IP -> properties
    set DHCP for both IP and DNS
    click ok

    wait 30 sec and the run->cmd /k nslookup www.google.com

    if you get anything other than timeout, you're good to go.

    what do you mean exactly by "set DHCP for both IP and DNS" if I look at the properties ip- and DNS server address are set to automatic. If I also look at the direct LAN connection it says next to "address type, DHCP". I tried the
    "wait 30 sec and the run->cmd /k nslookup www.google.com" you told me and I get the following
    "The server name for the address 149.114.0.5 could not be found
    No response from server
    Server: UnKnown
    www.google.com was not found by UnKnown:No response from server"
    And you read me correctly about the problem.

    192.168.0.1 is your router's address! :eek:

    power off the modem and the router; disconnect your system from the router.

    wait 30 sec

    power-up the modem; wait 30 sec

    power-up the router; wait another 30 sec;

    now reconnect your system to the router; wait 30 sec

    rerun cmd /k nslookup www.google.com

    you *must* be able to get something like:

    Non-authoritative answer:
    Name: www.l.google.com
    Addresses: 74.125.19.99, 74.125.19.103, 74.125.19.104, 74.125.19.147
    Aliases: www.google.com

    Nope, I did exactly that again and just get the same junk, although I must say that I had to translate some of the message because my os isn't english. I hav rebooted as well with no result.

    your system can not SEE your router -- bad news!

    try bypassing the router and cable directly to the modem

    how do you mean "by pass the router" there are no slots left in my modem and like that only one pc would have an i-connection, sry but im a bit confused.

    that is right -- we're trying to determine if your router is the cause of the problem.
    connecting directly to the modem will show
    a) the router is bad
    or b) the problem is in the modem or the pc

    I get "restricted connectivity or no connection" if I connect without router and directly into modem

    call your ISP; the problem is between their system and your modem
