    So for the longest time now my internet just goes in and out constantly. I'm always on wireless so I'm thinking I might need a new wireless router, but I'm not sure.

    When I moved out of my parents house and got my own internet hooked up it all started. Internet would go in and out a lot both on wireless and when I was hooked up to local connection. I had Charter and told them and they gave me a new modem but problem stayed so I just assumed it was the wireless router I had bought. I moved to another city and am still using the same wireless router and got another modem from Charter in my new house. Problem is still there and is way worse.

    About every 5 mins I lose connection for about 30 secs. It always says connected though but pages won't load and says connection issues but like I said my wireless connection always shows excellent connection. About once a week it will go out and not come back unless I unplug the modem and router and plug it all back in.

    Any help?

    can we see the following when its connected OK and then repeat all the tests when it disconnects and post all the results - make sure we know which results apply to which condition



    ------------------------------------------------------------------------
    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
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste
    ------------------------------------------------------------------------

    Start> Run {search bar in Vista/W7}> CMD to open a DOS window and type:

    Type the following command
    Ping {plus the number thats shown against the default gateway shown in above ipconfig /all}
    Post back the results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping google.com
    Post back the results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping 209.183.226.152
    post back results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://wpc.475a.edgecastcdn.net/00475A/XirrusWiFiInspectorSetup.1.2.0.exe

    {If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You need NET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/Products/Wi-Fi-Inspector/xirruswifiinspectorguide1-2-0.aspx

    post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

    If you are using the Mac OS then use http://www.istumbler.net/

    you have ICS internet connection sharing - enabled - did you want that on are you sharing the internet via your PC

    if not then see below

    I would also log into the wireless router and switch the wireless channel to use channel 1 as you have a few channels on 11 and a new one appeared which may have caused the disconnection - although a weak signal

    this how you turn ICS ON - so use the same instructions to turn off

    ------------------------------------------------------------------------
    TURN ON ICS
    TURN ON ICS - for internet sharing
