    Cannot renew ip or find dhcp server
    Hello,

    I have a connection problem that really has me lost.

    Here's what I CAN do:
    * I can ping a local machine after start up before I release my ip address
    * My Local Area Connection says I am connected and firewalled
    * I can ping 127.0.0.1 after start up before I release my ip address
    * I can ping 192.168.0.1 after start up before I release my ip address

    BUT I cannot access the internet or ping ESPN: The Worldwide Leader In Sports

    I then successfully release my ip address via cmd but cannot renew my ip address and still cannot access the internet. And after I release I can no longer ping any ip address.

    I am trying to fix a friends Sony Viao desktop, model PCV-C11L that is running xp home sp3. I have dsl and I am using a d-link wireless router. My dsl and router work fine as I am running 2 other computers off them successfully (wired and wireless). I am assuming it is not the ISP, modem or router because my friends Viao would not renew at his house or my house. It does not appear to be the NIC card either because I bought him a new NIC, installed it, and had the same problem.

    Any help is greatly appreciated!

    I will paste what cmd is telling me...

    FYI - Have tried all the winsock and netsh fixes on the internet but maybe someone can recommend one to my specific problem/settings.

    Can you ping ESPN directly at 199.181.132.250? If so, one possibility is DNS resolution may not be working. The computer you posted about is using the router for DNS. You'd have to look at the router's config the see what addresses it is using for the ISP's DNS servers. Try to ping them too. If cannot, there could also be a firewall issue at the computer or possibly the router. The other computers may have the ISP's DNS servers configured instead of the router. What is the result of "ipconfig /all" for one of the other machines that is working properly?

    The original IP address configuration should be correct as it is being assigned via DHCP from the router. Releasing it simply breaks everything as a Windows autoconfiguration address gets assigned (169.254.x.x), which definitely won't work.

    try to ping the gateway with a large packet size e.g.

    ping 192.168.0.1 -t -l 8192

    Use ^C to stop. If you get errors you may have a bad port or cable. That -l is a lower case L.

    Well it appears that your wired connection is working correctly as it is picking up a routable 192.168.x.x address, BUT the wireless doesn't have any connection at all, hnece the 169.254.x.x address.

    Focus on why you don't have a wireless connection.

    Try setting a static address in the range 192.168.0.x (x being between 2 and 254)

    Thanks for the response! When I ping ESPN directly with the IP you listed the request timed out. Ping was unsuccessful.

    It looks like my router is using:
    Starting IP Address 192 . 168 . 0 . 100
    Ending IP Address 192 . 168 . 0 . 199
    Is this what you were asking about?

    BTW - you are correct about the initial assignment of the DHCP when I start up windows. Why would I have the proper IP assignments, be able to ping the other local pcs here in my home, but not be able to access the internet or renew my ip? It doesn't seem connected to the outside world. I can't figure out why! Thanks for your help.

    I did as you said and all the ping requests timed out. I plugged the cable into my laptop and it works fine. What port are you referring to that may be bad? The DSL, modem, and router all work fine for my other pcs. I also put a new NIC card in the Viao. That didn't help either. Thanks for your help.

    Sorry but I am confused. The PC with the problem is a 7 year old Sony that does not use a wireless connection. I'm trying to get the wired connection fixed. Guess I was confused by what you posted. Sorry! Let me know what I should try.

    Everything you pinged in your initial post was on the LAN side of the router. I was wondering if you could ping something past the router or if the problem was isolated to name resolution. Seems you can't ping past the router. Do a ping to Amazon.com or some other site on one of the working computers. Note the IP address for the site, and then ping the ip address on the problem computer.

    No, that looks like the DHCP range. When you ping "www.espn.com", the name gets resolved to an ip address. Typically, the ISP's DNS servers do the resolving. Since your ipconfig lists your router as the DNS server, the router is acting as an intermediary. When the computer requests name resolution from the router, the router contacts its configured DNS server (should be the ISP's) and then responds to the computer. The router configuration should have an entry for one or two DNS servers. I usually use those as the next step for a ping test on the WAN side of the router once connectivity to the router has been verified, which you did. Any machine at your ISP is next closest thing to ping and verifies the WAN side of your router connection to the ISP and back. Any trouble past your ISP is the ISPs problem or upstream from them.

    Common possibilties are router or a firewall is blocking the traffic. Do you have MAC address filtering enabled on the router? Does the problem computer have a misconfigured security suite?

    Half the time with Windows XP a renew doesn't work for me either or it takes forever. I have better luck unplugging and replugging the cable. I choose to believe :rolleyes: it's a Microsoft thing, because my Linux stuff never has a problem.

    I cannot ping the DNS from the problem PC. I can from my other laptop. BTW - I can ping my router at 192.168.0.1 but if I open up Firefox or IE and put 192.168.0.1 in the address bar I cannot access the router from this PC. I can access the router just fine from my other pcs at home here.

    There is no ZoneAlarm on this PC. My friend does use SpySweeper as his antivirus. I have also tried installing a new NIC. Do you think reformatting would fix the issue?

    No I do not have any security firewalls but this is my friends PC. How could I double check?

    And what do I do with the manual DNS settings? Sorry, I don't know what to do with those.

    I would suspect that you are either using MAC address filtering or a protocol filter for your ports.

    Write down your current security settings for your wireless and the perform a reset on your router. Power it off and hold down the reset button while powering it back on. Keep the button pressed for about 10 seconds and release it.

    Go back into your router configuration using the default setup IP address and logon (usually no user name and admin for password).

    You will need to renew the IP address from your DHCP server as the DHCP table in your router has also been reset.

    I am not using a MAC address or protocol filter. I have never heard of those either. I can successfully release and renew the DHCP from within my D-Link router WAN page. But ever since then my PC seems even more messed up:
