  1. "Network Cable Unplugged" on Ethernet Connection


    Let's start at the beginning...
    In early November I broke my collarbone which resulted in my being out of work since. Being unable to really sit in my office at my desk (plugged directly into the modem as I typically am via ethernet), I moved my laptop downtairs and began using the built-in WiFi. For little things like checking e-mail, that was just fine, however, because the only good place to sit in my house had a crap signal, the connection would drop constantly and, being the built-in was only 3G, it was slow as dirt compared to what I was used to. After a couple weeks, I simply couldn't take it anymore and went to Amazon to pick up something that could handle 5G. I settled on an "LTERIVER" 1200Mpbs Dual Band Wi-Fi Adapter. The day it arrived was simultaneously fantastic and the bane of my existence since.

    I plugged the little adapter into a USB 3.0 port and instantly Windows took care of the rest. STUPIDLY, however, I thought to myself "I wonder if it'd run even better if I installed the driver package that came with it." That was over a month ago and I've been quite literally troubleshooting since.

    In short, the driver package (which it turns out is Realtek, just like the built-in Ethernet), included a Wi-Fi management utility. You know, the sort of software that attempts to take over for Windows in managing your connection. Thing is, it didn't work. When it'd launch, it would just blink over and over at me as if it was trying to refresh something but never could. "Ok," I thought. "I'll just kill it. The new adapter was working fine anyway." And thus, I removed it and all was right with the world... until the next day when I needed to plug into my modem via ethernet to do something and, despite my best efforts, the connection continued to say the cable was unplugged. No lights on either side lighting up, I immediately knew something had gotten mucked up in installing the software for the new adapter a couple days earlier. And thus began my personal hell...

    The sheer list of things I've tried to resolve this could make the thread scroll for days so I'll summarize the first week of troubleshooting by saying that after everything that failed... I did a complete clean reinstall of Windows 10 (as in... killed the active partition completely so it'd start over fresh) with no change.

    Here's what I've tried since (and don't be surprised if you suggest something and I reply that I have done that as well - I've honestly lost track of everything I've tried at this point):

    1) Swapped cables (I've tried 4)
    2) Plugged another laptop into the modem using the same cable now plugged into mine (with success)
    3) Updated/Rolled Back the drivers (Realtek PCIe GBE Family Controller btw) - I've tried 3 driver versions now
    4) Went to Half Duplex
    5) Enabled/Disabled the Adapter
    6) Complete removed and reinstalled the adapter
    7) Removed the back from my laptop and ensured there were no loose anythings, and blew things out while I was there
    8) Downloaded the Realtek NIC Diagnostic Utility (which locks up or reboots my computer when I click on the "Diagnostics" option in the menu it provides)
    9) Disabled all other Network Adapters, including the Microsoft ones (Wi-Fi Direct Virtual and Kernel Debug)
    10) Booted into Safe Mode with Networking
    11) Disabled the Energy Saving features of the adapter

    As I said I'm sure there are other things I've tried but at this point have forgotten. I'd absolutely love it if anyone has some unique ideas. As a reminder, I am working with an absolutely clean install of Win 10 here so it's no longer related to installing the new WiFi adapter or the software associated. At this point I want to be convinced it's a hardware issue but, given I've been running on ethernet for 2+ years without any issues until this new adapter came along... that's a hard pill to swallow.

    Help?

    :)

    Ethernet connection issues on Windows 10 PC

    I replaced the connector on my ethernet cabe after the tab broke off. To test it I plugged it into a PS4 and after connecting successfully to the Internet I plugged it back into my PC. Now it won't connect. In Network Connections under what would be my
    network it says "Network cable unplugged". I've tried a different cable and it connected to the Internet without any problems. I've updated the LAN adapter drivers, changed the speed and duplex values and tried a system restore. I'd appreciate any advice on
    what to do next.

    Ouch !!

    Are there any unidentified devices in your device manager listing?

    The lan adapter in the device manager, it says working properly. (Just asking)

    With your new USB wireless adapter out of laptop, please shut off your built in wireless adapter. Likely one of the F keys, older laptops have physical switch front or side. Reboot with cable in.

    Still no luck, look inside port, on laptop, with a small light. There should be eight pins. One might be stuck up or out of place.

  5. Thanks for the response! Alas, yes, according to Windows the adapter is working properly and the only problem is the lack of cable plugged in (again, definitely not the problem).

    I tried each of your suggestions and unfortunately no luck! The pins are pristine and disabling everything but Ethernet and rebooting netted no change.

