    Hi,

    I use a USB Dongle for internet... and I use my Laptop to sharing my Internet Connection with another laptop in the same room (Using Wireless AdHoc)... Hmm I know how to do this.. I have it WORKING FINE.. The Problem I am having is that the Internet Sharing keeps stopping

    I mean for e.g. I start Internet Connection Sharing it works.
    then
    20 Minutes later
    Wireless status shows No Internet Connection
    and the only way to start it back up again is by
    1. Going into sharing disable it [APPLY]
    2. Go Back into sharing then sharing it with Ethernet Network Connection [APPLY]
    3. Go Back into sharing then disable it [APPLY]
    4. Go Back into sharing then select Wireless Network Connection [APPLY]
    Then it starts working again for the next 20 minutes..

    is there a way to fix this as you can see its a annoying process to get it to start up again.


    Thanks in Advance.

    is it only the sharing - if you switch off sharing and use just the one laptop - does it still disconnect ?
    OR
    is it the shared laptop that loses connection - you could try the USB wireless adapter on that laptop and see if that disconnects at all ?

    No the sharing disconnects on the laptop that's sharing. all connected laptops devices disconnect. and yes even if i use just one it still disconnects after a while.

    its not a sharing issue then, just a general connection issue in which case do this with just the PC connected and not sharing


    would you post the following tests when its working OK and then repeat ALL the tests when it disconnects and make sure you also tells which tests posted are for what condition

    if you are also connected by wireless include the xirrus screen shots

    Please post back here the make and exact model of the router and if separate, the make and exact model of the modem

    Also please make a note of the status of the light on the modem and on the router when working normally - post back here and then when disconnected post the status of the lights here again if changed

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

    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 paste here.


    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://wpc.475a.edgecastcdn.net/00475A/XirrusWiFiInspectorSetup.1.2.0.exe

    {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 NET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/Products/Wi-Fi-Inspector/xirruswifiinspectorguide1-2-0.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, 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/

    Ok maybe i used the wrong word "Disconnects"... let me correct that.. sharing screws up... Wireless Connection between all devices is still on.. File Sharing is on. Except the internet.. and from the top process I mentioned .. I didn't say I have to disconnect the wireless and back on.. I don't even have to touch the wireless adapter all I have to do is
    Switch off Sharing
    Switch on with LAN
    Switch off Sharing
    Switch on Sharing with WirelessLAN

    and all devices start getting internet again.





    THESE ARE THE RESULTS FORM THE LAPTOP THAT IS SHARING... I KNOW YOU WANT THE OTHER ONE... but need to wait for few minutes LOL I had just redid it so its working right now.

    so if you are just connected to the modem on 1 PC and have NO wireless on and NO sharing ON at all - then you DO NOT disconnect from the internet at all - and the PC works fine all the time
    is that correct

    The Main Laptop Never has Internet Down Time.. Only the Devices that are sharing this computers Internet Have No Internet. If I do the same setup on XP on my other laptop use that as the Main Laptop then.. Sharing never stops.

    very useful information

    I would check for an updated wireless driver on the PC manufacturers website
    if that is not the later
    i would got to device manager and uninstall the wireless adapter - then restart the PC and let windows redetect the wireless adapter hardware and re-install the driver and tcp/ip bindings

    Sadly Did all of that already Also updated the drivers.. I don't understand what the problem could be... After a while it just says Wireless Status No Internet Connection... I look in the Modem Sharing.. and Sharing is ticked everything seems ok.. unless I stop sharing and enable with another adapter and stop and renable with wireless it won't work.

    I mean If I just stop sharing the reenable it with Wireless Lan it won't start I have to switch sharing to another adapter before I can go back to Wireless Lan.. that tells me its not my Wireless Lan that is at problem its something to do with sharing... but i dunno what it could possibly be..
