    My internet connection is strong, all 5 bars. Randomly though, the connection will be dropped down to Limited Connectivity. Once I disconnect, then reconnect, the internet connection is fine. I can continue browsing with full signal strength. A few minutes later, it's been dropped to limited connectivity again.

    We have three laptops in the house. The two Dell's we have are both dropping the internet. The HP laptop hasn't dropped once. My laptop has never had this problem on any other networks I use (I'm only home for the month from school). My parents have said that they never had this problem before on the other Dell either. The fact that the HP still hasn't dropped the connection once makes me thing it might not be the router? I have no idea. Any suggestions???

    Are all Machines connected by wireless

    A bit contradictory really -
    Lets assume a PC issue as other devices are solid assuming they are connected in the same way - ie cable or wireless

    I would suggest first looking at the DELL service TAG numbers on a label on the PC and using that info to goto the dell website and updating the network adapter drivers

    If wireless lets see an xirrus screen shot - it maybe interference - but would expect all to drop connection

    Lets also see the ipconfig /all and ping tests when its working and also when it disconnects - see below

    ------------------------------------------------------------------------
    {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
    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.

    {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 here

    -> (XP - enter the following in the RUN box)
    cmd /k ipconfig /all
    -> (Vista or Windows 7 - enter the following in the Search box)

    A black box will appear on the screen -
    rightclick in the box
    select all
    enter
    control key + C key - to copy

    then reply here and
    control key + V to paste
    ------------------------------------------------------------------------
    {Ping Tests}

    Type the following command