  6. Okay.

    Can you unplug laptop and remove battery. Then press and hold the power button for 30 seconds. Then leave your device unplugged, no battery and have a coffee or ...... Some devices don't reset properly so I'm, hoping a total lost of power causes a reset.

    While this doesn't make sense could you enter your Bios and see if there is a setting for the Onboard Lan. Disable it and save. Reboot. Then enter BIOS again and enable. (Wants to ensure there isn't something in BIOS preventing operation.)

    You said you tested cable with other device. I think you mention you saw the green and yellow lights when connected to this other laptop. Do you see any lights when you connect to troubled device? For sure the cable is fully seated in troubled laptop. (Okay shoot me for asking)

    I know you said you did clean install. Did you check TCP/IP settings to ensure that when cable is connected it is not in Static IP mode?
    Type ipconfig /all and look under ethernet section. It should list dhcp mode.

    While likely not a router have you powered down your router for a minute and then restarted. Like I said, not likely, but something simple to add to your growing list of things you've done.

    I saw one solution was to head to your adapters properties through Network and Sharing and on "Sharing" tab enable sharing.

    Good luck.

  7. Tried and failed. *Sad
    This was one of the first things I thought of as well and unfortunately, outside of "wake on LAN" settings, there aren't any to enable or disable the adapter itself. That said, I did try to enable and disable those settings without any luck.
    Yep sure did! Instantly as soon as the cable was plugged into the other laptop(s) (yep I tried 3 in fact) the lights on both ends came on. I've tried a few cables now without any change as well.
    Yep sure did! In fact I even tried forcing it into Static to see if that'd change anything. Nope!
    I suppose that's maybe one last thing I could try but, given every other machine plugged into it using the same cable, on the same port (oh I've tried each of those as well), works flawlessly, I don't see what it could be on the router side.
    Ah yes I've even tried that. Starting to think somehow the port has given up on me but it just makes no sense. Windows sees it as existing and working just fine outside of a "missing cable" which I've been lead to believe is typically a driver problem. ....... Which just now got me wondering... I wonder if I partitioned this drive and put another OS on it what results I would have. That's a huge pain in the butt obviously but jesus it would at least tell me if it's hardware or software right?

    One thing you might try, enter BIOS and load and save defaults. I was really counting on power fix. Maybe even try again and leave overnight. (Yes, long shot)

    So you seem to be well versed in the ways of the PC. I would suggest that you download a copy of Ubuntu and burn it to a disk. Then boot from disk. Do not install it on PC, just say I want to try. With network cable plugged in, see if Ubuntu sees network cable. Firefox is part of the standard package, you can even try that. You should see the icons across the top, right hand side. Please keep wireless disable.

    If Ubuntu does not see cable, then you the next step might be disassembling laptop and see if some is amiss. Not much you can fix as it is, in all likelihood solder to board. I see this error with this RealTek device up and down the internet.

    You can by an Ethernet to USB device if we get that far.

    Ubuntu at

    Download Ubuntu Desktop | Download | Ubuntu

    They ask for donation, click not now. This will get you an iso. Use your normal process to mount and burn to disk.

    If there is no try option the you can abandon.

  9. Thanks once again for the reply! I didn't even think about giving Ubuntu a try... I'll do that today I think. Ultimately I just need to know for my own sanity if it's a hardware issue or Windows being a doofus. I already started looking up USB dongles as a final option but I want to be sure it's what I need before I go there y'know? Thanks again!

  10. Great. I was doing more reading about settings but came to the conclusion, we need to know hardware or software. Good luck.

  11. I was SO hoping for a miraculous result with Ubuntu but... and I swear my heart broke a bit when I saw it... Ubuntu says the cable is unplugged when I check the Ethernet connection. *cry

  12. Ouch. At least you now spend your time looking for a new MB or new dongle instead of chasing Window ghosts. There must be something about the design of the NIC. Web is full of this error. Wonder if it is easily shorted? Good luck.

    Shorted or maybe the soldering on one or more pins has failed which can unfortunately happen if you are frequently plugging and unplugging it.

  14. Have you uninstalled the Realtek software that you installed from the Programs and Features list, reboot, go to PC's manufacturers site and install the latest NIC drivers, reboot. You might get lucky and have everything spring to life.

  15. Yep sure did. In fact, I went as far as the delete the OS partition and completely reinstall a complete clean copy of Win10. After even that didn't work, I tried one last time using the driver version from HP to no avail.
