Unable to contact DHCP server. request has timed out.

    Question

  • Hi All,

    I hope someone can help. This problem has quite frankly kicked my backside and I can only hope someone here can help.

    Last Thursday my PC crashed while I was playing Warcraft and ever since then I have been unable to connect to the internet. The icon shows a exclaimation mark with a yellow triangle showing no network access. My Laptop, iPhone and second PC all connect to the internet fine. Laptop and iPhone are wireless, second PC is wired.

    This affects both my wired connection and my wireless on the troublesome box. Wired shows the above and wireless shows 'no connections are available' even tho I live in a block of flats and my laptop shows 6 different wifi connections. The affected PC is the only one running Win7 (RC1).

    Ok, so backlog finished I have tried the following:

    1) Ran ipconfig /all which gives me an APIPA address as follows:

    C:\Users\All Users.Bedroom>ipconfig /all

    2) I then tried to release/renew to which I got:

    An error occurred while renewing interface Local Area Connection : unable to con
    tact your DHCP server. Request has timed out.

    Fair enough, so i started to look into things that can cause this:

    3) Checked all physical connections to the router, which where fine.
    4) Power-cycled the router
    5) Tried wireless, I got the 'no connections are available' thing.
    6) Replaced the router
    7) Reinstalled the drivers for wired and wireless
    8) Installed different drivers for wired and wireless
    9) Ran the netsh int ip reset and netsh winsock reset catalog commands
    10) Tried winsockfix which I believe is for XP but I figured it couldnt hurt.
    11) Uninstalled all security server.
    12) Turned off router security and set it to broadcast SSID
    13) Installed WinVista in case 7 was the problem, same thing.
    14) Re-installed Windows 7
    15) Pinged 127.0.0.1 to ensure adapter was working, it responds
    16) Checked services to ensure DNS and DHCP was enabled
    18) Updated BIOS
    19) Reloaded optomised defaults
    20) Reset CMOS
    21) Loaded gnoppix to see if it worked. Which it didnt, altho I was not sure what I was doing in linux.
    22) Tried different ethernet cables and ports.

    As I said previously, all other devices work through the same router (even the Xbox) and I find it hard to believe that both the wireless adapter and LAN adapter would fail together. The wireless wasn't even enabled, I rarely use it, mostly its wired on this box.

    I hope someone can help. Please?

    Regards,

    Will

  • Hi There,

    Thanks for your reply. The problem is now fixed. The cause? I have no idea. I got fed up waiting for the internet to work and started to use an old PC. In the meantime the PC was unplugged.

    I plugged it back in to try further to fix it and low and behold it had connected to the network with full internet access. I kinda upset from the perspective that as I never fixed it if it happens again i'll be completely l lost as to what to do. However, in the meantime, at least it's working so I guess i'll thank god for small mercies.

    Regards,

  • Hi Will,

     

    Since the issue occurs even reinstalling Windows 7, I think this issue should be more related to the NIC, please also try the following to have a check:

     

    1.    Upgrade the driver for the NIC.

     

    2.    If you have another external (not onboard) NIC, please try it.

     

    3.    Upgrade the router’s firmware and reconfigure the router.

     

    4.    If possible, please take the computer to another network and see how it works.

     

    Hope this helps. Thanks.

  • I have been grapling with the same issue for the last 3 days. Tried everything mentioned above without any luck.

    Desktop running Win7 Ultimate. Unable to clear IP address like Will01. All the same symtoms but without the miracle that got his machine to work. Help needed.

  • I also am having this exact problem.  I began to lose internet access off and on about a week ago when the computer came back from hibernation, but after I reset the modem it would usually connect.  Starting yesterday, it will no longer reconnect and Dell support indicates it is not a hardware problem but a Windows problem.  I am a novice and would appreciate any suggestions.

  • Im also having the same problem even after doing a clean re-installation of Windows XP- interesting coincidence- I'm also using a NVIDIA nforce 10/100/1000 like Will01... If anyone ever comes across a solution, please let us all know. I will do the same. :)

  • I am having similar issues and cannot seem to get anything to work.  I am running XP and have done the following:

    1) Ran ipconfig which gives me no connection, IP Address, subnet mask or gateway.

    2) Ran ipconfig /all which gives me an APIPA address as follows:

    Windows IP Configuration

       Host Name . . . . . . . . . . . . : Brg 
       Primary Dns Suffix  . . . . . . . :
       Node Type . . . . . . . . . . . . : Unknown
       IP Routing Enabled. . . . . . . . : No
       WINS Proxy Enabled. . . . . . . . : No

    Ethernet adapter Local Area Connection:

       Connection-specific DNS Suffix  . :
       Description . . . . . . . . . . . : Broadcom
       Physical Address. . . . . . . . . : 00
       DHCP Enabled. . . . . . . . . . . : Yes
       Autoconfiguration Enabled . . . . : Yes
       IP Address . . . . . : 0.0.0.0
       Subnet Mask . . . . . . . . . . . : 0.0.0.0
       Default Gateway . . . . . . . . . :
       DHCP Server . . . . . . . . : 255.255.255.255


    2) I then tried to release/renew to which I got:

    Windows IP Configuration

    An error occurred while renewing interface Local Area Connection : unable to con
    tact your DHCP server. Request has timed out.

    Fair enough, so i started to look into things that can cause this:

    3) Checked all physical connections to the switch, which where fine.
    4) Power-cycled
    5) Reinstalled the drivers for wired and wireless
    6) Installed different drivers for wired and wireless
    7) Ran the netsh int ip reset and netsh winsock reset catalog commands
    8) Tried winsock reset catalog, which was not found

    What else can I do?
