WRTP54G Network Cable Unplugged Error

I have a WRTP54G (router with 2 Vonage phone ports).  The phone works just fine.  However, every few minutes the PC displays a "network cable is unplugged" error message and I am unable to access the Internet.  After a few seconds, the error goes away, and everything works fine for a few minutes.  I have changed the network cable, used another computer, and I get the same results.  Does anyone have any idea how I can fix this?

I appreciate your response, but how will that help?  I've rebooted all the equipment involved (modem, router, computer) more than once and it hasn't improved things.  The computer continues to cycle between showing the network cable unplugged message and everything working fine.

  • Toshiba laptop (C55-B5302) has "network cable unplugged" error message repeatedly. Why?

    I recent purchased Toshiba Laptop running Windows 8.1 at local Best buy.  The models number is C55-B5302.
    When connected via ethernet cable, I keep seeing an error message in network adapter settings saying "network cable unplugged".
    However, this "unplugged" message switches back and forth repeadedly from "connected" when I am not doing anything to the cable.
    My internet is very sporadic because of this.  I replaced the cable but still same error.
    Any idea on how I can resolve the issue?
    Please help.  Thanks.
    Solved!

    Try downloading and installing the latest LAN driver:
    RealTek LAN Driver File: tc40213700b.exe DOWNLOAD Version: 8.024.1218.2013 Posted Date: 2014-03-13
    If that doesn't fix it, it could be faulty. You might want to exchange it.

    Try the following tips to resolve your problem:
    Disable the Ethernet network adapter if you are not using it. This applies, for example, when running a WiFi home network with computers that have built-in Ethernet adapters. To disable the adapter, double-click the small Network Cable Unplugged error window and choose the Disable option.
    Check both ends of the Ethernet cable connected to the adapter to ensure they are not loose.
    Replace the Ethernet cable with a different one to verify the cable is not damaged.
    Update the network adapter driver software from the manufacturer's Web site.
    Change the Link Speed and Duplex settings (using Device Manager) to use "100 Mbps Full Duplex" or "10 Mbps Full Duplex" instead of Auto Detect.
    Replace the Ethernet network adapter

  • Network cable unplugged problem with WRT54G

    I just got a WRT54G wireless router recently, and experienced some problems with it. There are 5 notebooks in my network using wireless card and 2 PCs connect to the router through cables. The router is with ver 7.00.1 firmware.
    The router is working fine, the problem is sometimes it will show "Network cable unplugged" on my PC, and the whole network will be interruptted, the network will be resumed in few seconds and all machines need to get IP from the DHCP server again. It's quite annoying to be disconnected from middle of the work. I don't know what is the cause, seems like the router is re-reading it's configuration. I have tried to refresh the fireware but with no luck. Someone else got this problem before? anyone has a solution for this? Thanks a lot!

  • Network cable unplugged (BEFW11S4 v3)

    When I plug my cable into the router I keep getting the "Network cable unplugged" error. I reset the router many times, holding down for 30 seconds and still the same error. The wireless still works but can't get any connection with cables. Is there a solution to fix this or is it time for a new router? Thanks for any help.

    On your Desktop computer try to change the Ethernet Adapter card speed and then check.
    To change the Ethernet adapter card speed you can follow the steps on this link.

  • Equium M50 will not recognise the LAN port - error: Network Cable unplugged

    I own a Toshiba Equium M50 and have problems with the Marvell Yukon 88E8036 PCI-E Fast Ethernet Controller.
    I used to connect via an 'ADDON' Modem/ADSL Switch and had no problems. I then replaced the ADDON with a 'NETGEAR' DG834G ADSL Modem/Router to gain the wireless port, and since then my machine will not recognise the LAN port. <error: Network Cable unplugged>.
    I know that the cables are OK as I used them with other laptops and had no trouble. I can also plug in a PCI card to connect without any problems. It looks to me as if the Marvell Yukon 88E8036 PCI-E Fast Ethernet Controller has a problem with the netgear Modem/Router.
    Anyone out there with a similar experience and some advice/suggestions?
    PLEASE

    Hi
    For me it doesnt show like a LAN card problem but your router is a problem.
    Check the device manager if the LAN card was properly recognized. If there are no yellow exclamation marks so everything is ok!
    You can try to delete the LAN card from the device manager and after new reboot install the LAN driver again.
    The issue has stared after installing or connecting the new Netgear modem router.
    Therefore I would recommend to checking firstly the settings or to update the firmware on this router.

  • Connecting Windows XP to Airport Error: "Network Cable Unplugged"

    Situation: Having bought a new computer I gave my old Airport Extreme (a model I bought about 4-5 years ago; one of the white pointy dome ones) to a friend, and attempted to set up their network. My goal was to connect the apple computers (one 2.16GHz iMac and a titanium macbook) to a wireless connection, and then connect their old wireless-less PC with WIndows XP to the airport with an ethernet cable.
    Problem: The wireless network works fine for the Macs, but when I connect the Airport to the PC with the ethernet cable it says "Network Cable Unplugged", and doesn't connect to the internet. I have swapped the cables, so I know that they're fine, and before I attempted all this the computer was corrected straight to the modem through the same port and worked fine, so it's not the port, either.
    Also, I don't think it's the ethernet port on the airport, as I was using it last week with an iMac and it was working fine. But on this I'm not entirely sure. Right now I have the cable from the modem going to the Airport port with the broken-dot circle, and the cable to the pc coming out of the (only other) ethernet port (with the sign <->). If I swap the ports used (with the modem going into the <-> port) the PC works, but the wireless drops out. So that's no good.
    The PC is using Windows XP, which is quite foreign to me, so I don't know the tricks. I haven't found any other threads on here with a similar problem, so if anyone could give me some advice as to how to fix this it would be greatly appreciated!

