    A few weeks back my computer would intermitently connect to the internet. I have gone through 3 modems from Comcast. It's not the modem it's my comp. Modem works on anything but my computer. I have reinstalled drivers, gone into BIOS, cleaned everything, rebooted many times, reset router, shutdown down Bonjour, tried 4 other ethernet cords, I really don't know what else to do. The computer keeps saying "Ethernet cable unplugged or broken." Can anybody help?

    Realtek PCIe GBE Ethernet Adapter

    Thanks

    Probably a defective ethernet adapter. Try a USB ethernet adapter.

    This may be a dumb question. Have you tried to change the cable between PC and the router?

    Since you've gone through 3 cable modems, it's not going to be a bad ethernet port in it.
    It's my guess the ethernet cable or the computer's ethernet device is bad.

    I had the ethernet device in a Dell OptiPlex 755 minitower go bad a couple of years ago.
    I resolved the problem by installing an ethernet card.

    ---------------------------------------------------------------

    You appear to have a Dell Inspiron 3847 minitower.
    Is that correct?

    It appears to have a Realtek RTL8111G/RTL8151GD-CG/8111F gigabit ethernet device.
