    Hi,

    I can connect to the Internet when my laptop's connected directly to the modem but not through my wireless router. My laptop can connect to the router, but then I have no Internet access. (I've tried resetting my router and modem.)

    When I do ipconfig /all (without connecting to the modem), I get:

    I can't ping my router (192.168.1.1); the request times out and/or says that the destination net is unreachable. I can ping Google and my DNS.

    Thanks to Google, I tried:

    netsh winsock reset
    netsh int ip reset resetlog.txt

    But those didn't work. Is my router just busted?

    If you could please help, it would be much appreciated.

    make and models of these devices

    if you connect by cable to the router will it work ?

    any other devices working on the router

    make and model of the PC
    what windows version, vista, W7 or W8 ?

    connect directly to the modem with a cable - as you say this works - and post an ipconfig /all

    also do a powercycle whenever you make a change
    ------------------------------------------------------------------------

    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 1 to 5 minutes,
    • Plug the power cords back in, but don’t switch them on.
    • First turn on the modem and then wait for a few minutes for it to settle and all the lights to become stable.
    • Next switch on the router (if a separate device) and then wait for a few minutes for it to settle and all the lights to become stable.
    • Now turn on your computer, You should now be able to access the Internet.
