    Ok so I have had this problem for months, I really have tried everything I can think of but just don't get what is happening.

    Set Up:

    • Speedtouch ADSL modem - DHCP server - 192.168.1.254
    • Linksys wireless router - connected to modem - 192.168.1.253
    • A PC is conncted to the wireless router via ethernet, and I use a laptop via wireless.
    The Problem:

    Mostly the laptop works fine over wireless. But whenever I do something over the local network (view files on the pc, try to back up laptop files to the pc, or even access laptop files from the pc) the laptop's wireless connection drops out within 30 sec. By 'drop out', the laptop still says it is connected but has no internet access. I cannot access the wireless router by IP address when this happens either.

    The worst bit is that when I disconnect and try reconnecting to the wireless router, I can't - the only solution is to restart the
    ADSL modem (rebooting the linksys router doesn't help..). Also, I do get disconnected and can't reconnect very occasionally when I'm just using internet (once a day max).

    What I've Tried:

    • ipconfig/all - didn't see anything unusual
    • changing DHCP to the wireless router. Now this was weird - I couldn't get DNS working when I did this. Tried using openDNS but no luck, and when I decided to copy the modem's DNS settings, they were all set as 0.0.0.0. (???)
    • tried hours of googling for the problem, turning off all antivirus programs etc, lots...
    Other Info

    Don't think it is the laptop - works fine on other networks, lan etc.
    When the laptop is close to the wireless router (i.e 5 bars instead of the normal 3), the problem doesn't seem to occur.

    I really can't figure this out... any help or suggestions would be MUCH appreciated. I have spent hours trying to fix this but can't figure out what's wrong. Thanks :)

    my initaill reaction was to see if there are firmware updates avaible for the modem/router/ and a driver update for the pc network adapter
    BUT when you said
    wasnt so sure - BUT it would be worth looking at the firmware and see what updates are available
    If we could have makes and exact models of all devices - we should be able to post the information here

    This only ever happens on wireless - the ethernet connected PC still works fine on the internet when the "drop out" occurs
    correct ?

    Lets try a few things -
    When its working normally - make a note of all the status light on the router and modem
    then when it "drops out" check those light and post any difference here

    again when its working correclty lets see an ipconfig /all and various ping tests and post results here- see below
    Now when it drops out repeat all the tests and save to something like notepad and when you have internet access post back here - make sure we know which is which

    Also lets see what the wireless landscape looks like - post and image of the xirrus wireless tool - see details below


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

    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}
    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
    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.

    Are you cascading the routers (Speedtouch LAN connected to Linksys WAN port)? If so, have you changed the Linksys's LAN from the default 192.168.1.x? If the routers are connected that way and both using the same LAN subnet often you will get no internet access and other times you may get internet access sometimes. The simplest, not necessarily best, solution is to change the Linksys LAN to use something else, such as 192.168.3.x.
