    What does Device Manager show you for Network Adapters? Any yellow marks? If yes then you need to download and install the driver for the network card.

    Hi orety,

    In addition, can you please do a Power Cycle?

    Also, please post an ipconfig /all output for review.

    Did you also do Power Cycle?

    Lets uninstall/reintall the problematic network adapter from Device Manager, when you restart your computer it should automatically reinstall the driver back. Please see this tutorial.

    In addition, you may try resetting both TCPI/IP and Winsock.
    Click on Start=> All Programs => Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
    Restart the computer after and test your connection again.

    If the resets didn't work, we can try assigning Static IPs in your computer, are you familiar with this process? You will need to run an ipconfig /all from a working computer so that we can use the same subnet.
