    Hello,
    I have a Packard Bell easynote ts and my internet connection drops after a varied length of time, trouble is I have to reboot my computer to get back online
    I have Windows 7 and down at the bottom right corner On my notifications area it has 5 white bars when I am connected to internet, but when my internet starts to drop it first shows 5 grey bars with a yellow symbol and says wireless connections are available but I can't find Virgin Media, then it changes to 5 bars saying no wireless connections are available. I have an Ethernet cable but when I plug this in it remains with the crossed out symbol.
    I have had Virgin Media engineers out to look and its definitely not their problem and it only drops on my laptop.
    Any suggestions
    Brian

    this is the only PC that disconnects correct and you have others on wireless that continue to work

    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.

    Please make a note of the status of the lights on the modem and on the router when working normally - post that light status here.
    Now when the internet disconnects make a note of the status of the lights for the modem and router here again. also note which have changed.

    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
    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.

    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
    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
    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 209.183.226.152
    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

    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

    Thanks for replying
    Ok I have the results of my internet whilst its connected I shall wait until it drops before I repeat the test and put them in the same email.
    I have an atheros AR5B97 wireless network adapter, and a Microsoft Virtual WiFi Miniport adapter installed, My internet security is Microsoft Security Essentials and firewall is just Microsoft Firewall with advanced Security. I am using Malware bytes also.
    My router is a Virgin Media Superhub router and has a model number VMDG480, there are 3 sidelights, one is 'traffic' which blinks blue rapidly, the second is 'ready' which is a steady green and the third is 'wireless' which blinks green rapidly.
    Anyway rather typically my internet connection is working perfectly, so I cant provide you with the second test results.
    Hope this answers your questions so far.

    Just offering this here to try if you want to, when it fails next time.

    Save it on your desktop as RenewConnection.bat
    and click on it, when you have lost your connection. It may help, or it may not, but it will not damage or change anything.

    Code:
    @echo off
    ipconfig /release
    ipconfig /release6
    ipconfig /renew
    ipconfig /renew6
    pause

    You can type the commands (and on testing the two lines with 6 in it are not needed) but you can also save it as a batch file on your desk top and click it.

    Save the code below to notepad and save it as "Renew Connection.bat"

    Code:
    @echo off
    ipconfig /release
    ipconfig /renew
    pause
    When your connection fails click on the bat file and see if it helps.

    It will open a cmd prompt and finish with 'press any key to continue'.
