    So basically i have a new fujitsu laptop that is around a week old. The first couple days were fine, but on the third day the internet went down on the laptop. I went to check my router( I am on the second floor, router on the first), and everything was fine and when i came back up the internet was back.
    Lately, it's been happening again and again, and usually gets resolved very quickly, but still really frustrating. None of the other computers in the house are having a problem. So today it goes down for a longer time and i search around online and try to solve it, I turn my router off and back on and sure enough the internet came back. It's ok for 30-40 minutes before it goes down again.
    On the connection page, it will go from "connections are available" to "connecting to network" to "Identifying... no internet access" and it just repeats. I'm on a
    Does anybody know how to solve this?

    itmay be a dns issue
    or wireless interference

    quite a few tests to do and post back results

    would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
    Make sure you also indicate on the reply which tests are for what condition.

    please include the xirrus screen shots for both conditions - see how below.

    Please post back here the make and exact model of the router and if you have a separate modem, the make and exact model of the modem.

    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG , Webroot etc

    ------------------------------------------------------------------------
    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 the results in a reply here.
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

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

    This should also work for windows 8
    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 into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy

    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.

    Ping Tests

    Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
    (A new dialogue box - black with white font, will appear on screen ):

    For Windows 8
    to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

    Type the following command
    Ping {then a space and then add the number that is shown against the item labelled "default gateway" shown in the results from the ipconfig /all}
    Post back the results in a reply here

    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
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
    You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {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 will need to have NET Framework installed for the WiFi Inspector to function.
    On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

    Run the program

    A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.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.

    post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)

    To post a screen shot of the active window.
    1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    OR
    2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

    To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
    Full details are available 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. "A desirable signal level for a robust Wi-Fi connection will be green".
    note: the signal level is a negative number, so for example -88 is worst and -40 is better

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

    if you want to optimise base station position and signal strength / dead spots use
    http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

    the wireless signal is -73 and -65 ,so did you move the machine at all - as below -70 will not give a robust connection ,and the wireless maybe oscillating , hence the reason you drop off the internet

    i would log into the router and change to use channel 1 and remove the wide 40mhz setting - see if that helps at all

    also move closer to the router and get a good signal -50ish and see if it drops at all then

    also goto the Fujitsu support website and update the wireless driver
