  1. i am unable to reset my router back to default username/password setting.ive been able to reset it in the past, but i cant remember what i did.

    i have held the reset button down for 90 secs. then i unplugged the router while still holding down the reset button for an additional 90 secs. and finally plugged the power back in again still holding the reset button for an additional 90 secs.

    ive tried switching between different web browser. default gateway is

    tried using cmd prompt. used ipconfig /release. ipconfig /renew. just for the heck of it.

    ive also read that this same model and version is giving alot of people trouble as far as resetting it goes.

    honestly, im not sure what firmware i have installed. im not sure how to check it... if that may be the issue.

    while trying to login to router via firefox, i get the security level 15 message

    cant remember my username/password

    Sounds like your router needs a hard reset, the following has helped me in some cases, but be aware, if these procedures don't work, than your router has gone bye bye, it's junk.

    To reset your router to factory defaults, use the following procedure:

    1) Power down all computers, the router, and the modem, and unplug them from the wall.
    2) Disconnect all wires from the router.
    3) Power up the router and allow it to fully boot (1-2 minutes).
    4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
    5) Power down the router.
    6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
    7) Power up the router and allow it to fully boot (1-2 minutes).
    8) Power up the computer (if the computer has a wireless card, make sure it is off).
    9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
    10) Open your browser and point it to This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.

    If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.

    If you cannot get "Reply from ..." in step 9 above, your router is dead.

    If there's some time left on any type or warrenty for this device, I would recommend using it, that is if in fact your router is dead.

    Good luck.............hope this helps! :)
