  • Wireless Connection working. wired connections not

    major dilema

    my computer and my dads computer won't connect to the internet, both are wired connections. But my wireless laptop is connected. All systems running XP 32bit.

    we have a BT homehub 2.0 there are no wires shared by the two computers


    I haven't changed anything since this morning when all was working fine, my dad was checking his e-mails about an hour ago. Then bam neither of us can connect.

    in the network connections it says that there is limited to no connectivity. However on my Dads PC it says that a network cable is unplugged, despite thorough checking of all cabling.

    so far i've done (roughly in order):

    the repair button, it hangs on renewing your IP address and then fails
    disabling connection, enabling then repairing
    un(re)pluging all connections
    pressing the restart button on the router
    turn off router completely for 5mins, thorough check of wiring
    currently running full anti-nasty PC stuff scans

    Some quick googling hasn't come up with anything of help, i typed ipconfig into the command prompt and got this

    ethernet adapter local area connection:

    connection-specific DNS suffix:
    autoconfiguration IP address: 169.254.222.9
    subnet mask: 255.255.0.0
    default gateway:
    any help in solving this overly appreciated


    UPDATE: Just tried the ethernet cable in my laptop with the wireless disabled and was still able to access the internet normally.

    So the problem lies within the two PCs but i don't know why or how to fix

    Re: Wireless Connection working. wired connections not

    First off, have you tried power cycling your router and your desktops? (Turn them off for 30 seconds, then power up your modem, router, and then PCs.)

    If that does not work then...

    There can be a number of possibilities here, mainly it's either going to be your router's ethernet ports have gone bad, the ethernet cables themselves are at fault, or the NICs inside both desktops are dead/faulty.

    You said that you can connect wired from your laptop. Note the port that your dad's desktop is connected to on your router. Unplug his cable and plug your laptop's ethernet cable into that port. Can you connect to the internet?

    If that's a yes, replace your dad's ethernet cable with a new one and try again. If that still doesn't work, then likely the onboard NIC of your dad's desktop is faulty/dead.

    If that's a no, then likely that particular port on your router is faulty/dead.

      update

      he's managed to get the internet back on his PC. By doing a system restore back to the 7th Dec, and then it all worked fine.

      I've tried one, didn't work

      It's not the ethernet cable, as it work for my laptop, but not my PC. And i've had it in both ethernet ports in the back of my PC. So i'm guessing that leaves the NIC.

      Out of interest what would cause that to just die?


      right, i'm able to connect to the router (i think). I went into the connection properties and rather then having IP and DNS set to auto I manually put in the following
      IP - 192.168.1.70
      subnetmask - 255.255.255.0
      default gateway - 192.168.1.254
      primary DNS server - 192.168.1.254
      got most of the values from the info on my laptop and checked with my dads PC once he got it connected again. i chose 1.70 as that was the last known IP that worked (when i hosted a LAN TS server).

      This makes me think that the NIC is working. I've tried to understand what google has been throwing at me for results, and i'm thinking the problem is related to DCHP. What can i do to test this?

        It doesn't sound like anything's wrong with your router's DHCP. If there was the rest of your networked PCs would have trouble connecting to the internet through your router.

        Depending on your router's DHCP settings, I see two possibilities:

        #1: You have more PCs connected to the router than you have available address for those computers. The solution would be to log into your router's control panel and expand the range of IPs (say from 192.168.1.100 to 192.168.1.200 would give you 200 internal IP addresses).

        #2: Your PC may have been assigned a IP either out of range or expired. We can easily release and renew the IP address.

        Can you log into your router's control panel from a working PC? Check if your desktop is recognized by the router (it should have a IP assigned to it). If it doesn't show a IP for the PC (or doesn't show the PC), we can try releasing and renewing the IP from the desktop.

        At which point you can go back to your desktop, open up a command window (XP: Start > Run / Vista or Win7: Start > Type cmd in the search bar and hit Enter). Type in the following:

        ipconfig /release (hit Enter)

        then...

        ipconfig /renew (hit Enter)

        Now go back to your router's CP and see if it has your desktop listed.

          Re: Wireless Connection working. wired connections not

          Managed to get into the router control panel. Bad news though i don't know the password and the router is in my parents room, who are currently asleep

          from what i can see on it though, my PC is listed under the "currently connected devices" but i cant view any IPs i don't think without getting into the settings part.

          will the release and renew still do anything without knowing the IPs of the connected devices?


          another thing that keeps coming up from my searches is winsock errors, is this a likely cause?

          thanks for the help so far!


          edit: just done ping 192.168.1.254, release and renew

            SOLVED

            Turns out nothing was working, even reinstalled windows xp no no avail

            bought a PCI network card and now running full steam!
