    Cannot acquire network address

    Locked

    by acubedwoods3 ·

    My home is setup with a router connected to DSL. One of my PCs was working great, and then now it cannot acquire a network IP address from the router. I checked every possible setting, and even used my laptop on the same cables and router, and the laptop connects no problem, but my PC shows the IP address of 0.0.0.0 and when I try to repair it, it says Cannot Acquire Network Address. And then it sits there for hours trying to get the address. The NIC is working properly, and I even tried a different NIC and got the same thing, it shows speed of 100Mbps and Status: Acquiring network address. I tried uninstall and reinstall of the NIC………… anybody got anything?

      Well first have you installed the TCP/IP protocol or has it been removed by someone or something?

      You may need to reset to a single IP address rather than allowing it to obtain an automatic address but I think that you’ll find the TCP?IP protocol has somehow been removed or disabled.

      If you where to mention what your setup is and how many computers are involved it would be helpful if you are using Windows through a common gateway it is possible that you have exceeded the number of simultaneous connections possible which is knocking this computer off the network or it could be something much simpler but without firs knowing what you are using it is harder to answer this question.

        Yes TCP/IP is installed, I can see the PC from the Laptop, both computers are running WinXP SP2, and they are the only PCs on a 4-port router using DHCP and NAT. I tried to force an IP address on the PC and it still would not connect to the router.

      Well, if you know the NIC works, the cable is good, then the router is the next connection to check.

      I would disconnect router from modem, and directly connect the internet to the computer.

      If this works, then you know its the router.

      Have you checked router configuration and seen what’s in there?
      Some times my Linksys dies and I have to re-enter the information.

      If the router is deemed not working, you have a couple choices:
      1.Use the reset button on router *in back or front, small, like pin hole size* and dump all config, start from scratch.
      2.Install new firmware into router and try that.
      3.Buy new router.

      Troubleshooting, step by step.

      OK I take it that you have a combined DSL modem router and since you have the LT working properly on both connections it would appear to be confined to that particular computer.

      Now since it was working previously what has been added since to prevent it from working?

      I take it that you have tried running the Network Setup Wizard again which would be the normal thing to try and I’m supposing that it has something to do with the installation of SP2 as this is a fairly common problem. So first turn off the firewall that is built into SP2 and see if you then have a connection it is possible that the firewall is blocking the connection although not likely as you can see it from the LT. But can you see the LT from the non working computer?

      I’ve only seen things like this when SP2 was first installed and it corrupted the NIC drivers which you have already reinstalled and I think you said you have even changed the NIC card so that should rule out a Hardware issue although with some of the older NIC cards they didn’t like to play nice and sometimes that had to be moved to a different PCI socket to work A basic M’Board problem there and something to do with the BIOS settings.

      Now if you can see the LT and actually read a file or folder from this computer the network is working properly and the router is blocking its ability to get an Internet connection.

      You’ll have to reset the Router and possibly even load an update to it just remember to only have one computer connected when you set it up and make the first connection.

      If you can not see the LT or actually read a file or folder with the workstation you are using it is something deeper in that computer.

        I would first turn it off make sure everything is seated correctly in their sockets and then reboot and run the Network Setup Wizard again if you get to the end of this procedure and you are not asked to reboot then it has not run properly. Remember to allow the File & Printer sharing option and run the Wizard again.

        Or if you have added something other than SP2 to the computer you could try removing that to see if it works again a lot of the net-workable games can take control of a LAN and delete other programs ability to gain an Internet connection as they establish their own IP/Subnets etc.

        Lets know if that was of any help.

      A question: If you don’t have an IP address, how are the 2 PCs communicating?

      On PC (laptop) that is connected, try releasing and renewing IP address. From command prompt:

      ipconfig /release

      ipconfig /renew

      If laptop will renew address, DHCP from router is working. If it does not renew, that’s your problem (i.e. router is not providing DHCP service).

      A DHCP lease is normally 24 hours and problems may not be apparent until lease expires, PC is rebooted, or IP address is renewed. So you can have some connected and some not until IP address is renewed.

      Is it a Linksys router?

      I had this problem. How I discovered the fix: went directly into my router through IE 192.168.1.1 default password was “admin” and checked the log for errors. What I found was that many times the ip addresses were getting assigned via DHCP (built in)to PCs and not expired and essentially running me out of ip addresses. By the way i made avail on the basic setup page 150 ip addresses. Ok Ok The Fix: shut down all pcs and hit the reset button on the back of the router and everything went back to default factory settings. You are not done yet you now have to setup the router with the setup disc unless you know how to manually do it. I bridged my DSL modem and set my router for PPPoE with my login and password setup. (Experienced user only stuff) Use your disc from your provider it will be easier! Now turn on each PC and you should be ready to go. Good luck!!

