    Hi guys,

    I can't seem to connect to the internet via the Ethernet port on my laptop, but the built-in Wi-Fi card works perfectly fine. I normally use Wi-Fi, as our signal is very strong, even if I go outside and up the road, I can still connect.

    My issue is that although I don't need it, I'd like to setup Ethernet for the first time since installing Windows 7. I've had Windows 7 since April 2011, and prior to that I used Windows Vista. From memory, I don't think Vista had any problems with connecting via Ethernet back before I moved house, but this was over two years ago.

    My laptop is an ASUS X58L, and the NIC identified by Device Manager, is a Realtek RTL8139/810x Family Fast Ethernet NIC. Going into the properties, I can see that I have the latest Windows 7 driver installed - 6.111.723.2009, however prior to this I had the driver that came with the machine (when it was running Vista), which was 6.108.331.2008 and tried updating from Device Manager, but for some reason it said that I had the best driver already installed. To install the 2009 Windows 7 driver, I had to manually download it from Realtek. With either of the drivers, connecting via Ethernet doesn't work, and I'm confused as to what to do next.

    Help is much appreciated,
    Dylan. :)

    The device is not disabled in Device Manager. Upon right-clicking, it gives me the option to disable it.

    Sorry, I forgot to mention that I have the latest BIOS update for my laptop, and Windows Network Diagnostics reports that the Ethernet cable may be broken, but I know it works for other devices in our house. The icon in the bottom-right corner changes to the Ethernet (wired connection) icon, but it has a red cross and I can't seem to get past this stage.

    Can you download and run the wireless test tool in my signature below then right click and choose run as admin and post the results. Do it with the network cable plugged in as well as wireless

    Its showing the card not connected that normally is a faulty or faulty card have you tried another cable? Does the port on the router light up when the cable is plugged in? Lets tidy up a bit first remove all the tunnel
    Open Start Menu
    Type In: Device Manager
    Select Device Manager
    Click the View menu from the top
    Select Show Hidden Devices (Must be check before continuing)
    Scroll down and expand Network Adapters
    Right-Click a duplicated Microsoft 6to4 Adapter or Microsoft ISATAP Adapter
    Select Uninstall
    Click OK for the pop-up warning message
    Repeat and repeat for each of the unwanted duplicated adapter
    Close Device Manager when finish
    download the internet reset in my signature right click and choose run as admin
    Disable ipv6 for the card and wireless

    Hello. I found two duplicates of 'Microsoft ISATAP Adapter' and uninstalled them, and also unchecked IPv6 via Network Connections. Following that, I restarted my laptop, and opened up Device Manager again to see that they had been reinstalled. Fortunately however, IPv6 has not been re-enabled.

    I did try accessing the internet before restarting but to no avail. After restarting it with Wi-Fi turned off and an Ethernet cable plugged in, the same thing happened - a wired connection icon with a red cross. Going into Network Connections, still shows that a cable is not plugged in.

    Odd really, as the same cable works in my dad's laptop.

    I seem to be having the same problem. It was working fine and then when I hooked the ethernet cable to my xbox (Still works fine) and plugged it back into the computer, nothing. I tried your steps deleted 2 copies of the ISATAP Adapter as well and nothing happened. I plugged in my ethernet cable into my roommate's computer and it worked fine.

    Does the cable click when put in the pc is there a light on the network card and does the router port light up. It sound like a faulty network card. You might try in the bios disabling the network card boot windows then go back to the bios and enable it and try again

    I've managed to 'fix' my issue.

    Not sure exactly how it's supposed to work but the driver update for Windows 7 for my Realtek RTL8139/810x network card doesn't work. I therefore came across an 'update' in Windows Updates, listing the Vista driver update for some odd reason. I decided to install that and for some miraculous reason, I can connect again using the same Ethernet cable as before.

    Screenshots from Device Manager below.

    Rather strange how its own driver refused to work, but the Vista driver worked. :confused:

    Hi,

    Sometimes, drivers designed for other OS's work for newer ones. Kinda strange how it works isn't it? o_O
