    Realtek PCIe Gigabit NIC connect/disconnect problem


    Friend has a HP 110-230t CTO Desktop PC that has a Realtek PCIe GBE Family Controller and a Qualcomm Atheros AR9000 Series 802.11n WiFi.

    The WiFi works correctly but the Realtek NIC continually connects then disconnects.

    I've uninstalled it then rebooted and let Win 10 reload the driver, no help.
    I downloaded and installed the original Windows 8 driver that came with this PC, no help.
    I then updated the driver from Device Manager, again no help.

    I suspect a hardware failure in the Realtek chip but was wondering if anyone here had any other suggestions.

    Since this el-cheapo PC (no power supply, uses laptop style external power adapter) has no expansion slots, I can't add a PCIe NIC so I've ordered a Plugable USB 2.0 to 10/100/1000 Gigabit Ethernet LAN Wired Network Adapter (PC has only USB 2.0 ports, no USB 3.0) which should resolve the problem.

    Any other ideas I should pursue? I'll have the USB adapter on the 27th.

    HP has hardware tests for networking.
    Download and install the UEFI diagnostics for Windows: (right upper corner of the webpage)
    HP PC Hardware Diagnostics | HP® Official Site

    Run the full hardware tests and then the component test > networking.
    See if it confirms the suspected hardware problem.

    Thanks Z, already did that. Doesn't even see the NIC.

    I'll have the new USB NIC tomorrow then will see if that resolves the problem. It should.
