Unplugged network cable

Hi all

I was invited to take a look at an old enough box office running Windows 7 32 bit Ultimate edition. Map of oboard nVidia nForce network constantly reports that a network cable is unplugged - this isn't, of course.

The owner told me that, once the machine has started, it must plug the router until the machine detects the connection. I brought the machine in my network and to see the same kind of symptoms, except that it may, or may not, to detect the connection to chance, no matter if I power cycle the switch from office to which it is connected.

I tried several different cables, ethernet, mine and without changing the owner

I found that the permutation of the speed / duplex settings on the Advanced tab in the properties of the controller to auto to 100 Mb Full Duplex causes the connection be detected until the computer is restarted. At that time, cable disconnected message returns until I exchange the speed / duplex back to auto.

I removed the controller from Device Manager and hosted Windows redetect, uninstalled and reinstalled the driver etc.

I have reset winsock / tcp.

In desperation I even set up a PCI network card (Realtek, I think from memory) and to people with disabilities the controller on board - the PCI network card shows the same problem, but is slightly less willing to connect when the speed / duplex setting is changed.

I'm sick of ideas on this one - any suggestions would be much appreciated!

TIA

Rob.

You may be able to find an Ethernet card that will fit the old man.  Should not be too expensive.

    I found the problem (s), even if I am always left with a few questions.

    During this process, I have disabled the firewall, but that did not help. However, I noticed 'tweaks' accessed via the tab 'Advanced' in 'Microsoft Firewall' which looked like, they must be checked in order to access the internet. I checked these and reintroduced the firewall. After I got things working, I unchecked them and things still worked so I obviously don't understand what these parameters.

    The solution:

    (1) I have to go straight from the modem cable to the computer. I can't have a cable modem, router wireless, computer, even if using hard wire, and even if this same configuration works with another computer. Also, I can't use a cable length to go from modem to the computer. So, it seems to have had a problem of cable length. Power problem? Only connected to this computer devices are the mouse, the keyboard and the Ethernet. Would not this be fixed with an upgrade of the power supply? Or is it due to the quality of the Ethernet hardware on the motherboard? It's a Dell Vostro 200.

    (2) in back and forth between configurations while following the problem, you must think to unplug the modem to reset between each configuration. You may have stumbled upon the solution, otherwise he's not shot. Also, I unplugged the cable from the modem when you reset data cable - do not know if it was necessary. I wanted to limit the degrees of freedom that I had a lot, as it was.

  • LaserJet Pro 400 M425dn: Unplugged network Cable

    I just bought a printer LaserJet Pro 400 M425dn and tried to set up on my university network. I have a static IP address for the printer. However, no matter how to set up the printer, I see only cable disconnected in the status screen of the network on the touch screen. The cable and the wall socket is working, since I can connect to a computer using their network.

    There is no flashing lights, close the network card. Is the printer network card defective?

    The network port is part of the trainer so if defective, you need to replace the formatter.  Having said that I had one who wouldn't not connect to the network.  I don't me remember not if the link lights have been turned on or off, but he finished the port has been wired incorrectly.  The pairs have been overturned as a crossover cable, and we have done the same and connected a laptop to the port and it works.  We discovered that the laptop automatically detected the pair reversed and connected.  Not sure if this is your case, but I propose the printer to another location just to see if I get a clear link to another location.  If no link light, then I'm afraid of the trainer will need replacement.

  • Startup gets "Network cable unplugged" on mini-PCI Wireless card

    I recently installed a Netgear DG834GT wireless router and now have intermittent problems connecting my Tecra 9100. If the 9100 has been off for awhile (like overnight), when I restart I get always "Network cable unplugged" for the wireless connection. Reboot several times (anything from 3 upwards) I finally get connected to the router and everything then works fine for hours. Even a quick restart at this point (that is, once that the wireless adapter is connected) does not cause a problem, but as soon as I leave the stop of the machine during a time he fails again on restart.

    There are no errors in the event log.

    I am using wireless mini-PCI cards and have already updated to the latest version of the driver.

    Any ideas gratefully received, for now every morning is a 20 to 30 minutes of rebooting frustration trying to get my connection work.

    (Running Win2K professional)

    Hello

    As far as I know, the unplugged network cable message just for LAN (Local Area connection-LAN) and not wireless.

    If you want to check this map to disable LAN in Device Manager. After starting the laptop turn on the wireless card, check the status using the FN + F8 key combination. Wi - Fi is activated after a short time, you should be able to use your wireless network.

    You can enable the option Show icon in notification area when connected. You can find it in the properties of wireless under the general tab.

  • Laserjetpro m252dw: printer says network cable unplugged when plugged into a wall outlet

    My printer worked fine and all of a sudden, he is no longer prints and the display shows: "network cable unplugged".

    I turned off the printer, it is plugged. Does the same thing for the modem and the router. The problem is not resolved. Help, please

    Hi @Kajosil,

    Welcome to the Forums of HP Support!

    I understand that you are unable to print because of this "unplugged network cable" error message on your HP LaserJet Pro M252dw Color printer. I will definitely do my best to help you and don't forget to come back to this thread and mark "Accept as Solution", if I have successfully helped solve you the problem. If you want to say 'Thank you' to my effort to help, click on the "thumbs up" to give me a Kudos.

    It seems that the printer does not have enough power to work properly, or there is a problem with the cable/port.

    • Please click here to update the firmware of the printer.

    Make sure that the ethernet cable is connected to the appropriate port on the back of the printer.
    See the section: 'Return product view' in the user manual for more information.

    • Have you tried another port on the router?
    • Have you tried another ethernet cable?
    • Check if the cable is damaged or deformed.

