    Hello friends. I recently changed my ISP to Telstra cable due to internet issues. However, similar issues seem to have arisen. I am getting disconnection issues regardless of whether I'm using ethernet or wireless. They seem to happen relatively frequently and I constantly lag or disconnect from games as a result. I try to fix the issue in the "networking and sharing centre" and it says my computer has no default gateway. How can I fix this issue?

    [EDIT] - My netbook and other people in the house don't seem to have any issues.

    can we see an xirrus screen shot and three ping shots and another ipconfig 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.

    ------------------------------------------------------------------------
    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 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.

    If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply

    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.​

    For windows version, XP, Vista, W7
    Hold the Windows key and press R

    Now 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
    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
    right click in the command prompt 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

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

    ------------------------------------------------------------------------
    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.

    If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply

    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)


    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

    To post a screen shot of the active window.
    Windows XP
    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.

    Vista or Windows 7
    you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool
    http://www.bleepingcomputer.com/tutorials/how-to-use-the-windows-snipping-tool/

    Windows 8
    you can use the snipping tool > Open Snipping Tool (From the Windows 8 Start Screen, type "snip" and press enter.
    >Press the Esc. key.
    >go back to your Windows 8 start screen - Swipe from left or press Window Button
    >Press Ctrl+PrntScr button to use Snipping Tool

    Hello, I cannot really pinpoint exactly when the internet disconnects, but I know that when I'm on ethernet it never seems to be working.

    can we start with that then , so ignore the xirrus bit
    and disconnect from the wireless

    with a cable connected from PC to router
    check the cable - see if there is a light on the router associated with the cable port used , also check if you have a green/yellow light on the PC LAN port (some PCs do not have any lights on the LAN port - so ignore)

    and post an ipconfig /all
