    Hi I'm having problems with my internet connection. It used to work no problem but just in this last week it has started playing up. I have tried resetting the router and setting up the internet connection again from scratch but it hasn't solved the problem.

    It will connect to the wireless network but then drop it every so often, sometimes it will go to local access only, next minute it will lose connection all together. This is very frustrating and I have no idea how to fix it :(

    Can anyone give me some advice?

    Also, having issues with Microsoft Office - it won't save anything without crashing.... this is a relatively new problem as well.

    It's windows vista that I am using.

    i have moved your thread to a post of its own

    lets see the following information when the connection is working and then repeat all the tests when it fails



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

    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

    Start> Run {search bar in Vista}> 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/library/wifitools.php
    Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
    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

    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.

    Do I have to do these things while trying to connect to my wireless at home? I am currently hardwired to a network at work.

    need to do them where ever you have the problem connecting and dropping , I'm assuming this is at home on a wireless network or does it also disconnect from the work wireless network ?

    so that's all showing as working - now we need to see all the same results when it fails

    is this the work or home network ?? as the channel should be changed to avoid interference