    If the problem persists, I would like to do a hard reset and electric drain to see if this will solve the problem.

    • To eliminate other causes, unplug the USB cable or telephone (fax) for the test so attached.
    1. Let the printer and disconnect the printer cable and the wall socket for 60 seconds.
    2. Press and hold the power button for about 15 seconds to drain any residual electric load and then release the power button.
    3. Reconnect the power cable to the output of the printer and the wall, and not a surge protector. This ensures that the printer is full on and can help this situation.
    4. Make sure that the printer is connected directly to a wall outlet (do not use a bar or a surge protector).
    5. Try another outlet to power/room.
    6. Try a different compatible power cable.

    If the problem persists, I would try resetting the NVRAM. This will outline the printer back to the default settings. The network must be configured again. I can send you this information in a private message. In the forum next to your handle name simply click on the envelope to see.

    I hope this information is useful. Please reply to this message with the results. Good luck!

  • Problems connecting to internet - says network cable disconnected, not sure I have the correct driver installed.

    Had a big storm - got the new modem.  but they said that my drivers where missing or damaged.  Downloaded Marvell Yukon of gateway - to the GT5432 model. Always says cable unplugged network. However, Bishop says peripheral device works correctly. Don't save: no update-unable to connect to the internet.  I uninstalled and reinstalled; rebboted, etc. - still nothing. It has a problem with the PCI connection - no driver, but I don't see anywhere to down load or know what to download. Oh and another adapter on - think 1394 - when I turn that on and off the wonder; It shows the signal for the 1394---400 and does not say his unplugged, but still can not connect to internet.
    The "old" computer to try to find information; noticed that said, unplugged network cable but it allowed me to connect to the internet. When I disabled the 'extra' adapter message there went, speed signal only at 100 than at the 'old' calculation is not any other PCI devices connection listed.

    I'm not sure of what continues.

    The 1st computer was working fine - then picked it up to move it to where it belonged to my office and that's when he went out-made no sense to me!

    Because you seem comfortable opening your computer, have you tried re - a corner of the map (with power off, remove the card and reinsert it into the slot, be sure to exercise static precautions if you are in an environment of low-hu7midity).  If there is an empty slot, you can also move the map Marvell to another location.  See the comments below.

    It's a long shot, because even if you did not provide the complete ipconfig output, the data that you have provided appeared to be normal, but...

    Open network connections (start > run > ncpa.cpl > OK)
    Right-click on the icon for your network adapter, and then select Properties
    You should see a screen like this--> http://screenshots.modemhelp.net/screenshots/Windows_XP/Network_Connections/Local_Area_Connection/Properties/General/Index.shtml
    Issues related to the:
    In the upper area, under 'Connect using' said 'Marvell Yukon 88E8039 PCI-E Fast Ethernet Controller?  If this is not the case, what does say?

    In the second box, what are the items are listed under "this connection uses the following items"?

    The only other thing I can think is that the Marvell Ethernet card was damaged in the same storm that got your original modem/router.

    *******************************************

    According to Gateway, the GT5432 has 4 card slots:
    A PCI Express x 16 (GUI)
    A PCI Express x 1
    Two PCI Conventional

    Your motherboard should look like this:

    Orange, top, connector is the PCI Express x 16.  You probably have a video card in this slot.

    The short white connector is the PCI Express x 1 connector.

    Two more long white connectors are the standard PCI slots.

    If I understand your installation, you should have the Marvell Yukon map into the slots of two down and your Agere modem on the other.  As long as you have the SMC1244TX PCI card, why don't just remove you the Agere modem or the card Marvell and insert the card CMS in one of the two PCI slots?  You are not using the modem and the working hypothesis is that the Marvell card does not work, so there is not much to gain by leaving a card in your computer.

    Download the user guide and drivers for the SMC here--> http://www.smc.com/index.cfm?event=viewProduct&localeCode=EN_TUR&cid=9&scid=51&pid=238 map

    Moreover, assuming that your open slot is the short PCI Express x 1 slot, you can buy another Ethernet card that will work in this niche: see--> http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100010064%20600016290&IsNodeId=1&bop=And&Order=PRICE&PageSize=100

    If I were you, I blow up the cheaper models and get the Intel EXPI9301CT $ 36 10 / 100 / 1000 Mbps PCI Express Desktop Adapter Gigabit CT.  Note that this is the same card with a similar name (with close to 400 customers) which sells for $29,94.  The price difference is because the cheaper "BLK" letters in the description, which means that it is "sold in bulk" and has no drivers, user guide CD or anything else in the box.  There are several negative comments from people who do not understand this difference and then had trouble finding the driver for the card on the Internet.

    Hello

    I have the same problem if I stand for laptop and access point at the same time. If the access point is already in use, the connection is established shortly after. First the access point must establish a connection to the modem. Now the wireless connection is not available.

    I guess after the second reboot, the connection between the AP and the modem is already finished and you can use the network wireless successfully.

    Hello Verashanley

    Since how long did begin?
    You have added a new software or hardware to the system?
    If the issue took place recently then you can try the system restore.
    If you have recently added anything to the system (hardware or software), then remove.
    If the system restore does not then check in Device Manager and verify that the network card is considered and no errors appear.
    To open Device Manager, click Start, and then click Control Panel. Click performance and Maintenanceand then click System. In the hardware tab, click Device Manager.
    Check the type of network card you have and that you try to update the drivers from the hardware manufactures Web site.
    Also, check the connection for the network adapter. Do you see any physical damage. When you plug the NIC saw all the lights on the network card lights up? If not, then you can deal with a hardware problem and need to contact the manufacture of the system and see about obtaining the card replaced.
    Let me know the results. Thank you.
