    Hi! After moving to a new home, I'm having trouble getting a wired connection working. Same modem and router as the previous home, same PC. Different ISP, but both are Shaw cable re-packagers.

    router
    CISCO Linksys E900, Factory Reset, with latest firmware 1.0.06
    modem
    THOMPSON DCM 475

    motherboard
    SAPPHIRE Pure Black P67 Hydra
    USB adapter
    USB wifi, Dlink DWA-160
    Operating system
    Windows 7 64
    Ethernet Adapter
    Marvell Yukon 88E8057 Family PCI-E Gigabit Ethernet Controller
    latest driver version 11.45.4.3


    I have only a PC and an android connected, occasionally and android tablet as well.

    The PC can connect via wifi, if ethernet is disabled and then modem, router, PC restarted, but I can't seem to figure out a way to get the ethernet connection to work. I've tried DHCP and Static IP configurations, and I've tried connecting the ethernet directly to the modem instead of the router, but to no avail. I believe I've managed at times to access the router from the PC (only with static IP), but never the internet as well. I've tried 3 cat 5 cables as well.

    Here are some pictures with more details of my config

    I've been banging my head against this for 8+ hours...can anyone see what I'm missing?

    what ip does the router use
    connect to wireless which is working
    set up the ethernet to obtain an IP automatically and post back a new ipconfig /all here
    ------------------------------------------------------------------------
    ipconfig /all


    We would like to see the results from an ipconfig /all - post back the results in a reply here.

    If you cannot access the internet with this PC
    You will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.
    If you do not have another PC
    Do you have a phone connected to the internet - can you photograph the result and post the image in a reply
    Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the information above those entries​

    For Windows 8 or Windows 10
    To open a Cmd Prompt or an Administrator Cmd prompt from the Desktop.
    Use Windows + X Keys together and choose Command Prompt (Admin) from the list.
    Or Right click on the windows icon - bottom left hand side - A menu appears - choose Command Prompt (Admin)

    For windows version, XP, Vista, W7
    Hold the Windows key and press R
    Now type CMD
    Now press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):​

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.

    I supplied an ipconfig /all in the above link. Please take a look at the image entitled "DCHP ipconfig"
    (in other words, while the connection was set to get IP and dns automatically, not static)

    I'll try the netsh commands later when I can afford to be without internet for a while again :)

    In the mean time, I wonder how you don't see all 8 or so images from that link...strange... Anyways here's the one specific image with the IP Config.
