    Hi there guys. I've have had some great help from all you guys here and I need your help again.
    So my internet recently has been acting weird, not for just one laptop, but for all of them, The only thing that seems to not disconnect is the computer hooked up to the routers. I thought it was time for a new router so I bought two new ones to replace the old ones, so I did. They were replaced but the problem still continued! I updated the router firmware and it would fix it temporarily, but after a day it started again.
    Please let me know if you need any info at all.

    make and models of the router
    How are they connected - why two

    confused by that statement - would you provide detail
    is it just hardwired devices , or wireless or ????

    when its all working - can we have a status of all the lights on the routers and then when disconnects whats the status of the lights again

    also on one PC - can we the following ipconfig /all , xirrus and ping tests and then again when it disconnects

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

    If you are using the Mac OS then use http://www.istumbler.net/

    The router is a Tedna W268R

    I meant to say one router, sorry.

    What I mean by that is the laptop's internet disconnects, but the desktop internet works fine and never has these disconnects.

    Here is my ipconfig/all.

    change your wireless channel on the router to use 11 - see if that helps

    is the laptop wireless and desktop cable

    lets see the laptops ipconfig /all and pings when it disconnects
