    Hello,

    I switched on my laptop today and it wouldn't connect to the internet because of an 'unidentified network' problem. Last night before I went to bed it was surfing the net fine and then this morning, nothing. No one has touched the laptop overnight and it was switched off all night so I have no idea how this has happened. I'm using my internet connection via my iPhone with no problems.

    I've already tried several things to try and fix the problem - I've reinstalled all network adapters, have fiddled with IPv4 settings, have deleted and re-setup my network connection, and have restored Windows to a previous point. I can't connect my laptop to the router using a cable because I live in a bock of flats where lots of people share the same router and it's locked in a security box, so I'm just using a wireless connection.

    Apologies if this error has been posted about before but I wanted to start a new thread so I could explain the actions I'd already taken to try and fix things. Judging from a Google search this seems to be a pretty common Vista problem.

    Any help you could give me would be much appreciated, I've been trying to fix this for 6 hours now :( Thank you.

    can we see the following - i guess it maybe difficult to do if you do not have another PC -
    maybe for the ipconfig /all you can post some details from the phone - i will post template to help



    ------------------------------------------------------------------------
    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
    ------------------------------------------------------------------------

    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 paste here.


    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.
