IP Problems

  1. I got this computer from a friend, fixed it up got it running, but can not release the old IP. I use Comcast(cable) have tried both wired and wireless. I bought a ethernet card, not entirelt sure that one on motherboard was functioning correctly, neither will allow me to release IP and aquire correct one. Comcast uses a dynamic IP, I have two other computers right next to this one both online,(so not the router). DHCP is enabled, release/renew do not work. I have turned off firewall. What is this Winsoc? Help

    disconnect from the internet (or your router).
    get a command prompt (run->cmd) and enter these commands exactly including the Quotes:
    ipconfig /flushdns
    net stop "DNS Client"
    net start "DNS Client"​

    now you can reconnect the cable. Wait 30 seconds and then see what assignment
    has been made
    ipconfig /all​

    Winsock is a special Windows implementation to insert programs into the TCP Protocol stack. You can validate / correct these changes using

    what in gods name does that even means...?

    Ok ...dude i can help you but....... you need to be a little bit more specific and coherent
    on your posting.....

    log on to the C-prompt , click on start , go to run and type CMD.. if you got XP.

    *type : ipconfig /renew or try : ipconfig /release.

    *If this doesnt work , then asign a static ip to your machine , use your
    routers ip adress as your default gateway and use this static DNS : (primary)
    then (secondary) (optional)

    *after your done entering the addresses click ok and then close.

    * go back to control panel , and click on network connections , right click on the connection icon and select disable ....(wait for it until its fully disabled) then right click again and select enable.


    If you have a Cable modem and you have a router in the middle of the equation remember to clone the MAC address of your NIC card directly into your router.

    i hope this helps , if not let me know....