    By a "128 bit password," I assume that you mean that you have the AirPort Express (AX) set with WEP encryption...correct? ...and that the Mac is connecting to the Internet without any problems...correct?
    If you turn off encryption, can the PC access the Internet thru the AX?

  • Startup gets 'Network cable unplugged' on mini-PCI wireless card

    I recently installed a Netgear DG834GT wireless router and now have an intermittent problem connecting my Tecra 9100 to it. If the 9100 has been shutdown for a while (like overnight), when I restart I always get 'Network cable unplugged' for the wireless connection. Rebooting a number of times (anything from 3 upwards) I eventually get connected to the router and all then works fine for hours. Even a quick restart at this point (i.e. once the wireless card has connected) does not cause a problem but as soon as I leave the machine shutdown for a length of time it fails again at reboot.
    There are no errors in the Event log.
    I am using the built in mini-PCI wireless card and have already upgraded to the latest driver.
    Any ideas gratefully recieved, at the moment each morning is a 20-30 minute frustration of rebooting trying to get my connection working.
    (Running Win2K Professional)

    Checking other boards for help (Netgear etc.) it seems that the 'Network cable unplugged' is a common message when wireless connectivity is failing. However, to prove the point, I have disabled the other LAN card (for which I was also getting 'network cable unplugged' but as expected since it was). I still get the same issue with the wireless card, although now the reboots are slightly more predictable - it normally seems to succeed on the third reboot. I guess disabling the other card has changed the startup timing slightly and in that way made things slightly better.
    Again, any other suggestions gratefully received. As this seems to be a timing issue at startup, I am suspicious that one of the other things that runs at that time is causing the problem.

    More info : I have found that this is time related rather than related to the number of reboots. It always fails on the first reboot after being shut down for a period of time. At this point, however long I wait the connection never comes up. However, if I wait a few minutes and then reboot, the second reboot will always successfully establish the connection.
    On this basis, the problem has become slightly less annoying as I have a workaround - boot once, wait a few minutes and reboot. That being said, any information on how I can isolate this further (e.g. tracing what is running at startup) would be gratefully recieved.

  • Facebook: EA4500 - Network Cable Unplugged

    I have a EA4500 and I'm having a really weird problem. When ever I connect a my router to my PC via Ethernet I get an error of "Network Cable Unplugged". The lights on the back don't even come on but for a slip second when I connect it. But I can also connect my network enabled printer into the same Ethernet ports and it works without a hitch. I have tried switching cables. All I have is Cat6 cables available. But the cable that is connect to my printer its a Cat5e... Is it possible that the router doesn't use Cat6? I mean that would be really odd.. Any help?

    There are just few differences in using Cat5e and Cat6 cable. Both are gigabit cables which you can use for you to have gigabit connection on your network. The EA4500 is a gigabit router so the CAT6 cable should work. The network card of your computer, is it a gigabit card? Have you tried using the CAt5e cable to connect from your computer to the router? How about using the Cat6 cable from your printer to the router?

  • Network Cable Unplugged Status, PC to PLC

    I am working with a PLC connected to the PC via Ethernet.  I would like to receive notification that the cable is unplugged.  Here is the scenario:
    1) Connect to PLC with ConnectToTCPServer (ok).
    2) Send commands via ClientTCPWrite (ok).
    3) Receive status back from PLC. (ok)
    All this works great.
    Now unplug the Ethernet cable.  Go to step 2) and send the command.  CVI sends it and returns a -kTCP_NoError.  The PLC never responds, and the system is frozen.
    Why do I not get an error when using ClientTCPWrite to an open/broken connection?
    Obviously, Windows is aware of the connection, as I instantly get a "Network Cable Unplugged" notice in the taskbar.  Is there an SDK function to do this?
    If you wait long enough, it will trigger the TCP_DISCONNECT in the callback.
    Thanks in advance, David

  • Network Cable unplugged

    I have BT Total Broadband Anywhere Home Hub 2. I have used it successfully on my desktop pc and wirelessly with my laptop. However I went away for 2 months and was unable to use either (everything was switched off whilst away).  On my return the laptop can't connect at all, I just get two grey monitors with a red X and the information 'A Network Cable is unplugged'. I bought  a netbook when away and am having the same problem with that now.
    On the laptop that worked before, on my Network Connections it is showing as follows:
    Local Area Connection 2
    Network cable unplugged
    Broadcom 440 x 10/100 Integrated Controller
    1394 Connection 2
    Connected
    1394 Net Adapter #2
    I have tried connecting to the Hub with an ethernet cable without success and when I run the Hub Manager on the laptop it just says it can't connect with the hub. When I run the Hub Manager on my desktop it says there is no wireless device detected.
    A check on the laptops device manager hardware shows everything as working properly, but when I try the Wireless WLAN configuration utility in Control Panel it tells me there are currently no wireless adapters available and enabled.
    I am getting desperate as I cannot sit at the desktop for any length of time and need the laptop, please can anyone help?

    Hi, the devices you have mentioned are the 'wired' connections.  On most laptops, there are switched you can press to turn on and off wireless, is it posisble this has been done?
    You can check to see if 'wireless network' appears by selecting the Start Button, then click on Control Panel and open, you should see 'Network' (doing this by memory) and open that up, you will see Wired Lan and Wireless Lan.
    If Wireless Lan is disabled, you can right click on wireless lan and enable it, that should work.