      Well the funny thing is that if it’s W2K/XP and can’t find a DHCP, it will assign itself an 169.xxx.xxx.xxx address after X period of time. The fact that it’s not tends to make me think something isn’t right with TCP/IP.

      I have had some dealings with DSL, and sometimes they are a pain because of the software you have to install in order to “see” the connection. Is your DSL service the kind that you have to log into to make the connection, or is it connected all the time? Also, another thing you may try is to configure you Internet options to automaticallly find the IP address settings. Cabling could also be a part of it. Some try to use the software and connect via USB, where I find it easier (especially on DSL Modems) to put a small router behind the DSL Modem and connect the computers to the router. The service provider might also have to have a differnt default gateway setting you may want to check on. Depending on the brand/function and model of your Modem, your computer may only be acquiring an internal address, and the modem will actually acquire the external IP address. Find out which it is and let us know.

      Check the router to make sure that you don’t have MAC address filtering turned on. Many, if not most, consumer routers have IP and MAC filtering.

      Try unplugging the power source from the router, then unplug the power source from the cable modem at let it sit for a minute. Now plug in the power sources to the router, then the cable modem respectively, and after all the lights come up, see if that works.

      if this is still an issue, download winsockxpfix ( works with all versions of windows) and that should repair your problem

      Previously I worked in a networking equipment distributing company, there is a rumors that routers (including modem/router) will work strangely after time being:
      1, If your laptop can access to the router, there should be a function to let you reboot “soft-reset” your router by keeping all your setting to reboot your router.
      2, Since your have know the router’s IP, try assign an IP manually to your PC if your PC can comm. with your router, that means DHCP service is having problem.
      3. Make sure there is no duplicate DHCP server was initiated.
      4. Check DHCP range, make sure it is sufficient for your number of user and MAC filtering as well as other security.
      5. Check DHCP lease time, if feasible, make it lease forever.
      6. Last resort, “hard-reset” your router to make it set as default factory value.
      Just my 2 cents 🙂

      Just with the description you’ve stated, I believe you IP stack is corrupt- try removing IP and reloading it. If you laptop connects to the router no problem, I don’t think it would be the router. I’ve encountered this many times over the years and have found that installing IP from the install CD is best- your install locally may have become corrupt (if you’ve tried this before!)

      Good Luck!

      The solution of using winsockxpfix.exe worked for me too – I had a similar problem – neither NIC in a PC would acquire an IP address. Re-installed Windows, but even the repair option didn’t fix it. Manually assigning an address allowed me to ping other PCs on the network, but didn’t give any more functionality. Strangely, when the ping command was run, the PC beeped once, and also the host name in the first line of the ping response returned odd characters (pinging ?? with 32 bytes…) instead of the IP address. Running winsockxpfix.exe fixed it completely.

        Similar Problem

        by apsolberg ·

        In reply to Reply To: Cannot acquire network address

        I have a similar problem right now. Unfortunately I can’t acquire an ipaddress through either the wireless or a ethernet cord. I have tried on several networks that have worked fine in the past. I tried running winsockxpfix.exe but that didn’t help. I tried to /release the ip address but I get “IP address for local area connection 2 has already been release….” and /renew and I get “An error occurred while reweing interface local area connection 2 : the RPC server is unavailable…”

        I have updated the BIOS and chipset drivers (suggested by DELL). No luck.

        Any ideas?

      My solution: Dell E6500, XPsp3, Dell 2wireGateway internal att router

      by frank.doyle ·

      In reply to Cannot acquire network address

      Dell e6500, router: SBC(ATT) “2Wire Gateway”, OS WinXP sp3. Dell 1510 Network Adapter

      Contacted ATT/sbc. Gave permission for them to get in my computer.
      Solution involved “Network Key”. Was able to get into net after ATT/sbc dialogue and fixes. Subsequently connection “oscillated” between “Connected” and “Not Connected”. Went to ControlPanel/System/DeviceManager>Network adapters. Uninstalled “Dell Wireless 1510”. Rebooted. “Plug and Play” seemed to work. Was asked for “Network Key”,,,,,,, The Network key is the 10 digit number between [ numbers ] on the name tag sticker on the bottom of the 2WireGateway modem from ATT/sbc. Computer became “Connected”. Seems to be working.

      Hope this helps someone.

      Note the “hardwire” connection from the router did work. The wireless one was the problem.
