    I store and share family photos on my computer. When my daughter wanted to see them this morning, I logged on my account from her laptop, found the folder where the photos located and opened the folder. Then, I walked out of her room. Five minutes later, she complained that she couldn't get on the Internet. I did a "ipconfig /all" and found that the media state of the gigabit adapter, bluetooth adapter and the wireless adapter were all "media disconnected." I could ping 127.0.0.1 all right but nothing else. I couldn't ping the router.

    I plugged the laptop directly to the router using an ethernet cable. There was no connection. The indicator on the router was not lit.

    Device manager said the wireless adapter (Intel Centrino Advanced-N 6200 AGN) "is working properly."

    The computer is a Lenovo T410 running Windows 7 Enterprise.

    Where should I go from here? Thanks for help.

    Hi:Welcome to TSG:

    Sounds like a router issue

    Are any other pc's affected ?

    See if this gets you up and running:

    Tips on setting up broadband connection, courtesy of Johnwill

    You don't need any setup disk to configure a broadband router.


    Reset the router to factory defaults by holding the reset button down for 15 seconds with power on. The following procedure should get you a connection with any broadband modem that is configured to use DHCP for the router connection, such as cable modems, and many DSL modems. If you require PPPoE configuration for the DSL modem, that will have to be configured to match the ISP requirements.
    • Turn off everything, the modem, router, computer.
    • Connect the modem to the router's WAN/Internet port.
    • Connect the computer to one of the router's LAN/Network ports.
    • Turn on the modem, wait for a steady connect light.
    • Turn on the router, wait for two minutes.
    • Boot the computer.

    When the computer is completely booted, let's see this.

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous command output!

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 206.190.60.37

    PING yahoo.com

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    Thank you for your prompt reply.

    You are correct. It was the router. The computer I used to post the question was connected to the router through an Ethernet cable. Since it was working, I did not suspect that the router was having a problem. It turned out the wired portion of the router was working but the wireless portion was not (never thought of this possibility before). I unplugged the router, waited a couple of minutes, plugged it back in and everything worked.
