    Dear Friends;

    In my office, a network cable is being in use for a desktop PC and data sends receives without any problem. I have a Dell Laptop and I connect networking cable at many other places (due to meetings) within our mill and every where I face no any problem but when I connect network cable of my office (which works well with Desktop PC) with Laptop, the message “A network cable is unplugged” appears. I replaced the RJ45 connector and rechecked the pin configuration and found every thing ok but even with new connector, problem remained the same.

    I installed a “D-Link”, connected Desktop cable to D-link and connected a new cable from D-link to Laptop and found that system was sending the data but not receiving.

    Anyone has any idea to resolve this issue?

    Open Device manager then
    the controller under the Network Adapters.
    Double click the controller to open its properties window.
    click on the Advanced tab (This is where you can change the speed and duplex settings).
    Select Speed & Duplex on the left side of the window (you should see its current setting (Auto)towards the right side of the window on the Value drop-down).
    Click on the drop-down and select a setting other than Auto (Try 100 Mb Full) and then click OK to close the window.

    The "other end" of the cable you use in your office may be faulty (or the cable run itself.
    Test it with a cable tester.

    Right click My Computer then Properties and Hardware and Device manager.
    Open the Network Adapters and right click on yours. Right click and select properties. Click the Advanced tab and scroll down and highlight Speed/Duplex settings.
    (FD means Full Duplex and HD means Half Duplex in there). Try different settings until you find one that works.

    You also tested the plugs were the cable connects and tried a new cable?

    Do you not have IT staff at work to ask about this?
    Sounds like some type of port security is in place, given that the desktop works but no other devices work with that particular port in the office.
