    I have Linksys Wireless-G Broadband Router Model WRT54G2 V1, Motorola Surfboard Modem Model SB5100 currently connected ISP Comcast to my desktop. Router not connected yet. I need help to install this router for use with Acer Extensa 5420 Laptop. Comcast referred me to Cisco for support but my router is out of warrarty. All equipment is hand-me-down and I cannot affort to pay for support. Last use of this site was great info. Please help as I tried to go to Cisco website but was not sure what I needed to click on for this help. I am beginner. Thanks so much.

    with the PC connected to the Modem lets see an ipconfig /all - details below
    user manual for modem here http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000073893.pdf
    info on modem here http://broadband.motorola.com/catalog/product_documents/SB5100 datasheet.pdf

    plug the router into the power and then do a reset the router back to factory condition - reset button on the back - hold in for about 30secs

    If the modem is just a modem and NOT a router
    then connect the modem to the internet input on the route
    and connect a PC to one of the 4 LAN connections

    Now powercycle all the equipment


    How to power cycle

    “power cycle” process to reboot or reset the modem/router
    • Switch off all the devices modem, router and computers also unplug their power cables.
    • Wait at least 30 seconds.
    • Plug the power cords back in, but don’t switch them on.
    • First turn on the modem and then wait for it to settle - all lights to become stable.
    • Next switch on the router (if a seperate device ) and the allow the lights to become stabile.
    • Now turn on your computer, You should now be able to access the Internet.

    once you have that all setup if it still does not work - post back an ipconfig /all

    {ipconfig /all}
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

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

    Hold the Windows key and press R, then type CMD then 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 to notepad and then automatically open notepad.

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

    The modem is a modem only, so follow the above instructions plus make sure nothing is connected to the modem's USB port.
