    Hi there, I am having connection issues with my laptop involving my wireless adapter (I assume), since I am able to connect to the internet via a different laptop, Xbox and phones in the household. It is a Dell M5010 and the problem has only recently occurred. Any help in resolving this, or rectifying the problem would be much appreciated.
    Thanks in advance.

    check if the wireless is switched on - use the FN + F key - find the key with a wireless symbol on - and try that make sure the wireless is switched on

    otherwise can we see an ipconfig /all
    ------------------------------------------------------------------------
    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

    what firewall security suite have you now or ever had on the PC - like norton,mcafee, avg - a trial version
    would you provide the following
    ------------------------------------------------------------------------
    Ping Tests
    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
    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.

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

    Type the following command
    Ping 192.168.0.1
    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
    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 ("Go Advanced" button) and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Or if you are using Vista/Windows 7 you can use the "snipping tool" which is found in
    Start> All programs> Accessories> Snipping Tool

    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/ or
    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
